It makes a single pass over the tree, collecting the sql - fragments for the various nodes in the tree . - The major operations are - - - Select statement minimization. Multiple nodes in the query tree - that can be part of a single SQL select statement are merged. e.g. a - Filter node that is the input of a Project node can typically share the - same SQL statement. - - - Alpha-renaming. As a result of the statement minimization above, there - could be name collisions when using correlated subqueries - - Filter( - b = Project( c.x - c = Extent(foo) - ) - exists ( - Filter( - c = Extent(foo) - b.x = c.x - ) - ) - ) - The first Filter, Project and Extent will share the same SQL select statement. - The alias for the Project i.e. b, will be replaced with c. - If the alias c for the Filter within the exists clause is not renamed, - we will get c.x = c.x, which is incorrect. - Instead, the alias c within the second filter should be renamed to c1, to give - c.x = c1.x i.e. b is renamed to c, and c is renamed to c1. - - - - Join flattening. In the query tree, a list of join nodes is typically - represented as a tree of Join nodes, each with 2 children. e.g. - - a = Join(InnerJoin - b = Join(CrossJoin - c = Extent(foo) - d = Extent(foo) - ) - e = Extent(foo) - on b.c.x = e.x - ) - If translated directly, this will be translated to - FROM ( SELECT c.*, d.* - FROM foo as c - CROSS JOIN foo as d) as b - INNER JOIN foo as e on b.x' = e.x - It would be better to translate this as - FROM foo as c - CROSS JOIN foo as d - INNER JOIN foo as e on c.x = e.x - This allows the optimizer to choose an appropriate join ordering for evaluation. - - - - Select * and column renaming. In the example above, we noticed that - in some cases we add - SELECT * FROM ... - to complete the SQL - statement. i.e. there is no explicit PROJECT list. - In this case, we enumerate all the columns available in the FROM clause - This is particularly problematic in the case of Join trees, since the columns - from the extents joined might have the same name - this is illegal. To solve - this problem, we will have to rename columns if they are part of a SELECT * - for a JOIN node - we do not need renaming in any other situation. - - . - - - Renaming issues. When rows or columns are renamed, we produce names that are unique globally with respect to the query. The names are derived from the original names, with an integer as a suffix. e.g. CustomerId will be renamed to CustomerId1, CustomerId2 etc. Since the names generated are globally unique, they will not conflict when the columns of a JOIN SELECT statement are joined with another JOIN. - - Record flattening. SQL server does not have the concept of records. However, a join statement produces records. We have to flatten the record accesses into a simple alias.column form. - - - - Building the SQL. There are 2 phases - - - Traverse the tree, producing a sql builder - - - - Write the SqlBuilder into a string, renaming the aliases and columns - as needed. - - - In the first phase, we traverse the tree. We cannot generate the SQL string right away, since - - The WHERE clause has to be visited before the from clause. - - extent aliases and column aliases need to be renamed. To minimize - renaming collisions, all the names used must be known, before any renaming - choice is made. - - - To defer the renaming choices, we use symbols - - . These are renamed in the second phase. Since visitor methods cannot transfer information to child nodes through parameters, we use some global stacks, - - - A stack for the current SQL select statement. This is needed by - - to create a - list of free variables used by a select statement. This is needed for - alias renaming. - - - A stack for the join context. When visiting an extent, - we need to know whether we are inside a join or not. If we are inside - a join, we do not create a new SELECT statement. - - - - - Global state. To enable renaming, we maintain - - The set of all extent aliases used. - The set of all parameter names. - The set of all column names that may need to be renamed. - - Finally, we have a symbol table to lookup variable references. All references to the same extent have the same symbol. - - - Sql select statement sharing. Each of the relational operator nodes - - Project - Filter - GroupBy - Sort/OrderBy - - can add its non-input (e.g. project, predicate, sort order etc.) to the SQL statement for the input, or create a new SQL statement. If it chooses to reuse the input's SQL statement, we play the following symbol table trick to accomplish renaming. The symbol table entry for the alias of the current node points to the symbol for the input in the input's SQL statement. - - Project(b.x - b = Filter( - c = Extent(foo) - c.x = 5) - ) - The Extent node creates a new SqlSelectStatement. This is added to the - symbol table by the Filter as {c, Symbol(c)}. Thus, c.x is resolved to - Symbol(c).x. - Looking at the project node, we add {b, Symbol(c)} to the symbol table if the - SQL statement is reused, and {b, Symbol(b)}, if there is no reuse. - Thus, b.x is resolved to Symbol(c).x if there is reuse, and to - Symbol(b).x if there is no reuse. - - - - - - - Every relational node has to pass its SELECT statement to its children - This allows them (DbVariableReferenceExpression eventually) to update the list of - outer extents (free variables) used by this select statement. - - - - - Nested joins and extents need to know whether they should create - a new Select statement, or reuse the parent's. This flag - indicates whether the parent is a join or not. - - - - - VariableReferenceExpressions are allowed only as children of DbPropertyExpression - or MethodExpression. The cheapest way to ensure this is to set the following - property in DbVariableReferenceExpression and reset it in the allowed parent expressions. - - - - - Maintain the list of (string) DbParameterReferenceExpressions that should be compensated, viz. - forced to non-unicode format. A parameter is added to the list if it is being compared to a - non-unicode store column and none of its other usages in the query tree, disqualify it - (For example - if the parameter is also being projected or compared to a unicode column) - The goal of the compensation is to have the store index picked up by the server. - String constants are also compensated and the decision is local, unlike parameters. - - - - - Set and reset in DbComparisonExpression and DbLikeExpression visit methods.

If these fail then a new implementation of this service can be registered - on to provide an appropriate resolution. - - - - - Returns the for the given connection. - - The connection. - The provider factory for the connection. - - - - A DbContext instance represents a combination of the Unit Of Work and Repository patterns such that - it can be used to query from a database and group together changes that will then be written - back to the store as a unit. - DbContext is conceptually similar to ObjectContext. - - - DbContext is usually used with a derived type that contains properties for - the root entities of the model. These sets are automatically initialized when the - instance of the derived class is created. This behavior can be modified by applying the - attribute to either the entire derived context - class, or to individual properties on the class. - The Entity Data Model backing the context can be specified in several ways. When using the Code First - approach, the properties on the derived context are used to build a model - by convention. The protected OnModelCreating method can be overridden to tweak this model. More - control over the model used for the Model First approach can be obtained by creating a - explicitly from a and passing this model to one of the DbContext constructors. - When using the Database First or Model First approach the Entity Data Model can be created using the - Entity Designer (or manually through creation of an EDMX file) and then this model can be specified using - entity connection string or an object. - The connection to the database (including the name of the database) can be specified in several ways. - If the parameterless DbContext constructor is called from a derived context, then the name of the derived context - is used to find a connection string in the app.config or web.config file. If no connection string is found, then - the name is passed to the DefaultConnectionFactory registered on the class. The connection - factory then uses the context name as the database name in a default connection string. (This default connection - string points to .\SQLEXPRESS on the local machine unless a different DefaultConnectionFactory is registered.) - Instead of using the derived context name, the connection/database name can also be specified explicitly by - passing the name to one of the DbContext constructors that takes a string. The name can also be passed in - the form "name=myname", in which case the name must be found in the config file or an exception will be thrown. - Note that the connection found in the app.config or web.config file can be a normal database connection - string (not a special Entity Framework connection string) in which case the DbContext will use Code First. - However, if the connection found in the config file is a special Entity Framework connection string, then the - DbContext will use Database/Model First and the model specified in the connection string will be used. - An existing or explicitly created DbConnection can also be used instead of the database/connection name. - A can be applied to a class derived from DbContext to set the - version of conventions used by the context when it creates a model. If no attribute is applied then the - latest version of conventions will be used. - - - - - Interface implemented by objects that can provide an instance. - The class implements this interface to provide access to the underlying - ObjectContext. - - - - - Gets the object context. - - The object context. - - - - Constructs a new context instance using conventions to create the name of the database to - which a connection will be made.

The default - implementation of this method does nothing, but it can be overridden in a derived class - such that the model can be further configured before it is locked down. - - - Typically, this method is called only once when the first instance of a derived context - is created. The model for that context is then cached and is for all further instances of - the context in the app domain. This caching can be disabled by setting the ModelCaching - property on the given ModelBuidler, but note that this can seriously degrade performance. - More control over caching is provided through use of the DbModelBuilder and DbContextFactory - classes directly. - - The builder that defines the model for the context being created. - - - - Internal method used to make the call to the real OnModelCreating method. - - The model builder. - - - - Returns a DbSet instance for access to entities of the given type in the context, - the ObjectStateManager, and the underlying store. - - - See the DbSet class for more details. - - The type entity for which a set should be returned. - A set for the given entity type. - - - - Returns a non-generic DbSet instance for access to entities of the given type in the context, - the ObjectStateManager, and the underlying store. - - The type of entity for which a set should be returned. - A set for the given entity type. - - See the DbSet class for more details. - - - - - Saves all changes made in this context to the underlying database. - - The number of objects written to the underlying database. - Thrown if the context has been disposed. - - - - Validates tracked entities and returns a Collection of containing validation results. - - Collection of validation results for invalid entities.

If there is a failure, throws an exception message - in some scenarios (note that we respond to failure rather than anticipate failure, - avoiding repeated checks in the inner materialization loop) - - - - - Notify ObjectContext that we are about to start materializing an element - - - - - Notify ObjectContext that we are finished materializing the element - - - - - Events raised when the shaper has finished enumerating results. Useful for callback - to set parameter values. - - - - - Used to handle the read-ahead requirements of value-layer queries. This - field indicates the status of the current value of the _rootEnumerator; when - a bridge data reader "accepts responsibility" for the current value, it sets - this to false. - - - - - The enumerator that the value-layer bridge will use to read data; all nested - data readers need to use the same enumerator, so we put it on the Shaper, since - that is something that all the nested data readers (and data records) have access - to -- it prevents us from having to pass two objects around. - - - - - Optimized enumerator for queries not including nested results. - - - - - Enumerates (for each row in the input) an array of all coordinators producing new elements.

In particular, - root level elements (T) are returned only after aggregating all child elements. - - - - - Requires: the row is currently positioned at the start of an element. - Reads all rows in the element and sets up state for the next element (if any). - - - - - Reads rows until the start of a new element is found. If no element - is found before all rows are consumed, returns false. - - - - - Describes the state of this enumerator with respect to the _rowEnumerator - it wraps. - - - - - No rows have been read yet - - - - - Positioned at the start of a new root element. The previous element must - be stored in _previousElement. We read ahead in this manner so that - the previous element is fully populated (all of its children loaded) - before returning. - - - - - Positioned past the end of the rows. The last element in the enumeration - has not yet been returned to the user however, and is stored in _previousElement. - - - - - Positioned past the end of the rows. The last element has been returned to - the user. - - - - - Wraps RowNestedResultEnumerator and yields results appropriate to an EntityReader instance. In particular, - yields RecordState whenever a new element becomes available at any depth in the result hierarchy. - - - - - Gets depth of coordinator we're currently consuming. If _depth == -1, it means we haven't started - to consume the next row yet. - - - - - Translates query ColumnMap into ShaperFactory.

The EntityKey construction is the tricky part. - - - - - Visit(ScalarColumnMap) - Pretty basic stuff here; we just call the method that matches the - type of the column. Of course we have to handle nullable/non-nullable - types, and non-value types. - - - - - Visit(VarRefColumnMap) - This should throw; VarRefColumnMaps should be removed by the PlanCompiler. - - - - - Allocates a slot in 'Shaper.State' which can be used as storage for - materialization tasks (e.g. remembering key values for a nested collection) - - - - - Return the CLR type we're supposed to materialize for the TypeUsage - - - - - Return the CLR type we're supposed to materialize for the EdmType - - - - - Get the ConstructorInfo for the type specified, and ensure we keep track - of any security requirements that the type has. - - - - - Retrieves object mapping metadata for the given type.

(!A+!B) . (!C+!D) - To compute the CNF form in parallel, we negate the expression (by swapping One and Zero sinks) - and collect negation of the literals along the path.

To find out the - generated view we go to the ObjectItemCollection and see if it is not-null. If the ObjectItemCollection - is non-null, we get the view generation assemblies that it might have cached during the - Object metadata discovery.If there are no view generation assemblies we switch to the - runtime view generation strategy. If there are view generation assemblies, we get the list and - go through them and see if there are any assemblies that are there from which we have not already loaded - the views. We collect the views from assemblies that we have not already collected from earlier. - If the ObjectItemCollection is null and we are in the view generation mode, that means that - the query or update is issued from the Value layer and this is the first time view has been asked for. - The compile time view gen for value layer queries will work for very simple scenarios. - If the users wants to get the performance benefit, they should call MetadataWorkspace.LoadFromAssembly. - At this point we go through the referenced assemblies of the entry assembly( this wont work for Asp.net - or if the viewgen assembly was not referenced by the executing application). - and try to see if there were any view gen assemblies. If there are, we collect the views for all extents. - Once we have all the generated views gathered, we try to get the view for the extent passed in. - If we find one we will return it. If we can't find one an exception will be thrown. - If there were no view gen assemblies either in the ObjectItemCollection or in the list of referenced - assemblies of calling assembly, we change the mode to runtime view generation and will continue to - be in that mode for the rest of the lifetime of the mapping item collection. - - - - - The class loads an MSL file into memory and exposes CSMappingMetadata interfaces. - The primary consumers of the interfaces are view genration and tools. - - - For Example if conceptually you could represent the CS MSL file as following - --Mapping - --EntityContainerMapping ( CNorthwind-->SNorthwind ) - --EntitySetMapping - --EntityTypeMapping - --TableMappingFragment - --EntityKey - --ScalarPropertyMap ( CMemberMetadata-->SMemberMetadata ) - --ScalarPropertyMap ( CMemberMetadata-->SMemberMetadata ) - --DiscriminatorProperyMap ( constant value-->SMemberMetadata ) - --EntityTypeMapping - --TableMappingFragment - --EntityKey - --ScalarPropertyMap ( CMemberMetadata-->SMemberMetadata ) - --ComplexPropertyMap - --ComplexTypeMap - --ScalarPropertyMap ( CMemberMetadata-->SMemberMetadata ) - --ScalarProperyMap ( CMemberMetadata-->SMemberMetadata ) - --DiscriminatorProperyMap ( constant value-->SMemberMetadata ) - --AssociationSetMapping - --AssociationTypeMapping - --TableMappingFragment - --EndPropertyMap - --ScalarPropertyMap ( CMemberMetadata-->SMemberMetadata ) - --ScalarProperyMap ( CMemberMetadata-->SMemberMetadata ) - --EndPropertyMap - --ScalarPropertyMap ( CMemberMetadata-->SMemberMetadata ) - --EntityContainerMapping ( CMyDatabase-->SMyDatabase ) - --CompositionSetMapping - --CompositionTypeMapping - --TableMappingFragment - --ParentEntityKey - --ScalarPropertyMap ( CMemberMetadata-->SMemberMetadata ) - --ScalarPropertyMap ( CMemberMetadata-->SMemberMetadata ) - --EntityKey - --ScalarPropertyMap ( CMemberMetadata-->SMemberMetadata ) - --ScalarPropertyMap ( CMemberMetadata-->Constant value ) - --ComplexPropertyMap - --ComplexTypeMap - --ScalarPropertyMap ( CMemberMetadata-->SMemberMetadata ) - --DiscriminatorProperyMap ( constant value-->SMemberMetadata ) - --ScalarPropertyMap ( CMemberMetadata-->Constant value ) - The CCMappingSchemaLoader loads an Xml file that has a conceptual structure - equivalent to the above example into in-memory data structure in a - top-dwon approach. - - - The loader uses XPathNavigator to parse the XML. The advantage of using XPathNavigator - over DOM is that it exposes the line number of the current xml content. - This is really helpful when throwing exceptions.

Flatten unions contained as left children of LOJs: LOJ(A, Union(B, C)) -> LOJ(A, B, C). - 2. Rewrite flat LOJs into nested LOJs. The nesting is determined by FKs between right cell table PKs. - Example: if we have an LOJ(A, B, C, D) and we know there are FKs from C.PK and D.PK to B.PK, - we want to rewrite into this - LOJ(A, LOJ(B, C, D)). - 3. As a special case we also look into LOJ driving node (left most child in LOJ) and if it is an IJ, - then we consider attaching LOJ children to nodes inside IJ based on the same principle as above. - Example: LOJ(IJ(A, B, C), D, E, F) -> LOJ(IJ(LOJ(A, D), B, LOJ(C, E)), F) iff D has FK to A and E has FK to C. - This normalization enables FK-based join elimination in plan compiler, so for a query such as - "select e.ID from ABCDSet" we want plan compiler to produce "select a.ID from A" instead of - "select a.ID from A LOJ B LOJ C LOJ D". - - - - - A class that handles creation of cells from the meta data information. - - - - - Boolean members have a closed domain and are enumerated when domains are established i.e. (T, F) instead of (notNull). - Query Rewriting is exercised over every domain of the condition member. If the member contains not_null condition - for example, it cannot generate a view for partitions (member=T), (Member=F).

The builder simulates order preservation by 'lifting' order keys in - the expression tree. For instance, source.Sort(o).Where(f) is rewritten as - source.Where(f).Sort(o) since otherwise the sort keys would be ignored. - In general, the lifter works as follows: - - The input to the operator is matched against a series of patterns for intrinsically - ordered expressions. - - For each pattern, the lifter encodes the compensation required for each of the - lifting operators that can be applied. - - - - - Returns a lifter instance which supports lifting the intrinsic order of the given - source expression across specific operations (filter, project, oftype, skip, and limit) - - - Lifting only occurs for expressions that are ordered. Each of the nested - OrderByLifterBase class implementations represents one or two of the ordered patterns with - the exception of the PassthroughOrderByLifter. The latter class represents expressions - without intrinsic order that therefore require no lifting. - - - - - Represents an expression of the form: source.Skip(k, o).Limit(k2) - - - - - Represents an expression of the form: source.Sort(o).Limit(k) - - - - - Represents an expression of the form: source.Skip(k, o).Limit(k2).Project(p) - - - This class is also used to represent expressions of the form: source.Skip(k, o).Project(p).Limit(k). - As a result, the rewrites must be spelled out entirely (the implementation cannot assume that - _limit exists in a particular position in the tree) - - - - - Represents an expression of the form: source.Sort(o).Limit(k).Project(p) - - - This class is also used to represent expressions of the form: source.Sort(o).Project(p).Limit(k). - As a result, the rewrites must be spelled out entirely (the implementation cannot assume that - _limit exists in a particular position in the tree) - - - - - Represents an expression of the form: source.Skip(k, o).Project(p) - - - - - Represents an expression of the form: source.Skip(k, o) - - - - - Represents an expression of the form: source.Sort(o).Project(p) - - - - - Represents an expression for which there is an explicit order by: source.Sort(o) - - - - - Used for sources that do not have any intrinsic order. - - - - - Tries to get a translator for the given property info. - If the given property info corresponds to a Visual Basic property, - it also initializes the Visual Basic translators if they have not been initialized - - - - - This method is used to determine whether client side evaluation should be done, - if the property can be evaluated in the store, it is not being evaluated on the client - - - - - Facet encapsulating information necessary to initialize a LINQ projection - result. - - - - - Requires: other has the same type as this and refers to the same CLR type - Determine whether this Metadata is compatible with the other based on record layout. - - - - - Produces an expression initializing an instance of ClrType (given emitters for input - columns) - - - - - Yields expected types for input columns.

These sub-expressions may map to query parameters (e.g. local variables), - to constants (e.g. literals 'new DateTime(2008, 1, 1)') or query sub-expression - (e.g. 'context.Products'). Parameter expressions are replaced with QueryParameterExpression - nodes. All other elements are swapped in place with either expanded expressions (for sub-queries) - or constants. Where the expression includes mutable state that may influence the translation - to a query, a Func(Of Boolean) delegate is returned indicating when a recompilation is necessary. - - - - - Performs funcletization on the given expression. Also returns a delegates that can be used - to determine if the entire tree needs to be recompiled. - - - - - Replaces context parameter (e.g. 'ctx' in CompiledQuery.Compile(ctx => ctx.Products)) with constant - containing the object context. - - - - - Returns a function indicating whether the given expression and all of its children satisfy the - 'localCriterion'. - - - - - Determines whether the node may be evaluated locally and whether - it is a constant. Assumes that all children are also client expressions. - - - - - Determines whether the node may be evaluated locally and whether - it is a variable. Assumes that all children are also variable client expressions. - - - - - Determines whether the node may be evaluated as a compiled query parameter. - Assumes that all children are also eligible compiled query parameters. - - - - - Determine whether the given CLR type is legal for an ObjectParameter or constant - DbExpression. - - - - - Creates the next available parameter name. - - - - - Walks the expression tree and replaces client-evaluable expressions with constants - or QueryParameterExpressions. - - - - - Returns a delegate indicating (when called) whether a change has been identified - requiring a complete recompile of the query. - - - - - Compiles a delegate returning the value of the given expression. - - - - - Inlines a funcletizable expression. Queries and lambda expressions are expanded - inline. All other values become simple constants. - - - - - Gets the appropriate LINQ expression for an inline ObjectQuery instance. - - - - - Replaces expression patterns produced by the compiler with approximations - used in query translation. For instance, the following VB code: - x = y - becomes the expression - Equal(MethodCallExpression(Microsoft.VisualBasic.CompilerServices.Operators.CompareString(x, y, False), 0) - which is normalized to - Equal(x, y) - Comment convention: - CODE(Lang): _VB or C# coding pattern being simplified_ - ORIGINAL: _original LINQ expression_ - NORMALIZED: _normalized LINQ expression_ - - - - - If we encounter a MethodCallExpression, we never need to lift to lift to null. This capability - exists to translate certain patterns in the language. In this case, the user (or compiler) - has explicitly asked for a method invocation (at which point, lifting can no longer occur). - - - - - Gets a dictionary mapping from LINQ expressions to matched by those expressions. Used - to identify composite expression patterns. - - - - - Handle binary patterns: - - VB 'Is' operator - - Compare patterns - - - - - CODE: x - ORIGINAL: Convert(x, typeof(object)) - ORIGINAL(Funcletized): Constant(x, typeof(object)) - NORMALIZED: x - - - - - Returns true if the given expression is a constant '0'. - - - - - Handles MethodCall patterns: - - Operator overloads - - VB operators - - - - - Identifies and normalizes any predicate argument in the given call expression.

Otherwise, returns a new call expression - with a normalized predicate argument. - - - - - Determines whether the given call expression has a 'predicate' argument (e.g. Where(source, predicate)) - and returns the ordinal for the predicate. - - - Obviously this method will need to be replaced if we ever encounter a method with multiple predicates. - - - - - Determines whether the given expression of the form Lambda(Coalesce(left, Constant(false)), ...), a pattern - introduced by the VB compiler for predicate arguments. Returns the 'normalized' version of the expression - Lambda((bool)left, ...) - - - - - This method exists solely to support creation of valid relational operator LINQ expressions that are not natively supported - by the CLR (e.g. String > String). This method must not be invoked. - - - - - Create an operator relating 'left' and 'right' given a relational operator. - - - - - Try to create an operator relating 'left' and 'right' using the given operator. If the given operator - does not define a known relation, returns false. - - - - - CODE(C#): Class.Compare(left, right) - ORIGINAL: MethodCallExpression(Compare, left, right) - NORMALIZED: Condition(Equal(left, right), 0, Condition(left > right, 1, -1)) - Why is this an improvement? We know how to evaluate Condition in the store, but we don't - know how to evaluate MethodCallExpression... Where the CompareTo appears within a larger expression, - e.g. left.CompareTo(right) > 0, we can further simplify to left > right (we register the "ComparePattern" - to make this possible). - - - - - Encapsulates an expression matching some pattern. - - - - - Gets pattern kind. - - - - - Gets pattern kind. - - - - - Matches expression of the form x.CompareTo(y) or Class.CompareTo(x, y) - - - - - Gets left-hand argument to Compare operation. - - - - - Gets right-hand argument to Compare operation. - - - - - LINQ query provider implementation. - - - - - Constructs a new provider with the given context.

Used - by the ObjectStateManager. - - - - - Add a DataContractAttribute to the proxy type, based on one that may have been applied to the base type. - - - From http://msdn.microsoft.com/en-us/library/system.runtime.serialization.datacontractattribute.aspx: A data contract has two basic requirements: a stable name and a list of members. The stable name consists of the namespace uniform resource identifier (URI) and the local name of the contract. By default, when you apply the DataContractAttribute to a class, it uses the class name as the local name and the class's namespace (prefixed with "http://schemas.datacontract.org/2004/07/") as the namespace URI. You can override the defaults by setting the Name and Namespace properties. You can also change the namespace by applying the ContractNamespaceAttribute to the namespace. Use this capability when you have an existing type that processes data exactly as you require but has a different namespace and class name from the data contract. By overriding the default values, you can reuse your existing type and have the serialized data conform to the data contract. - The first attempt at WCF serialization of proxies involved adding a DataContractAttribute to the proxy type in such a way so that the name and namespace of the proxy's data contract matched that of the base class. This worked when serializing proxy objects for the root type of the DataContractSerializer, but not for proxy objects of types derived from the root type. Attempting to add the proxy type to the list of known types failed as well, since the data contract of the proxy type did not match the base type as intended. This was due to the fact that inheritance is captured in the data contract. So while the proxy and base data contracts had the same members, the proxy data contract differed in that is declared itself as an extension of the base data contract. So the data contracts were technically not equivalent. The approach used instead is to allow proxy types to have their own DataContract. Users then have at least two options available to them. The first approach is to add the proxy types to the list of known types. The second approach is to implement an IDataContractSurrogate that can map a proxy instance to a surrogate that does have a data contract equivalent to the base type (you could use the base type itself for this purpose). While more complex to implement, it allows services to hide the use of proxies from clients. This can be quite useful in order to maximize potential interoperability. - - - - - Factory for creating proxy classes that can intercept calls to a class' members. - - - - - A hook such that test code can change the AssemblyBuilderAccess of the - proxy assembly through reflection into the EntityProxyFactory. - - - - - Dictionary of proxy class type information, keyed by the pair of the CLR type and EntityType CSpaceName of the type being proxied. - A null value for a particular EntityType name key records the fact that - no proxy Type could be created for the specified type. - - - - - Dictionary of proxy class type information, keyed by the proxy type - - - - - The runtime assembly of the proxy types. - This is not the same as the AssemblyBuilder used to create proxy types. - - - - - Return proxy type information for the specified O-Space EntityType. - - EntityType in O-Space that represents the CLR type to be proxied.

ColumnMaps are produced as part of the PlanCompiler - module of the bridge, and are consumed by the Execution phase of the bridge. - * Simple (scalar) columns (and UDTs) are represented by a SimpleColumnMap - * Record type columns are represented by a RecordColumnMap - * A nominal type instance (that supports inheritance) is usually represented - by a PolymorphicColumnMap - this polymorphicColumnMap contains information - about the type discriminator (assumed to be a simple column), and a mapping - from type-discriminator value to the column map for the specific type - * The specific type for nominal types is represented by ComplexTypeColumnMap - for complextype columns, and EntityColumnMap for entity type columns. - EntityColumnMaps additionally have an EntityIdentity that describes - the entity identity. The entity identity is logically just a set of keys - (and the column maps), plus a column map that helps to identify the - the appropriate entity set for the entity instance - * Refs are represented by a RefColumnMap. The RefColumnMap simply contains an - EntityIdentity - * Collections are represented by either a SimpleCollectionColumnMap or a - DiscriminatedCollectionColumnMap. Both of these contain a column map for the - element type, and an optional list of simple columns (the keys) that help - demarcate the elements of a specific collection instance. - The DiscriminatedCollectionColumnMap is used in scenarios when the containing - row has multiple collections, and the different collection properties must be - differentiated. This differentiation is achieved via a Discriminator column - (a simple column), and a Discriminator value. The value of the Discriminator - column is read and compared with the DiscriminatorValue stored in this map - to determine if we're dealing with the current collection. - NOTE: - * Key columns are assumed to be SimpleColumns. There may be more than one key - column (applies to EntityColumnMap and *CollectionColumnMap) - * TypeDiscriminator and Discriminator columns are also considered to be - SimpleColumns. There are singleton columns. - It is the responsibility of the PlanCompiler phase to produce the right column - maps. - The result of a query is always assumed to be a collection.

The specified Var is a valid ParameterVar in the IQT Command being converted: - This resolves simply to ParameterRefExpression. A Parameter that corresponds to the ParameterVar - is declared on the CQT DbCommandTree is this has not already been done. - 2. The specified Var is a ComputedVar that is defined locally to the Op being visited. In this case - The DbExpression produced by converting the VarDefOp that defines the Var is returned. - 3. Otherwise, the Var must have been brought into scope because the DbExpression that logically produces it is - being used in a DbExpressionBinding which is currently in scope. Each RelOpInfo on the ExpressionBindingScopes stack - is asked to resolve the Var, if one of the RelOpInfo scopes is tracking the Var it will construct an appropriate combination - of DbVariableReferenceExpression and PropertyRefExpressions that are sufficient to logically reference the Var. - If none of the 3 above conditions are satisfied then the Var is unresolvable in the CQT being constructed and - the original IQT Command must be considered invalid for the purposes of this conversion. - - The IQT Var to resolve - The CQT DbExpression to which the specified Var resolves - - - - Asserts that the specified Node has exactly 2 child Nodes - - The Node on which to Assert - - - - A SoftCastOp is intended to be used only for promotion (and/or equivalence) - and should be ignored in the CTree - - the softcast Op - the node - - - - Generates a name for the specified Var. - If the Var has a name (TryGetName), then we use the name to look up - the right alias generator, and get a column name from the alias generator - Otherwise, we simply get a name from the default alias generator - - the var in question - map to identify the appropriate alias generator - the default alias generator - list of already used names - - - - Called by both Visit(ProjectOp) and VisitSetOpArgument to create a DbProjectExpression - based on the RelOpInfo of the projection input and the set of projected Vars. - Note: - The projected Vars must have already been brought into scope (by one of the - methods such as EnterExpressionBinding, EnterVarDefScope, etc) before this method - is called, or the projected Vars will not be successfully resolved. - Both Visit(ProjectOp) and VisitSetOpArgument do this" - 1. Visit(ProjectOp) takes both DbExpressionBinding and VarDef based Vars into account - 2.

For non-record sourceTypes, this should consist of a single column that logically constitutes the entire 'table' - A VarInfoList containing VarInfo instances that correctly track the Var or Vars produced by the targetTable, in accordance with the shape of the sourceType - - - - Translate UnnestOp which is assumed (at this stage) to wrap a native ScalarOp - that returns a collection (e.g. a table-valued function node). - - - - - Builds up an "empty" projection over the input node. Well, in reality, we build - up a dummy projection node - which simply selects out some constant (which - is never used). This is useful in scenarios where the outputs are - uninteresting, but the input row count is - - the relOp node - - - - Build up a Project Op with exactly the Vars that we want. If the input is - a Project already, piggyback on it, and get the Vars we want. Otherwise, - create a new ProjectOp, and define the specified Vars - Note that the ProjectOp's output (element) type will be a record with the fields - in exactly the order specified by the projectionVars argument - - the input relOpNode to cap with a Project - List of vars we are interested in - A ProjectOp that produces the right set of Vars - - - - Massages the input to a join node. - If the input is a Filter(ScanTable), we throw in a dummy project over - this input. This projectOp simply looks at the "referenced" columns of - the table, and uses those as the projection Vars - Otherwise, sqlgen does not really know which columns are referenced, and - ends up adding a projection with all columns of the table. - NOTE: We may want to do this for Apply as well - - one of the inputs to the join node - RelopInfo for the transformed input - - - - Called by all Visitor pattern method that handle binary JoinOps (Inner, FullOuter, LeftOuter) - - The IQT Node that references the JoinOp - The CQT DbExpressionKind that represents the type of join to create - - - - Called by both CrossApply and OuterApply visitor pattern methods - command handling of both types of Apply operation - - The Node that references the ApplyOp - The CQT DbExpressionKind that corresponds to the ApplyOp (DbExpressionKind.CrossApply for CrossApplyOp, DbExpressionKind.OuterApply for OuterApplyOp) - A new CqtResult containing a DbApplyExpression with the correct ApplyType - - - - Called by VisitSetOp to convert each argument. - Determines whether a column-reordering projection should be applied to - the argument, and applies that projection if necessary during conversion - to a DbExpression. A different projection is applied if no Nodes higher in - the IQT consume the vars produced by the SetOp argument. - - A Node that provides one of the arguments to the SetOp - Defines the expected order of the Output Vars of the SetOp - The VarMap for the SetOp argument represented by the node. This specifies the Output (SetOp-produced) Var to Input (Argument-produced) Var mappings for the Vars in the outputVars enumerable. - A DbExpression that is the converted form of the argument (with an appropriate column-reording projection applied if necessary) - - - - Called by UnionAll, Intersect and Except (SetOp) visitor pattern methods - - The visited SetOp - The Node that references the SetOp - Alias to use when publishing the SetOp's Vars - Callback to construct the SetOp DbExpression from the left and right arguments - The DbExpression equivalent of the SetOp - - - - Convert SRO(e) => NewMultiset(Element(e')) - where e' is the CTree version of e - Add a Project over e, if it does not already have a ProjectOp - - - - - Convert SingleRowTableOp into NewMultisetOp(1) - a single element - collection. The element type of the collection doesn't really matter - - SingleRowTableOp - current subtree - CQT expression - - - - Translates the PhysicalProjectOp. Handles two cases. If the child is a ProjectOp, - then we simply piggyback on the ProjectOp method, but with our list of Vars. - Otherwise, we visit the child, and then create a DbProjectExpression above it. - The reason we special case the first scenario is because we do not want to add - an extra Project over a Project-over-Sort expression tree. This causes bad - problems later down the line - - the PhysicalProjectOp - current subtree - the CQT expression corresponding to this subtree - - - - The VarInfo class tracks how a single IQT Var should be referenced in terms of CQT Expressions. - The tracked Var must have been introduced by an IQT RelOp that was converted to a DbExpression that - is subsequently used in a DbExpressionBinding, otherwise the Var is either a ParameterVar or a locally - defined Var, which are tracked by the parameters collection of the Command and the VarDefScope - class, respectively. - An IQT Var that is tracked by a VarInfo instance is reachable in the following way: - 1. By a DbVariableReferenceExpression that references the Variable of the DbExpressionBinding that contains the DbExpression that logically publishes the IQT Var. - This is tracked by the PublisherName property of the RelOpInfo class, which is used to track Vars brought into scope by a DbExpressionBinding. - Without an enclosing RelOpInfo, the VarInfo is unbound and cannot be used to instantiate a CQT expression tree that is the equivalent of a VarRef of the IQT Var) - 2. By zero or more PropertyRefExpressions starting with a property of the DbVariableReferenceExpression created in step 1. - These PropertyRefExpressions are introduced on top of the DbVariableReferenceExpression because of Join or ApplyExpressions that - occur in the CQT between the expression that publishes the Var and the expression higher in the tree that contains a VarRefOp - to the IQT Var that must be resolved to a CQT DbExpression. In such cases the DbExpression that logically publishes - the IQT Var will have a record return Type. - The required property names are tracked, in order, in the PropertyPath property of this class. - The PrependProperty method is used to update the DbPropertyExpression path required to reach - the DbVariableReferenceExpression when the referenced Variable becomes part of such a record-typed output. - - - - - Constructs a new VarInfo instance that tracks the specified Var. - - The IQT Var that this VarInfo instance should track. - - - - Adds a property name to the beginning of the property path for this VarInfo instance. - Each time a new record structure is constructed on top of the expression that logically - publishes this var, another DbPropertyExpression is required around the DbVariableReferenceExpression used - to reach the Var in the CQT. Each new DbPropertyExpression must be added immediately around the - DbVariableReferenceExpression, with previous PropertyExpressions now referring to the new DbPropertyExpression. - Therefore the new property name added by this method is inserted at the start of the property path. - See the Visit methods for the Join/ApplyOps for examples of using this method to adjust the property path. - - The new property name to insert at the start of the property path for the Var tracked by this VarInfo instance - - - - Gets the Var tracked by this VarInfo instance - - - - - Gets the names, in order of use, that should be used to build DbPropertyExpression around an initial DbVariableReferenceExpression in order to build a DbExpression subtree that correctly references the tracked IQT Var - - - - - Groups a set of VarInfo instances together and allows certain operations (Bind/Unbind/PrependProperty) - to be performed on all instances in the VarInfoList with a single call. - - - - - Constructs a new, empty VarInfoList. - - - - - Constructs a new VarInfoList that contains the specified VarInfo instances. - - - - - Prepends the specified property name to the property path of all VarInfo instances in this list. - - - - - Attempts to retrieve the VarInfo instance that tracks the specified IQT Var, if it is contained by this VarInfoList. - - The required IQT Var - Contains the VarInfo instance that tracks the specified Var if this method returns true - True if this list contains a VarInfo instance that tracks the specified Var; otherwise false - - - - IqtVarScope is used to represent one or more IQT Vars that are currently in scope and can be mapped to a corresponding CQT DbExpression subtree. - - - - - Attempts to resolve the specified IQT Var by building or mapping to a CQT DbExpression subtree.

Even in this case, its not enough to take - the keys, and treat them as the keys of the union-all. What we’ll need to - do is to add a “branch” discriminator constant for each branch of the - union-all, and use this as the prefix for the keys. - For example, if I had: - Select c1, c2, c3... from ... - Union all - Select d1, d2, d3... from ... - And for the sake of argument, lets say that {c2} and {d2} are the keys of - each of the branches. What you’ll need to do is to translate this into - Select 0 as bd, c1, c2, c3... from ... - Union all - Select 1 as bd, d1, d2, d3... from ... - And then treat {bd, c2/d2} as the key of the union-all - Case 1: (actually, a subcase of Case 0): - Now, if the keys don’t align, then we can simply take the union of the - corresponding positions, and make them all the keys (we would still need - the branch discriminator) - Case 2: - Finally, if you need to “pull” up keys from either of the branches, it is - possible that the branches get out of whack. We will then need to push up - the keys (with nulls if the other branch doesn’t have the corresponding key) - into the union-all. (We still need the branch discriminator). - Now, unfortunately, whenever we've got polymorphic entity types, we'll end up - in case 2 way more often than we really want to, because when we're pulling up - keys, we don't want to reason about a caseop (which is how polymorphic types - wrap their key value). - To simplify all of this, we: - (1) Pulling up the keys for both branches of the UnionAll, and computing which - keys are in the outputs and which are missing from the outputs. - (2) Accumulate all the missing keys. - (3) Slap a projectOp around each branch, adding a branch discriminator - var and all the missing keys. When keys are missing from a different - branch, we'll construct null ops for them on the other branches. If - a branch already has a branch descriminator, we'll re-use it instead - of constructing a new one.

The keys of the NestOp are augmented with the keys of the - other join inputs: - JoinOp/ApplyOp(NestOp(X, ...), Y) => NestOp(JoinOp/ApplyOp(X, Y), ...) - In addition, if the NestOp is on a 'nullable' side of a join (i.e. right side of - LeftOuterJoin/OuterApply or either side of FullOuterJoin), the driving node - of that NestOp (X) is capped with a project with a null sentinel and - the dependant collection nodes (the rest of the NestOp children) - are filtered based on that sentinel: - LOJ/OA/FOJ (X, NestOp(Y, Z1, Z2, ..ZN)) => NestOp( LOJ/OA/FOJ (X, PROJECT (Y, v = 1)), FILTER(Z1, v!=null), FILTER(Z2, v!=null), ...

Additionally, its Outputs should be enhanced - to include any Vars produced by the ProjectOp - (3) The combination of both (1) and (2) -- both the vars define a collection, - and the input is also a nestOp. we handle this by first processing Case1, - then processing Case2. - - - - - Helper method for . - - - - - Fold nested MultiStreamNestOps into one: - MSN(MSN(X,Y),Z) ==> MSN(X,Y,Z) - NOTE: It would be incorrect to merge NestOps from the non-driving node - into one nest op, because that would change the intent. Instead, - we let those go through the tree and wait until we get to the top - level PhysicalProject, when we'll use the ConvertToSingleStreamNest - process to handle them. - NOTE: We should never have three levels of nestOps, because we should - have folded the lower two together when we constructed one of them. - We also remove unreferenced collections, that is, if any collection is - not referred to by the top level-NestOp, we can safely remove it from - the merged NestOp we produce. - - - - - ProjectOp(X,{a,CollectOp(PhysicalProjectOp(Y)),b,...}) ==> MsnOp(ProjectOp'(X,{a,b,...}),Y) - ProjectOp(X,{a,VarRef(ref-to-collect-var-Y),b,...}) ==> MsnOp(ProjectOp'(X,{a,b,...}),copy-of-Y) - Remove CollectOps from projection, constructing a NestOp - over the ProjectOp. - - - - - If we're going to eat the ProjectNode, then we at least need to make - sure we remap any vars it defines as varRefs, and ensure that any - references to them are switched. - - - - - We need to make sure that we remap the column maps that we're pulling - up to point to the defined var, not it's reference. - - - - - Convert a CollectOp subtree (when used as the defining expression for a - VarDefOp) into a reasonable input to a NestOp. - - - There are a couple of cases that we handle here: - (a) PhysicalProject(X) ==> X - (b) PhysicalProject(Sort(X)) ==> Sort(X) - - the child of the CollectOp - the collectionVar being defined - where to append the new collectionInfo - where to append the collectionNode - a bit vector of external references of the physicalProject - a bit vector of collection vars - - - - Case 2 for ProjectOp: NestOp is the input: - ProjectOp(NestOp(X,Y,...)) => NestOp'(ProjectOp'(X),Y,...) - Remove collection references from the ProjectOp and pull the - NestOp over it, adding any outputs that the projectOp added. - The outputs are important here; expanding the above: - P{a,n}(N{x1,x2,x3,y}(X,Y)) => N{a,x1,x2,x3,y}(P{a,x1,x2,x3}(X),Y) - Strategy: - (1) Determine oldNestOpCollectionOutputs - (2) oldNestOpNonCollectionOutputs = oldNestOpOutputs - oldNestOpCollectionOutputs; - (3) oldProjectOpNonCollectionOutputs = oldProjectOpOutputs - oldNestOpCollectionOutputs - (4) oldProjectOpCollectionOutputs = oldProjectOpOutputs - oldProjectOpNonCollectionOutputs - (5) build a new list of collectionInfo's for the new NestOp, including - only oldProjectOpCollectionOutputs. - (6) leftCorrelationVars = vars that are defined by the left most child of the input nestOpNode - and used in the subtrees rooted at the other children of the input nestOpNode - (7) newProjectOpOutputs = oldProjectOpNonCollectionOutputs + oldNestOpNonCollectionOutputs + leftCorrelationVars - (8) newProjectOpChildren = .... - Of course everything needs to be "derefed", that is, expressed in the projectOp Var Ids. - (9) Set ProjectOp's input to NestOp's input - (10) Set NestOp's input to ProjectOp. - - - - - SetOp common processing - - - The input to an IntersectOp or an ExceptOp cannot be a NestOp – that - would imply that we support distinctness over collections - which - we don’t. - UnionAllOp is somewhat trickier.

The tricky part is that - the UnnestOp produces a set of ColumnVars which may be referenced in other - parts of the query, and these need to be replaced by the corresponding Vars - produced by the defining expression. - There are essentially four cases: - Case 1: The UnnestOps Var is a UDT. Only the store can handle this, so we - pass it on without changing it. - Case 2: The UnnestOp has a Function as its input. This implies that the - store has TVFs, which it can Unnest, so we let it handle that and do - nothing. - Case 3: The UnnestOp Var defines a Nested collection. We'll just replace - the UnnestOp with the Input: - UnnestOp(VarDef(CollectOp(PhysicalProjectOp(input)))) => input - Case 4: The UnnestOp Var refers to a Nested collection from elsewhere. As we - discover NestOps, we maintain a var->PhysicalProject Node map. When - we get this case, we just make a copy of the PhysicalProject node, for - the referenced Var, and we replace the UnnestOp with it. - UnnestOp(VarDef(VarRef(v))) ==> copy-of-defining-node-for-v - Then, we need to update all references to the output Vars (ColumnVars) produced - by the Unnest to instead refer to the Vars produced by the copy of the subquery. - We produce a map from the Vars of the subquery to the corresponding vars of the - UnnestOp. We then use this map as we walk up the tree, and replace any references - to the Unnest Vars by the new Vars. - To simplify this process, as part of the ITreeGenerator, whenever we generate - an UnnestOp, we will generate a ProjectOp above it – which simply selects out - all Vars from the UnnestOp; and has no local definitions. This allows us to - restrict the Var->Var replacement to just ProjectOp. - - - - - Copies the given defining node for a collection var, but also makes sure to 'register' all newly - created collection vars (i.e. copied). - SQLBUDT #557427: The defining node that is being copied may itself contain definitions to other - collection vars.

We walk up the tree - in a bottom up fashion, and try to convert all structured types into flattened - record types - type constructors are first converted into flat record constructors - and then dismantled etc. The barrier points - Vars - are all converted into - scalar types, and all intermediate stages will be eliminated in transition. - The output from this phase includes a ColumnMap - which is used later by - the execution model to produce results in the right form from an otherwise - flat query - Notes: This phase could be combined later with the PropertyPushdown phase - - - - - Eliminates all structural types from the query - - current compiler state - - inferred s-space keys for TVFs that are mapped to entities - - - - The real driver.

In such cases, we - build up a new ComputedVar (with an expected value of null), and use that - in place of the inner var.

(Rationale: These must be in the same type hierarchy; or - the earlier stages of query would have failed. And, we end up - using the same "flat" type for every type in the hierarchy) - If this is a scalar type, then simply return the current node - If this is a collection type, then create a new softcastOp over the input - (the collection type may have changed) - Otherwise, we're dealing with a record type. Since our earlier - definitions of equivalence required that equivalent record types must - have the same number of fields, with "promotable" types, and in the same - order; *and* since we asked for all properties (see PropertyPushdownHelper), - the input must be a NewRecordOp, whose fields line up 1-1 with our fields. - Build up a new NewRecordOp based on the arguments to the input NewRecordOp, - and build up SoftCastOps for any field whose type does not match - - - - - Removes or rewrites cast to enum or spatial type. - - - operator. - - Current node. - - Visited, possible rewritten . - - - - - Converts Constant enum value to its underlying type.

For example: - Case when b1 then e1 else e2 end - gets translated into: - RecordOp(case when b1 then e1.a else e2.a end, - case when b1 then e1.b else e2.b end, - ...) - The property extraction is optimized by producing only those properties - that have actually been requested. - - Node corresponding to the CaseOp - Information about the type - Set of properties desired - - - - CollectOp - Nothing much to do - simply update the result type - - the NestOp - corresponding node - new subtree - - - - ComparisonOp - If the inputs to the comparisonOp are Refs/records/entitytypes, then - we need to flatten these out.

Additionally, for nominal types, this module produces typeid - values that can be used later to interpret the input data stream. - The goal of this module is to load up information about type and entityset metadata - used in the ITree. This module is part of the "StructuredTypeElimination" phase, - and provides information to help in this process. - This module itself is broken down into multiple parts. - (*) Loading type information: We walk the query tree to identify all references - to structured types and entity sets - (*) Processing entitysets: We walk the list of entitysets, and assign ids to each - entityset. We also create a map of id->entityset metadata in this phase. - (*) Processing types: We then walk the list of types, and process each type. This, - in turn, is also broken into multiple parts: - * Populating the Type Map: we walk the list of reference types and add each of - them to our typeMap, along with their base types. - * TypeId assignment: We assign typeids to each nominal (complextype/entitytype). - This typeid is based on a dewey encoding. The typeid of a type is typically - the typeid of its supertype suffixed by the subtype number of this type within - its supertype. This encoding is intended to support easy type matching - later on in the query - both for exact (IS OF ONLY) and inexact (IS OF) matches. - * Type flattening: We then "explode"/"flatten" each structured type - refs, - entity types, complex types and record types. The result is a flattened type - where every single property of the resulting type is a primitive/scalar type - (Note: UDTs are considered to be scalar types). Additional information may also - be encoded as a type property. For example, a typeid property is added (if - necessary) to complex/entity types to help discriminate polymorphic instances. - An EntitySetId property is added to ref and entity type attributes to help - determine the entity set that a given entity instance comes from. - As part of type flattening, we keep track of additional information that allows - us to map easily from the original property to the properties in the new type - The final result of this processing is an object that contains: - * a TypeInfo (extra type information) for each structured type in the query - * a map from typeid value to type. To be used later by result assembly - * a map between entitysetid value and entityset. To be used later by result assembly - NOTE: StructuredTypeInfo is probably not the best name for this class, since - it doesn't derive from TypeInfo but rather manages a collection of them. - I don't have a better name, but if you come up with one change this. - - - - - Process Driver - - - structured types referenced in the query - entitysets referenced in the query - entity types that have "free-floating" entity constructors - information on optimized discriminator patterns for entity sets - helper for rel properties - which types need a null sentinel - - - - - Fills the StructuredTypeInfo instance from the itree provided. - - - referenced structured types - referenced entitysets - free-floating entityConstructor types - discriminator information for entity sets mapped using TPH pattern - helper for rel properties - - - - Gets the "single" entityset that stores instances of this type - - - - - Get the entitysetid value for a given entityset - - the entityset - entitysetid value - - - - Gets entity sets referenced by the query. - - entity sets - - - - Find the TypeInfo entry for a type.

We first walk through the - list of properties for the current type, and "flatten" out the properties - that are themselves "structured". We then target each subtype (recursively) - and perform the same kind of processing. - Consider a very simple case: - Q = (z1 int, z2 date) - Q2: Q = (z3 string) -- Q2 is a subtype of Q - T = (a int, b Q, c date) - S: T = (d int) -- read as S is a subtype of T - The result of flattening T (and S) will be - (a int, b.z1 int, b.z2 date, b.z3 string, c date, d int) - - the root type to explode - - - - Helper for ExplodeType. - Walks through each member introduced by the current type, and - adds it onto the "flat" record type being constructed. - We then walk through all subtypes of this type, and process those as - well. - Special handling for Refs: we only add the keys; there is no - need to handle subtypes (since they won't be introducing anything - different) - - type in the type hierarchy - - - - Add the list of rel-properties for this type - - the type to process - - - - Create the flattened record type for the type. - Walk through the list of property refs, and creates a new field - (which we name as "F1", "F2" etc.) with the required property type. - We then produce a mapping from the original property (propertyRef really) - to the new property for use in later modules. - Finally, we identify the TypeId and EntitySetId property if they exist - - - - - Get the "new" type corresponding to the input type.

In the query tree, a list of join nodes is typically - represented as a tree of Join nodes, each with 2 children. e.g. - - a = Join(InnerJoin - b = Join(CrossJoin - c = Extent(foo) - d = Extent(foo) - ) - e = Extent(foo) - on b.c.x = e.x - ) - If translated directly, this will be translated to - FROM ( SELECT c.*, d.* - FROM foo as c - CROSS JOIN foo as d) as b - INNER JOIN foo as e on b.x' = e.x - It would be better to translate this as - FROM foo as c - CROSS JOIN foo as d - INNER JOIN foo as e on c.x = e.x - This allows the optimizer to choose an appropriate join ordering for evaluation. - - - - Select * and column renaming. In the example above, we noticed that - in some cases we add - SELECT * FROM ... - to complete the SQL - statement. i.e. there is no explicit PROJECT list. - In this case, we enumerate all the columns available in the FROM clause - This is particularly problematic in the case of Join trees, since the columns - from the extents joined might have the same name - this is illegal. To solve - this problem, we will have to rename columns if they are part of a SELECT * - for a JOIN node - we do not need renaming in any other situation. - - . - - - Renaming issues. When rows or columns are renamed, we produce names that are unique globally with respect to the query. The names are derived from the original names, with an integer as a suffix. e.g. CustomerId will be renamed to CustomerId1, CustomerId2 etc. Since the names generated are globally unique, they will not conflict when the columns of a JOIN SELECT statement are joined with another JOIN. - - Record flattening. SQL server does not have the concept of records. However, a join statement produces records. We have to flatten the record accesses into a simple alias.column form. - - - - Building the SQL. There are 2 phases - - - Traverse the tree, producing a sql builder - - - - Write the SqlBuilder into a string, renaming the aliases and columns - as needed. - - - In the first phase, we traverse the tree. We cannot generate the SQL string right away, since - - The WHERE clause has to be visited before the from clause. - - extent aliases and column aliases need to be renamed. To minimize - renaming collisions, all the names used must be known, before any renaming - choice is made. - - - To defer the renaming choices, we use symbols - - . These are renamed in the second phase. Since visitor methods cannot transfer information to child nodes through parameters, we use some global stacks, - - - A stack for the current SQL select statement. This is needed by - - to create a - list of free variables used by a select statement. This is needed for - alias renaming. - - - A stack for the join context. When visiting an extent, - we need to know whether we are inside a join or not. If we are inside - a join, we do not create a new SELECT statement. - - - - - Global state. To enable renaming, we maintain - - The set of all extent aliases used. - The set of all parameter names. - The set of all column names that may need to be renamed. - - Finally, we have a symbol table to lookup variable references. All references to the same extent have the same symbol. - - - Sql select statement sharing. Each of the relational operator nodes - - Project - Filter - GroupBy - Sort/OrderBy - - can add its non-input (e.g. project, predicate, sort order etc.) to the SQL statement for the input, or create a new SQL statement. If it chooses to reuse the input's SQL statement, we play the following symbol table trick to accomplish renaming. The symbol table entry for the alias of the current node points to the symbol for the input in the input's SQL statement. - - Project(b.x - b = Filter( - c = Extent(foo) - c.x = 5) - ) - The Extent node creates a new SqlSelectStatement. This is added to the - symbol table by the Filter as {c, Symbol(c)}. Thus, c.x is resolved to - Symbol(c).x. - Looking at the project node, we add {b, Symbol(c)} to the symbol table if the - SQL statement is reused, and {b, Symbol(b)}, if there is no reuse. - Thus, b.x is resolved to Symbol(c).x if there is reuse, and to - Symbol(b).x if there is no reuse. - - - - - - - Every relational node has to pass its SELECT statement to its children - This allows them (DbVariableReferenceExpression eventually) to update the list of - outer extents (free variables) used by this select statement. - - - - - Nested joins and extents need to know whether they should create - a new Select statement, or reuse the parent's. This flag - indicates whether the parent is a join or not. - - - - - VariableReferenceExpressions are allowed only as children of DbPropertyExpression - or MethodExpression. The cheapest way to ensure this is to set the following - property in DbVariableReferenceExpression and reset it in the allowed parent expressions. - - - - - Maintain the list of (string) DbParameterReferenceExpressions that should be compensated, viz. - forced to non-unicode format. A parameter is added to the list if it is being compared to a - non-unicode store column and none of its other usages in the query tree, disqualify it - (For example - if the parameter is also being projected or compared to a unicode column) - The goal of the compensation is to have the store index picked up by the server. - String constants are also compensated and the decision is local, unlike parameters. - - - - - Set and reset in DbComparisonExpression and DbLikeExpression visit methods. Maintains - global state information that the children of these nodes are candidates for compensation. - - - - - Set when it is is safe to ignore the unicode/non-unicode aspect. See for an example. - - - - - The current SQL Server version - - - - - Basic constructor. - - server version - - - - General purpose static function that can be called from System.Data assembly - - command tree - Server version - Parameters to add to the command tree corresponding to constants in the command tree.

If yes, sets global state variable - _forceNonUnicode. - - DBComparisonExpression or DbLikeExpression - - - - The grammar for the pattern that we are looking for is - - Pattern := Target OP Source | Source OP Target - OP := Like | In | Comparison - Source := Non-unicode DbPropertyExpression - Target := Target FUNC Target | DbConstantExpression | DBParameterExpression - FUNC := CONCAT | RTRIM | LTRIM | TRIM | SUBSTRING | TOLOWER | TOUPPER | REVERSE | REPLACE - - - - - Matches the non-terminal symbol "target" in above grammar. - - - - - Determines if the expression represents a non-unicode string column(char/varchar store type) - - - - - Determines if the expression represents a string constant or parameter with the facet, unicode=null. - - - - - Generate tsql for a constant.

Strings are wrapped in single quotes and escaped. Numbers are written literally. - - - - - The DISTINCT has to be added to the beginning of SqlSelectStatement.Select, - but it might be too late for that. So, we use a flag on SqlSelectStatement - instead, and add the "DISTINCT" in the second phase. - - - A - - - - - An element expression returns a scalar - so it is translated to - ( Select ... ) - - - - - - - - - - Only concrete expression types will be visited. - - - - - If we are in a Join context, returns a with the extent name, otherwise, a new - - with the From field set. - - - - - Gets escaped TSql identifier describing this entity set. - - - - - The bodies of , , - , are similar. - Each does the following. - - Visit the input expression - - Determine if the input's SQL statement can be reused, or a new - one must be created. - - Create a new symbol table scope - - Push the Sql statement onto a stack, so that children can - update the free variable list. - - Visit the non-input expression. - Cleanup - - - - A - - - - - Lambda functions are not supported. - The functions supported are: - - Canonical Functions - We recognize these by their dataspace, it is DataSpace.CSpace - Store Functions - We recognize these by the BuiltInAttribute and not being Canonical - User-defined Functions - All the rest - - We handle Canonical and Store functions the same way: If they are in the list of functions - that need special handling, we invoke the appropriate handler, otherwise we translate them to - FunctionName(arg1, arg2, ..., argn). - We translate user-defined functions to NamespaceName.FunctionName(arg1, arg2, ..., argn). - - - A - - - - - for general details. - We modify both the GroupBy and the Select fields of the SqlSelectStatement. - GroupBy gets just the keys without aliases, - and Select gets the keys and the aggregates with aliases. - Sql Server does not support arbitrarily complex expressions inside aggregates, - and requires keys to have reference to the input scope, - so in some cases we create a nested query in which we alias the arguments to the aggregates. - The exact limitations of Sql Server are: - - - If an expression being aggregated contains an outer reference, then that outer - reference must be the only column referenced in the expression (SQLBUDT #488741) - - - Sql Server cannot perform an aggregate function on an expression containing - an aggregate or a subquery. (SQLBUDT #504600) - - - Sql Server requries each GROUP BY expression (key) to contain at least one column - that is not an outer reference. (SQLBUDT #616523) - - - Aggregates on the right side of an APPLY cannot reference columns from the left side. - (SQLBUDT #617683) - - - The default translation, without inner query is: - SELECT - kexp1 AS key1, kexp2 AS key2,... kexpn AS keyn, - aggf1(aexpr1) AS agg1, .. aggfn(aexprn) AS aggn - FROM input AS a - GROUP BY kexp1, kexp2, .. kexpn - When we inject an innner query, the equivalent translation is: - SELECT - key1 AS key1, key2 AS key2, .. keyn AS keys, - aggf1(agg1) AS agg1, aggfn(aggn) AS aggn - FROM ( - SELECT - kexp1 AS key1, kexp2 AS key2,... kexpn AS keyn, - aexpr1 AS agg1, .. aexprn AS aggn - FROM input AS a - ) as a - GROUP BY key1, key2, keyn - - - A - - - - - - - - - - Not(IsEmpty) has to be handled specially, so we delegate to - . - - - A .

This gives us a (join)symbol. - Symbol(a).b gives us a join symbol, with a SELECT statement i.e. Symbol(b). - From this point on , we need to remember Symbol(b) as the source alias, - and then try to find the column.

These sets are automatically initialized when the - instance of the derived class is created. This behavior can be modified by applying the - attribute to either the entire derived context - class, or to individual properties on the class. - The Entity Data Model backing the context can be specified in several ways. When using the Code First - approach, the properties on the derived context are used to build a model - by convention. The protected OnModelCreating method can be overridden to tweak this model. More - control over the model used for the Model First approach can be obtained by creating a - explicitly from a and passing this model to one of the DbContext constructors. - When using the Database First or Model First approach the Entity Data Model can be created using the - Entity Designer (or manually through creation of an EDMX file) and then this model can be specified using - entity connection string or an object. - The connection to the database (including the name of the database) can be specified in several ways. - If the parameterless DbContext constructor is called from a derived context, then the name of the derived context - is used to find a connection string in the app.config or web.config file. If no connection string is found, then - the name is passed to the DefaultConnectionFactory registered on the class. The connection - factory then uses the context name as the database name in a default connection string. (This default connection - string points to .\SQLEXPRESS on the local machine unless a different DefaultConnectionFactory is registered.) - Instead of using the derived context name, the connection/database name can also be specified explicitly by - passing the name to one of the DbContext constructors that takes a string. The name can also be passed in - the form "name=myname", in which case the name must be found in the config file or an exception will be thrown. - Note that the connection found in the app.config or web.config file can be a normal database connection - string (not a special Entity Framework connection string) in which case the DbContext will use Code First. - However, if the connection found in the config file is a special Entity Framework connection string, then the - DbContext will use Database/Model First and the model specified in the connection string will be used. - An existing or explicitly created DbConnection can also be used instead of the database/connection name. - A can be applied to a class derived from DbContext to set the - version of conventions used by the context when it creates a model. If no attribute is applied then the - latest version of conventions will be used. - - - - - Interface implemented by objects that can provide an instance. - The class implements this interface to provide access to the underlying - ObjectContext. - - - - - Gets the object context. - - The object context. - - - - Constructs a new context instance using conventions to create the name of the database to - which a connection will be made.

The default - implementation of this method does nothing, but it can be overridden in a derived class - such that the model can be further configured before it is locked down. - - - Typically, this method is called only once when the first instance of a derived context - is created. The model for that context is then cached and is for all further instances of - the context in the app domain. This caching can be disabled by setting the ModelCaching - property on the given ModelBuidler, but note that this can seriously degrade performance. - More control over caching is provided through use of the DbModelBuilder and DbContextFactory - classes directly. - - The builder that defines the model for the context being created. - - - - Internal method used to make the call to the real OnModelCreating method. - - The model builder. - - - - Returns a DbSet instance for access to entities of the given type in the context, - the ObjectStateManager, and the underlying store. - - - See the DbSet class for more details. - - The type entity for which a set should be returned. - A set for the given entity type. - - - - Returns a non-generic DbSet instance for access to entities of the given type in the context, - the ObjectStateManager, and the underlying store. - - The type of entity for which a set should be returned. - A set for the given entity type. - - See the DbSet class for more details. - - - - - Saves all changes made in this context to the underlying database. - - The number of objects written to the underlying database. - Thrown if the context has been disposed. - - - - Asynchronously saves all changes made in this context to the underlying database. - - - Multiple active operations on the same context instance are not supported.

To find out the - generated view we go to the ObjectItemCollection and see if it is not-null. If the ObjectItemCollection - is non-null, we get the view generation assemblies that it might have cached during the - Object metadata discovery.If there are no view generation assemblies we switch to the - runtime view generation strategy. If there are view generation assemblies, we get the list and - go through them and see if there are any assemblies that are there from which we have not already loaded - the views. We collect the views from assemblies that we have not already collected from earlier. - If the ObjectItemCollection is null and we are in the view generation mode, that means that - the query or update is issued from the Value layer and this is the first time view has been asked for. - The compile time view gen for value layer queries will work for very simple scenarios. - If the users wants to get the performance benefit, they should call MetadataWorkspace.LoadFromAssembly. - At this point we go through the referenced assemblies of the entry assembly( this wont work for Asp.net - or if the viewgen assembly was not referenced by the executing application). - and try to see if there were any view gen assemblies. If there are, we collect the views for all extents. - Once we have all the generated views gathered, we try to get the view for the extent passed in. - If we find one we will return it. If we can't find one an exception will be thrown. - If there were no view gen assemblies either in the ObjectItemCollection or in the list of referenced - assemblies of calling assembly, we change the mode to runtime view generation and will continue to - be in that mode for the rest of the lifetime of the mapping item collection. - - - - - The class loads an MSL file into memory and exposes CSMappingMetadata interfaces. - The primary consumers of the interfaces are view genration and tools. - - - For Example if conceptually you could represent the CS MSL file as following - --Mapping - --EntityContainerMapping ( CNorthwind-->SNorthwind ) - --EntitySetMapping - --EntityTypeMapping - --TableMappingFragment - --EntityKey - --ScalarPropertyMap ( CMemberMetadata-->SMemberMetadata ) - --ScalarPropertyMap ( CMemberMetadata-->SMemberMetadata ) - --DiscriminatorProperyMap ( constant value-->SMemberMetadata ) - --EntityTypeMapping - --TableMappingFragment - --EntityKey - --ScalarPropertyMap ( CMemberMetadata-->SMemberMetadata ) - --ComplexPropertyMap - --ComplexTypeMap - --ScalarPropertyMap ( CMemberMetadata-->SMemberMetadata ) - --ScalarProperyMap ( CMemberMetadata-->SMemberMetadata ) - --DiscriminatorProperyMap ( constant value-->SMemberMetadata ) - --AssociationSetMapping - --AssociationTypeMapping - --TableMappingFragment - --EndPropertyMap - --ScalarPropertyMap ( CMemberMetadata-->SMemberMetadata ) - --ScalarProperyMap ( CMemberMetadata-->SMemberMetadata ) - --EndPropertyMap - --ScalarPropertyMap ( CMemberMetadata-->SMemberMetadata ) - --EntityContainerMapping ( CMyDatabase-->SMyDatabase ) - --CompositionSetMapping - --CompositionTypeMapping - --TableMappingFragment - --ParentEntityKey - --ScalarPropertyMap ( CMemberMetadata-->SMemberMetadata ) - --ScalarPropertyMap ( CMemberMetadata-->SMemberMetadata ) - --EntityKey - --ScalarPropertyMap ( CMemberMetadata-->SMemberMetadata ) - --ScalarPropertyMap ( CMemberMetadata-->Constant value ) - --ComplexPropertyMap - --ComplexTypeMap - --ScalarPropertyMap ( CMemberMetadata-->SMemberMetadata ) - --DiscriminatorProperyMap ( constant value-->SMemberMetadata ) - --ScalarPropertyMap ( CMemberMetadata-->Constant value ) - The CCMappingSchemaLoader loads an Xml file that has a conceptual structure - equivalent to the above example into in-memory data structure in a - top-dwon approach. - - - The loader uses XPathNavigator to parse the XML. The advantage of using XPathNavigator - over DOM is that it exposes the line number of the current xml content. - This is really helpful when throwing exceptions. Another advantage is - - - - - Public constructor. - For Beta2 we wont support delay loading Mapping information and we would also support - only one mapping file for workspace. - - - - - Dictionary to keep the list of all scalar member mappings - - - - The LoadMappingSchema method loads the mapping file and initializes the - MappingSchema that represents this mapping file. - For Beta2 atleast, we will support only one EntityContainerMapping per mapping file. - - - - - The method loads the child nodes for the root Mapping node - into the internal datastructures. - - - - - The method loads and returns the EntityContainer Mapping node. - - - - - The method loads the child nodes for the EntityContainer Mapping node - into the internal datastructures. - - - - - Validates that collocated association sets are consistently mapped for each entity set (all operations or none).

Ensuring a consistent ordering is important to avoid deadlocks - between two clients because it means locks are acquired in the same order where possible. The ordering criteria are as - follows (and are partly implemented in the CompareToType method).

This is an arbitrary criteria. - - The kind of operator (insert, update, delete). See for details of the ordering. - - The target of the modification (table for dynamic, set for function). - - Primary key for the modification (table key for dynamic, entity keys for function). - If it is not possible to differentiate between two commands (e.g., where the user is inserting entities with server-generated - primary keys and has not given explicit values), arbitrary ordering identifiers are assigned to the commands to - ensure CompareTo is well-behaved (doesn't return 0 for different commands and suggests consistent ordering). - - - - - Gets all identifiers (key values basically) generated by this command.

Flatten unions contained as left children of LOJs: LOJ(A, Union(B, C)) -> LOJ(A, B, C). - 2. Rewrite flat LOJs into nested LOJs. The nesting is determined by FKs between right cell table PKs. - Example: if we have an LOJ(A, B, C, D) and we know there are FKs from C.PK and D.PK to B.PK, - we want to rewrite into this - LOJ(A, LOJ(B, C, D)). - 3. As a special case we also look into LOJ driving node (left most child in LOJ) and if it is an IJ, - then we consider attaching LOJ children to nodes inside IJ based on the same principle as above. - Example: LOJ(IJ(A, B, C), D, E, F) -> LOJ(IJ(LOJ(A, D), B, LOJ(C, E)), F) iff D has FK to A and E has FK to C. - This normalization enables FK-based join elimination in plan compiler, so for a query such as - "select e.ID from ABCDSet" we want plan compiler to produce "select a.ID from A" instead of - "select a.ID from A LOJ B LOJ C LOJ D". - - - - - A class that handles creation of cells from the meta data information. - - - - - Boolean members have a closed domain and are enumerated when domains are established i.e. (T, F) instead of (notNull). - Query Rewriting is exercised over every domain of the condition member.

These sub-expressions may map to query parameters (e.g. local variables), - to constants (e.g. literals 'new DateTime(2008, 1, 1)') or query sub-expression - (e.g. 'context.Products'). Parameter expressions are replaced with QueryParameterExpression - nodes. All other elements are swapped in place with either expanded expressions (for sub-queries) - or constants. Where the expression includes mutable state that may influence the translation - to a query, a Func(Of Boolean) delegate is returned indicating when a recompilation is necessary. - - - - - Performs funcletization on the given expression. Also returns a delegates that can be used - to determine if the entire tree needs to be recompiled. - - - - - Replaces context parameter (e.g. 'ctx' in CompiledQuery.Compile(ctx => ctx.Products)) with constant - containing the object context. - - - - - Returns a function indicating whether the given expression and all of its children satisfy the - 'localCriterion'. - - - - - Determines whether the node may be evaluated locally and whether - it is a constant.

Queries and lambda expressions are expanded - inline. All other values become simple constants. - - - - - Gets the appropriate LINQ expression for an inline ObjectQuery instance. - - - - - Replaces expression patterns produced by the compiler with approximations - used in query translation. For instance, the following VB code: - x = y - becomes the expression - Equal(MethodCallExpression(Microsoft.VisualBasic.CompilerServices.Operators.CompareString(x, y, False), 0) - which is normalized to - Equal(x, y) - Comment convention: - CODE(Lang): _VB or C# coding pattern being simplified_ - ORIGINAL: _original LINQ expression_ - NORMALIZED: _normalized LINQ expression_ - - - - - If we encounter a MethodCallExpression, we never need to lift to lift to null. This capability - exists to translate certain patterns in the language. In this case, the user (or compiler) - has explicitly asked for a method invocation (at which point, lifting can no longer occur). - - - - - Gets a dictionary mapping from LINQ expressions to matched by those expressions.

Used - by the ObjectStateManager. - - - - - Add a DataContractAttribute to the proxy type, based on one that may have been applied to the base type. - - - From http://msdn.microsoft.com/en-us/library/system.runtime.serialization.datacontractattribute.aspx: A data contract has two basic requirements: a stable name and a list of members. The stable name consists of the namespace uniform resource identifier (URI) and the local name of the contract. By default, when you apply the DataContractAttribute to a class, it uses the class name as the local name and the class's namespace (prefixed with "http://schemas.datacontract.org/2004/07/") as the namespace URI. You can override the defaults by setting the Name and Namespace properties. You can also change the namespace by applying the ContractNamespaceAttribute to the namespace. Use this capability when you have an existing type that processes data exactly as you require but has a different namespace and class name from the data contract. By overriding the default values, you can reuse your existing type and have the serialized data conform to the data contract. - The first attempt at WCF serialization of proxies involved adding a DataContractAttribute to the proxy type in such a way so that the name and namespace of the proxy's data contract matched that of the base class. This worked when serializing proxy objects for the root type of the DataContractSerializer, but not for proxy objects of types derived from the root type. Attempting to add the proxy type to the list of known types failed as well, since the data contract of the proxy type did not match the base type as intended. This was due to the fact that inheritance is captured in the data contract. So while the proxy and base data contracts had the same members, the proxy data contract differed in that is declared itself as an extension of the base data contract. So the data contracts were technically not equivalent. The approach used instead is to allow proxy types to have their own DataContract. Users then have at least two options available to them. The first approach is to add the proxy types to the list of known types. The second approach is to implement an IDataContractSurrogate that can map a proxy instance to a surrogate that does have a data contract equivalent to the base type (you could use the base type itself for this purpose). While more complex to implement, it allows services to hide the use of proxies from clients.

ColumnMaps are produced as part of the PlanCompiler - module of the bridge, and are consumed by the Execution phase of the bridge. - * Simple (scalar) columns (and UDTs) are represented by a SimpleColumnMap - * Record type columns are represented by a RecordColumnMap - * A nominal type instance (that supports inheritance) is usually represented - by a PolymorphicColumnMap - this polymorphicColumnMap contains information - about the type discriminator (assumed to be a simple column), and a mapping - from type-discriminator value to the column map for the specific type - * The specific type for nominal types is represented by ComplexTypeColumnMap - for complextype columns, and EntityColumnMap for entity type columns. - EntityColumnMaps additionally have an EntityIdentity that describes - the entity identity. The entity identity is logically just a set of keys - (and the column maps), plus a column map that helps to identify the - the appropriate entity set for the entity instance - * Refs are represented by a RefColumnMap. The RefColumnMap simply contains an - EntityIdentity - * Collections are represented by either a SimpleCollectionColumnMap or a - DiscriminatedCollectionColumnMap. Both of these contain a column map for the - element type, and an optional list of simple columns (the keys) that help - demarcate the elements of a specific collection instance. - The DiscriminatedCollectionColumnMap is used in scenarios when the containing - row has multiple collections, and the different collection properties must be - differentiated. This differentiation is achieved via a Discriminator column - (a simple column), and a Discriminator value. The value of the Discriminator - column is read and compared with the DiscriminatorValue stored in this map - to determine if we're dealing with the current collection. - NOTE: - * Key columns are assumed to be SimpleColumns. There may be more than one key - column (applies to EntityColumnMap and *CollectionColumnMap) - * TypeDiscriminator and Discriminator columns are also considered to be - SimpleColumns. There are singleton columns. - It is the responsibility of the PlanCompiler phase to produce the right column - maps. - The result of a query is always assumed to be a collection.

The specified Var is a valid ParameterVar in the IQT Command being converted: - This resolves simply to ParameterRefExpression. A Parameter that corresponds to the ParameterVar - is declared on the CQT DbCommandTree is this has not already been done. - 2. The specified Var is a ComputedVar that is defined locally to the Op being visited. In this case - The DbExpression produced by converting the VarDefOp that defines the Var is returned. - 3. Otherwise, the Var must have been brought into scope because the DbExpression that logically produces it is - being used in a DbExpressionBinding which is currently in scope. Each RelOpInfo on the ExpressionBindingScopes stack - is asked to resolve the Var, if one of the RelOpInfo scopes is tracking the Var it will construct an appropriate combination - of DbVariableReferenceExpression and PropertyRefExpressions that are sufficient to logically reference the Var. - If none of the 3 above conditions are satisfied then the Var is unresolvable in the CQT being constructed and - the original IQT Command must be considered invalid for the purposes of this conversion. - - The IQT Var to resolve - The CQT DbExpression to which the specified Var resolves - - - - Asserts that the specified Node has exactly 2 child Nodes - - The Node on which to Assert - - - - A SoftCastOp is intended to be used only for promotion (and/or equivalence) - and should be ignored in the CTree - - the softcast Op - the node - - - - Generates a name for the specified Var. - If the Var has a name (TryGetName), then we use the name to look up - the right alias generator, and get a column name from the alias generator - Otherwise, we simply get a name from the default alias generator - - the var in question - map to identify the appropriate alias generator - the default alias generator - list of already used names - - - - Called by both Visit(ProjectOp) and VisitSetOpArgument to create a DbProjectExpression - based on the RelOpInfo of the projection input and the set of projected Vars. - Note: - The projected Vars must have already been brought into scope (by one of the - methods such as EnterExpressionBinding, EnterVarDefScope, etc) before this method - is called, or the projected Vars will not be successfully resolved. - Both Visit(ProjectOp) and VisitSetOpArgument do this" - 1.

For non-record sourceTypes, this should consist of a single column that logically constitutes the entire 'table' - A VarInfoList containing VarInfo instances that correctly track the Var or Vars produced by the targetTable, in accordance with the shape of the sourceType - - - - Translate UnnestOp which is assumed (at this stage) to wrap a native ScalarOp - that returns a collection (e.g. a table-valued function node). - - - - - Builds up an "empty" projection over the input node. Well, in reality, we build - up a dummy projection node - which simply selects out some constant (which - is never used). This is useful in scenarios where the outputs are - uninteresting, but the input row count is - - the relOp node - - - - Build up a Project Op with exactly the Vars that we want. If the input is - a Project already, piggyback on it, and get the Vars we want. Otherwise, - create a new ProjectOp, and define the specified Vars - Note that the ProjectOp's output (element) type will be a record with the fields - in exactly the order specified by the projectionVars argument - - the input relOpNode to cap with a Project - List of vars we are interested in - A ProjectOp that produces the right set of Vars - - - - Massages the input to a join node. - If the input is a Filter(ScanTable), we throw in a dummy project over - this input. This projectOp simply looks at the "referenced" columns of - the table, and uses those as the projection Vars - Otherwise, sqlgen does not really know which columns are referenced, and - ends up adding a projection with all columns of the table. - NOTE: We may want to do this for Apply as well - - one of the inputs to the join node - RelopInfo for the transformed input - - - - Called by all Visitor pattern method that handle binary JoinOps (Inner, FullOuter, LeftOuter) - - The IQT Node that references the JoinOp - The CQT DbExpressionKind that represents the type of join to create - - - - Called by both CrossApply and OuterApply visitor pattern methods - command handling of both types of Apply operation - - The Node that references the ApplyOp - The CQT DbExpressionKind that corresponds to the ApplyOp (DbExpressionKind.CrossApply for CrossApplyOp, DbExpressionKind.OuterApply for OuterApplyOp) - A new CqtResult containing a DbApplyExpression with the correct ApplyType - - - - Called by VisitSetOp to convert each argument. - Determines whether a column-reordering projection should be applied to - the argument, and applies that projection if necessary during conversion - to a DbExpression.

If the child is a ProjectOp, - then we simply piggyback on the ProjectOp method, but with our list of Vars. - Otherwise, we visit the child, and then create a DbProjectExpression above it. - The reason we special case the first scenario is because we do not want to add - an extra Project over a Project-over-Sort expression tree. This causes bad - problems later down the line - - the PhysicalProjectOp - current subtree - the CQT expression corresponding to this subtree - - - - The VarInfo class tracks how a single IQT Var should be referenced in terms of CQT Expressions. - The tracked Var must have been introduced by an IQT RelOp that was converted to a DbExpression that - is subsequently used in a DbExpressionBinding, otherwise the Var is either a ParameterVar or a locally - defined Var, which are tracked by the parameters collection of the Command and the VarDefScope - class, respectively. - An IQT Var that is tracked by a VarInfo instance is reachable in the following way: - 1. By a DbVariableReferenceExpression that references the Variable of the DbExpressionBinding that contains the DbExpression that logically publishes the IQT Var. - This is tracked by the PublisherName property of the RelOpInfo class, which is used to track Vars brought into scope by a DbExpressionBinding. - Without an enclosing RelOpInfo, the VarInfo is unbound and cannot be used to instantiate a CQT expression tree that is the equivalent of a VarRef of the IQT Var) - 2. By zero or more PropertyRefExpressions starting with a property of the DbVariableReferenceExpression created in step 1. - These PropertyRefExpressions are introduced on top of the DbVariableReferenceExpression because of Join or ApplyExpressions that - occur in the CQT between the expression that publishes the Var and the expression higher in the tree that contains a VarRefOp - to the IQT Var that must be resolved to a CQT DbExpression. In such cases the DbExpression that logically publishes - the IQT Var will have a record return Type. - The required property names are tracked, in order, in the PropertyPath property of this class. - The PrependProperty method is used to update the DbPropertyExpression path required to reach - the DbVariableReferenceExpression when the referenced Variable becomes part of such a record-typed output. - - - - - Constructs a new VarInfo instance that tracks the specified Var. - - The IQT Var that this VarInfo instance should track. - - - - Adds a property name to the beginning of the property path for this VarInfo instance. - Each time a new record structure is constructed on top of the expression that logically - publishes this var, another DbPropertyExpression is required around the DbVariableReferenceExpression used - to reach the Var in the CQT. Each new DbPropertyExpression must be added immediately around the - DbVariableReferenceExpression, with previous PropertyExpressions now referring to the new DbPropertyExpression. - Therefore the new property name added by this method is inserted at the start of the property path. - See the Visit methods for the Join/ApplyOps for examples of using this method to adjust the property path. - - The new property name to insert at the start of the property path for the Var tracked by this VarInfo instance - - - - Gets the Var tracked by this VarInfo instance - - - - - Gets the names, in order of use, that should be used to build DbPropertyExpression around an initial DbVariableReferenceExpression in order to build a DbExpression subtree that correctly references the tracked IQT Var - - - - - Groups a set of VarInfo instances together and allows certain operations (Bind/Unbind/PrependProperty) - to be performed on all instances in the VarInfoList with a single call. - - - - - Constructs a new, empty VarInfoList. - - - - - Constructs a new VarInfoList that contains the specified VarInfo instances. - - - - - Prepends the specified property name to the property path of all VarInfo instances in this list. - - - - - Attempts to retrieve the VarInfo instance that tracks the specified IQT Var, if it is contained by this VarInfoList. - - The required IQT Var - Contains the VarInfo instance that tracks the specified Var if this method returns true - True if this list contains a VarInfo instance that tracks the specified Var; otherwise false - - - - IqtVarScope is used to represent one or more IQT Vars that are currently in scope and can be mapped to a corresponding CQT DbExpression subtree. - - - - - Attempts to resolve the specified IQT Var by building or mapping to a CQT DbExpression subtree.

Even in this case, its not enough to take - the keys, and treat them as the keys of the union-all. What we’ll need to - do is to add a “branch” discriminator constant for each branch of the - union-all, and use this as the prefix for the keys. - For example, if I had: - Select c1, c2, c3... from ... - Union all - Select d1, d2, d3... from ... - And for the sake of argument, lets say that {c2} and {d2} are the keys of - each of the branches. What you’ll need to do is to translate this into - Select 0 as bd, c1, c2, c3... from ... - Union all - Select 1 as bd, d1, d2, d3... from ... - And then treat {bd, c2/d2} as the key of the union-all - Case 1: (actually, a subcase of Case 0): - Now, if the keys don’t align, then we can simply take the union of the - corresponding positions, and make them all the keys (we would still need - the branch discriminator) - Case 2: - Finally, if you need to “pull” up keys from either of the branches, it is - possible that the branches get out of whack. We will then need to push up - the keys (with nulls if the other branch doesn’t have the corresponding key) - into the union-all. (We still need the branch discriminator). - Now, unfortunately, whenever we've got polymorphic entity types, we'll end up - in case 2 way more often than we really want to, because when we're pulling up - keys, we don't want to reason about a caseop (which is how polymorphic types - wrap their key value). - To simplify all of this, we: - (1) Pulling up the keys for both branches of the UnionAll, and computing which - keys are in the outputs and which are missing from the outputs. - (2) Accumulate all the missing keys. - (3) Slap a projectOp around each branch, adding a branch discriminator - var and all the missing keys. When keys are missing from a different - branch, we'll construct null ops for them on the other branches. If - a branch already has a branch descriminator, we'll re-use it instead - of constructing a new one. (Of course, if there aren't any keys to - add and it's already including the branch discriminator we won't - need the projectOp) - - the UnionAllOp - current subtree - - - - A nested propertyref describes a nested property access - think "a.b.c" - - - - - Basic constructor. - Represents the access of property "propertyRef" within property "property" - - the inner property - the outer property - - - - Overrides the default equality function.

Does all the hard work of processing - - - - - is the node a NestOp node? - - - - - Not Supported common processing - For all those cases where we don't intend to support - a nest operation as a child, we have this routine to - do the work. - - - - - Follow the VarRef chain to the defining var - - - - - Update the replacement Var map with the vars from the pulled-up - operation; the shape is supposed to be identical, so we should not - have more vars on either side, and the order is guaranteed to be - the same. - - - - - Replace a list of sortkeys *IN-PLACE* with the corresponding "mapped" Vars - - sortkeys - the mapping info for Vars - - - - Produce a "mapped" sequence of the input Var sequence - based on the supplied - map - - input var sequence - var->var map - the mapped var sequence - - - - Produce a "mapped" varList - - - - - Produce a "mapped" varVec - - - - - VarDefOp - Essentially, maintains m_varRefMap, adding an entry for each VarDef that has a - VarRef on it. - - - - - VarRefOp - - - When we remove the UnnestOp, we are left with references to it's column vars that - need to be fixed up; we do this by creating a var replacement map when we remove the - UnnestOp and whenever we find a reference to a var in the map, we replace it with a - reference to the replacement var instead; - - - - - We don't yet support nest pullups over Case - - - - - The input to Exists is always a ProjectOp with a single constant var projected. - If the input to that ProjectOp contains nesting, it may end up with additional outputs after being - processed. If so, we clear out those additional outputs. - - - - - Default RelOp processing: - We really don't want to allow any NestOps through; just fail if we don't have - something coded. - - - - - ApplyOp/JoinOp common processing - - - If one of the inputs to any JoinOp/ApplyOp is a NestOp, then the NestOp - can be pulled above the join/apply if every input to the join/apply has - a key(s). The keys of the NestOp are augmented with the keys of the - other join inputs: - JoinOp/ApplyOp(NestOp(X, ...), Y) => NestOp(JoinOp/ApplyOp(X, Y), ...) - In addition, if the NestOp is on a 'nullable' side of a join (i.e. right side of - LeftOuterJoin/OuterApply or either side of FullOuterJoin), the driving node - of that NestOp (X) is capped with a project with a null sentinel and - the dependant collection nodes (the rest of the NestOp children) - are filtered based on that sentinel: - LOJ/OA/FOJ (X, NestOp(Y, Z1, Z2, ..ZN)) => NestOp( LOJ/OA/FOJ (X, PROJECT (Y, v = 1)), FILTER(Z1, v!=null), FILTER(Z2, v!=null), ...

FILTER(ZN, v!=null)) - Also, FILTER(Zi, v != null) may be transformed to push the filter below any NestOps. - The definitions for collection vars corresponding to the filtered collection nodes (in m_definingNodeMap) - are also updated to filter based on the sentinel. - Requires: Every input to the join/apply must have a key. - - - - - Applies a IsNotNull(sentinelVar) filter to the given node. - The filter is pushed below all MultiStremNest-s, because this part of the tree has - already been visited and it is expected that the MultiStreamNests have bubbled up - above the filters. - - - - - Input => Filter(input, Ref(var) is not null) - - - - - ApplyOp common processing - - - - - DistinctOp - - - The input to a DistinctOp cannot be a NestOp – that would imply that - we support distinctness over collections - which we don’t. - - - - - FilterOp - - - If the input to the FilterOp is a NestOp, and if the filter predicate - does not reference any of the collection Vars of the nestOp, then the - FilterOp can be simply pushed below the NestOp: - Filter(Nest(X, ...), pred) => Nest(Filter(X, pred), ...) - Note: even if the filter predicate originally referenced one of the - collection vars, as part of our bottom up traversal, the appropriate - Var was replaced by a copy of the source of the collection. So, this - transformation should always be legal. - - - - - GroupByOp - - - At this point in the process, there really isn't a way we should actually - have a NestOp as an input to the GroupByOp, and we currently aren't allowing - you to specify a collection as an aggregation Var or key, so if we find a - NestOp anywhere on the inputs, it's a NotSupported situation. - - - - - GroupByIntoOp - - - Transform the GroupByInto node into a Project over a GroupBy.

This may only occur if the original input to the - ProjectOp was an UnnestOp. - There are three cases to handle in ProjectOp: - (1) The input is not a NestOp; but the ProjectOp locally defines some Vars - as collections: - ProjectOp(X,{a,CollectOp(PhysicalProjectOp(Y)),b,...}) ==> MsnOp(ProjectOp'(X,{a,b,...}),Y) - ProjectOp(X,{a,VarRef(ref-to-collect-var-Y),b,...}) ==> MsnOp(ProjectOp'(X,{a,b,...}),copy-of-Y) - Where: - ProjectOp' is ProjectOp less any vars that were collection vars, plus - any additional Vars needed by the collection. - (2) The input is a NestOp, but the ProjectOp does not local define some Vars - as collections: - ProjectOp(MsnOp(X,Y,...)) => MsnOp'(ProjectOp'(X),Y,...) - Where: - ProjectOp' is ProjectOp plus any additional Vars needed by NestOp - (see NestOp.Outputs – except the collection vars) - MsnOp' should be MsnOp. Additionally, its Outputs should be enhanced - to include any Vars produced by the ProjectOp - (3) The combination of both (1) and (2) -- both the vars define a collection, - and the input is also a nestOp. we handle this by first processing Case1, - then processing Case2. - - - - - Helper method for . - - - - - Fold nested MultiStreamNestOps into one: - MSN(MSN(X,Y),Z) ==> MSN(X,Y,Z) - NOTE: It would be incorrect to merge NestOps from the non-driving node - into one nest op, because that would change the intent. Instead, - we let those go through the tree and wait until we get to the top - level PhysicalProject, when we'll use the ConvertToSingleStreamNest - process to handle them. - NOTE: We should never have three levels of nestOps, because we should - have folded the lower two together when we constructed one of them. - We also remove unreferenced collections, that is, if any collection is - not referred to by the top level-NestOp, we can safely remove it from - the merged NestOp we produce. - - - - - ProjectOp(X,{a,CollectOp(PhysicalProjectOp(Y)),b,...}) ==> MsnOp(ProjectOp'(X,{a,b,...}),Y) - ProjectOp(X,{a,VarRef(ref-to-collect-var-Y),b,...}) ==> MsnOp(ProjectOp'(X,{a,b,...}),copy-of-Y) - Remove CollectOps from projection, constructing a NestOp - over the ProjectOp. - - - - - If we're going to eat the ProjectNode, then we at least need to make - sure we remap any vars it defines as varRefs, and ensure that any - references to them are switched. - - - - - We need to make sure that we remap the column maps that we're pulling - up to point to the defined var, not it's reference. - - - - - Convert a CollectOp subtree (when used as the defining expression for a - VarDefOp) into a reasonable input to a NestOp. - - - There are a couple of cases that we handle here: - (a) PhysicalProject(X) ==> X - (b) PhysicalProject(Sort(X)) ==> Sort(X) - - the child of the CollectOp - the collectionVar being defined - where to append the new collectionInfo - where to append the collectionNode - a bit vector of external references of the physicalProject - a bit vector of collection vars - - - - Case 2 for ProjectOp: NestOp is the input: - ProjectOp(NestOp(X,Y,...)) => NestOp'(ProjectOp'(X),Y,...) - Remove collection references from the ProjectOp and pull the - NestOp over it, adding any outputs that the projectOp added. - The outputs are important here; expanding the above: - P{a,n}(N{x1,x2,x3,y}(X,Y)) => N{a,x1,x2,x3,y}(P{a,x1,x2,x3}(X),Y) - Strategy: - (1) Determine oldNestOpCollectionOutputs - (2) oldNestOpNonCollectionOutputs = oldNestOpOutputs - oldNestOpCollectionOutputs; - (3) oldProjectOpNonCollectionOutputs = oldProjectOpOutputs - oldNestOpCollectionOutputs - (4) oldProjectOpCollectionOutputs = oldProjectOpOutputs - oldProjectOpNonCollectionOutputs - (5) build a new list of collectionInfo's for the new NestOp, including - only oldProjectOpCollectionOutputs. - (6) leftCorrelationVars = vars that are defined by the left most child of the input nestOpNode - and used in the subtrees rooted at the other children of the input nestOpNode - (7) newProjectOpOutputs = oldProjectOpNonCollectionOutputs + oldNestOpNonCollectionOutputs + leftCorrelationVars - (8) newProjectOpChildren = .... - Of course everything needs to be "derefed", that is, expressed in the projectOp Var Ids. - (9) Set ProjectOp's input to NestOp's input - (10) Set NestOp's input to ProjectOp. - - - - - SetOp common processing - - - The input to an IntersectOp or an ExceptOp cannot be a NestOp – that - would imply that we support distinctness over collections - which - we don’t. - UnionAllOp is somewhat trickier. We would need a way to percolate keys - up the UnionAllOp – and I’m ok with not supporting this case for now. - - - - - SingleRowOp - SingleRowOp(NestOp(x,...)) => NestOp(SingleRowOp(x),...) - - - - - SortOp - - - If the input to a SortOp is a NestOp, then none of the sort - keys can be collection Vars of the NestOp – we don't support - sorts over collections. - - - - - ConstrainedSortOp - - - Push the ConstrainedSortOp onto the driving node of the NestOp: - ConstrainedSortOp(NestOp(X,Y,...)) ==> NestOp(ConstrainedSortOp(X),Y,...) - There should not be any need for var renaming, because the ConstrainedSortOp cannot - refer to any vars from the NestOp - - - - - Helper method used by Visit(ConstrainedSortOp, Node)and Visit(SortOp, Node). - It returns a NestBaseOp equivalent to the inputNestOp, only with the given sortKeys - prepended to the prefix sort keys already on the inputNestOp. - - - - - Helper method that given two lists of sort keys creates a single list of sort keys without duplicates. - First the keys from the first given list are added, then from the second one. - - - - - UnnestOp - - - Logically, the UnnestOp can simply be replaced with the defining expression - corresponding to the Var property of the UnnestOp. The tricky part is that - the UnnestOp produces a set of ColumnVars which may be referenced in other - parts of the query, and these need to be replaced by the corresponding Vars - produced by the defining expression. - There are essentially four cases: - Case 1: The UnnestOps Var is a UDT. Only the store can handle this, so we - pass it on without changing it. - Case 2: The UnnestOp has a Function as its input. This implies that the - store has TVFs, which it can Unnest, so we let it handle that and do - nothing. - Case 3: The UnnestOp Var defines a Nested collection. We'll just replace - the UnnestOp with the Input: - UnnestOp(VarDef(CollectOp(PhysicalProjectOp(input)))) => input - Case 4: The UnnestOp Var refers to a Nested collection from elsewhere. As we - discover NestOps, we maintain a var->PhysicalProject Node map. When - we get this case, we just make a copy of the PhysicalProject node, for - the referenced Var, and we replace the UnnestOp with it. - UnnestOp(VarDef(VarRef(v))) ==> copy-of-defining-node-for-v - Then, we need to update all references to the output Vars (ColumnVars) produced - by the Unnest to instead refer to the Vars produced by the copy of the subquery. - We produce a map from the Vars of the subquery to the corresponding vars of the - UnnestOp. We then use this map as we walk up the tree, and replace any references - to the Unnest Vars by the new Vars. - To simplify this process, as part of the ITreeGenerator, whenever we generate - an UnnestOp, we will generate a ProjectOp above it – which simply selects out - all Vars from the UnnestOp; and has no local definitions. This allows us to - restrict the Var->Var replacement to just ProjectOp. - - - - - Copies the given defining node for a collection var, but also makes sure to 'register' all newly - created collection vars (i.e. copied). - SQLBUDT #557427: The defining node that is being copied may itself contain definitions to other - collection vars. These defintions would be present in m_definingNodeMap. However, after we make a copy - of the defining node, we need to make sure to also put 'matching' definitions of these other collection - vars into m_definingNodeMap. - The dictionary collectionVarDefinitions (below) contains the copied definitions of such collection vars. - but without the wrapping PhysicalProjectOp. - Example: m_definingNodeMap contains (var1, definition1) and (var2, definintion2). - var2 is defined inside the definition of var1. - Here we copy definition1 -> definintion1'. - We need to add to m_definitionNodeMap (var2', definition2'). - definition2' should be a copy of definiton2 in the context of to definition1', - i.e. definition2' should relate to definition1' in same way that definition2 relates to definition1 - - - - - MultiStreamNestOp/SingleStreamNestOp common processing. - Pretty much just verifies that we didn't leave a NestOp behind. - - - - - PhysicalProjectOp - - - Tranformation: - PhysicalProjectOp(MultiStreamNestOp(...)) => PhysicalProjectOp(SortOp(...)) - Strategy: - (1) Convert MultiStreamNestOp(...) => SingleStreamNestOp(...) - (2) Convert SingleStreamNestOp(...) => SortOp(...) - (3) Fixup the column maps. - - - - - Build up a sort node above the nestOp's input - only if there - are any sort keys to produce - - - - - Build up the list of sortkeys. This list should comprise (in order): - - Any prefix sort keys (these represent sort operations on the - driving table, that were logically above the nest) - - The keys of the nest operation - - The discriminator column for the nest operation - - the list of postfix sort keys (used to represent nested collections) - Note that we only add the first occurrance of a var to the list; further - references to the same variable would be trumped by the first one. - - - - - convert MultiStreamNestOp to SingleStreamNestOp - - - A MultiStreamNestOp is typically of the form M(D, N1, N2, ..., Nk) - where D is the driver stream, and N1, N2 etc. represent the collections. - In general, this can be converted into a SingleStreamNestOp over: - (D+ outerApply N1) AugmentedUnionAll (D+ outerApply N2) ... - Where: - D+ is D with an extra discriminator column that helps to identify - the specific collection. - AugmentedUnionAll is simply a unionAll where each branch of the - unionAll is augmented with nulls for the corresponding columns - of other tables in the branch - The simple case where there is only a single nested collection is easier - to address, and can be represented by: - MultiStreamNest(D, N1) => SingleStreamNest(OuterApply(D, N1)) - The more complex case, where there is more than one nested column, requires - quite a bit more work: - MultiStreamNest(D, X, Y,...) => SingleStreamNest(UnionAll(Project{"1", D1...Dn, X1...Xn, nY1...nYn}(OuterApply(D, X)), Project{"2", D1...Dn, nX1...nXn, Y1...Yn}(OuterApply(D, Y)), ...)) - Where: - D is the driving collection - D1...Dn are the columns from the driving collection - X is the first nested collection - X1...Xn are the columns from the first nested collection - nX1...nXn are null values for all columns from the first nested collection - Y is the second nested collection - Y1...Yn are the columns from the second nested collection - nY1...nYn are null values for all columns from the second nested collection - - - - - "Normalize" each input to the NestOp. - We're now in the context of a MultiStreamNestOp, and we're trying to convert this - into a SingleStreamNestOp. - Normalization specifically refers to - - augmenting each input with a discriminator value (that describes the collection) - - removing the sort node at the root (and capturing this information as part of the sortkeys) - - the nestOp - the nestOp subtree - Discriminator Vars for each Collection input - SortKeys (postfix) for each Collection input - - - - 'Extend' a given input node to also project out an internal integer constant with the given value - - - - - Add a constant to a node.

Additionally, all structured types are replaced by "flat" - record types - where every field of the structured type is a scalar type. - Note that UDTs are not considered to be structured types. - At the end of this phase, - * there are no more nominal types in the tree - * there are no more nested record types in the tree - * No Var in the tree is of an structured type - * Additionally (and these follow from the statements above) - * There are no NewInstanceOp constructors in the tree - * There are no PropertyOp operators where the result is a structured type - This module uses information from the PropertyPushdown phase to "optimize" - structured type elimination. Essentially, if we can avoid producing pieces - of information that will be discarded later, then lets do that. - The general mechanism of type elimination is as follows. We walk up the tree - in a bottom up fashion, and try to convert all structured types into flattened - record types - type constructors are first converted into flat record constructors - and then dismantled etc. The barrier points - Vars - are all converted into - scalar types, and all intermediate stages will be eliminated in transition. - The output from this phase includes a ColumnMap - which is used later by - the execution model to produce results in the right form from an otherwise - flat query - Notes: This phase could be combined later with the PropertyPushdown phase - - - - - Eliminates all structural types from the query - - current compiler state - - inferred s-space keys for TVFs that are mapped to entities - - - - The real driver.

In such cases, we - build up a new ComputedVar (with an expected value of null), and use that - in place of the inner var. A subsequent stage will inspect the list of - new ComputedVars, and perform the appropriate fixups - - The VarMap to fixup - list of any new computedVars that are created - a new VarMap - - - - Flattens a SetOpVar (used in SetOps). Simply produces a list of - properties corresponding to each desired property - - - - - SoftCastOp - Visit the children first. - If this is an entity type, complextype or ref type, simply return the - visited child. (Rationale: These must be in the same type hierarchy; or - the earlier stages of query would have failed. And, we end up - using the same "flat" type for every type in the hierarchy) - If this is a scalar type, then simply return the current node - If this is a collection type, then create a new softcastOp over the input - (the collection type may have changed) - Otherwise, we're dealing with a record type. Since our earlier - definitions of equivalence required that equivalent record types must - have the same number of fields, with "promotable" types, and in the same - order; *and* since we asked for all properties (see PropertyPushdownHelper), - the input must be a NewRecordOp, whose fields line up 1-1 with our fields. - Build up a new NewRecordOp based on the arguments to the input NewRecordOp, - and build up SoftCastOps for any field whose type does not match - - - - - Removes or rewrites cast to enum or spatial type. - - - operator. - - Current node. - - Visited, possible rewritten . - - - - - Converts Constant enum value to its underlying type.

For example: - Case when b1 then e1 else e2 end - gets translated into: - RecordOp(case when b1 then e1.a else e2.a end, - case when b1 then e1.b else e2.b end, - ...) - The property extraction is optimized by producing only those properties - that have actually been requested. - - Node corresponding to the CaseOp - Information about the type - Set of properties desired - - - - CollectOp - Nothing much to do - simply update the result type - - the NestOp - corresponding node - new subtree - - - - ComparisonOp - If the inputs to the comparisonOp are Refs/records/entitytypes, then - we need to flatten these out.

Additionally, for nominal types, this module produces typeid - values that can be used later to interpret the input data stream. - The goal of this module is to load up information about type and entityset metadata - used in the ITree. This module is part of the "StructuredTypeElimination" phase, - and provides information to help in this process. - This module itself is broken down into multiple parts. - (*) Loading type information: We walk the query tree to identify all references - to structured types and entity sets - (*) Processing entitysets: We walk the list of entitysets, and assign ids to each - entityset. We also create a map of id->entityset metadata in this phase. - (*) Processing types: We then walk the list of types, and process each type. This, - in turn, is also broken into multiple parts: - * Populating the Type Map: we walk the list of reference types and add each of - them to our typeMap, along with their base types. - * TypeId assignment: We assign typeids to each nominal (complextype/entitytype). - This typeid is based on a dewey encoding. The typeid of a type is typically - the typeid of its supertype suffixed by the subtype number of this type within - its supertype. This encoding is intended to support easy type matching - later on in the query - both for exact (IS OF ONLY) and inexact (IS OF) matches. - * Type flattening: We then "explode"/"flatten" each structured type - refs, - entity types, complex types and record types. The result is a flattened type - where every single property of the resulting type is a primitive/scalar type - (Note: UDTs are considered to be scalar types). Additional information may also - be encoded as a type property. For example, a typeid property is added (if - necessary) to complex/entity types to help discriminate polymorphic instances. - An EntitySetId property is added to ref and entity type attributes to help - determine the entity set that a given entity instance comes from. - As part of type flattening, we keep track of additional information that allows - us to map easily from the original property to the properties in the new type - The final result of this processing is an object that contains: - * a TypeInfo (extra type information) for each structured type in the query - * a map from typeid value to type. To be used later by result assembly - * a map between entitysetid value and entityset. To be used later by result assembly - NOTE: StructuredTypeInfo is probably not the best name for this class, since - it doesn't derive from TypeInfo but rather manages a collection of them. - I don't have a better name, but if you come up with one change this. - - - - - Process Driver - - - structured types referenced in the query - entitysets referenced in the query - entity types that have "free-floating" entity constructors - information on optimized discriminator patterns for entity sets - helper for rel properties - which types need a null sentinel - - - - - Fills the StructuredTypeInfo instance from the itree provided. - - - referenced structured types - referenced entitysets - free-floating entityConstructor types - discriminator information for entity sets mapped using TPH pattern - helper for rel properties - - - - Gets the "single" entityset that stores instances of this type - - - - - Get the entitysetid value for a given entityset - - the entityset - entitysetid value - - - - Gets entity sets referenced by the query. - - entity sets - - - - Find the TypeInfo entry for a type.

For structured types, we return the entry in the typeInfoMap. - If we don't find one, and the typeInfoMap has already been populated, then we - assert - - the type to look up - the typeinfo for the type (null if we couldn't find one) - - - - Add a new entry to the entityTypeToSet map - - entity type - entityset producing this type - - - - Handle any relevant processing for entity sets - - referenced entitysets - free-floating entity constructor types - - - - Handle discriminator maps (determine which can safely be used in the query) - - - - - Assign ids to each entityset in the query - - referenced entitysets - - - - Process all types in the query - - referenced types - - - - Build up auxilliary information for each referenced type in the query - - - - - Tries to lookup custom discriminator map for the given type (applies to EntitySets with - TPH discrimination pattern) - - - - - Create a TypeInfo (if necessary) for the type, and add it to the TypeInfo map - - the type to process - - - - Add a new entry to the map. If an entry already exists, then this function - simply returns the existing entry. Otherwise a new entry is created. If - the type has a supertype, then we ensure that the supertype also exists in - the map, and we add our info to the supertype's list of subtypes - - New type to add - type discriminator map - The TypeInfo for this type - - - - Assigns typeids to each type in the map. - We walk the map looking only for "root" types, and call the function - above to process root types. All other types will be handled in that - function - - - - - Assign a typeid to a root type - - - - - Assigns typeids to each subtype of the current type. - Assertion: the current type has already had a typeid assigned to it. - - The current type - - - - Assign a typeid to a non-root type. - Assigns typeids to a non-root type based on a dewey encoding scheme. - The typeid will be the typeId of the supertype suffixed by a - local identifier for the type. - - the non-root type - position in the subtype list - - - - A type needs a type-id property if it is an entity type or a complex tpe that - has subtypes. - Coming soon: relax the "need subtype" requirement (ie) any entity/complex type will - have a typeid - - - - - A type needs a null-sentinel property if it is an row type that was projected - at the top level of the query; we capture that information in the preprocessor - and pass it in here. - - - - - The type needs an entitysetidproperty, if it is either an entity type - or a reference type, AND we cannot determine that there is only entityset - in the query that could be producing instances of this entity - - - - - "Explode" each type in the dictionary. (ie) for each type, get a flattened - list of all its members (including special cases for the typeid) - - - - - "Explode" a type. (ie) produce a flat record type with one property for each - scalar property (top-level or nested) of the original type. - Really deals with structured types, but also - peels off collection wrappers - - the type to explode - the typeinfo for this type (with the explosion) - - - - Type Explosion - simply delegates to the root type - - type info - - - - "Explode" a root type. (ie) add each member of the type to a flat list of - members for the supertype. - Type explosion works in a DFS style model. We first walk through the - list of properties for the current type, and "flatten" out the properties - that are themselves "structured". We then target each subtype (recursively) - and perform the same kind of processing. - Consider a very simple case: - Q = (z1 int, z2 date) - Q2: Q = (z3 string) -- Q2 is a subtype of Q - T = (a int, b Q, c date) - S: T = (d int) -- read as S is a subtype of T - The result of flattening T (and S) will be - (a int, b.z1 int, b.z2 date, b.z3 string, c date, d int) - - the root type to explode - - - - Helper for ExplodeType. - Walks through each member introduced by the current type, and - adds it onto the "flat" record type being constructed. - We then walk through all subtypes of this type, and process those as - well. - Special handling for Refs: we only add the keys; there is no - need to handle subtypes (since they won't be introducing anything - different) - - type in the type hierarchy - - - - Add the list of rel-properties for this type - - the type to process - - - - Create the flattened record type for the type. - Walk through the list of property refs, and creates a new field - (which we name as "F1", "F2" etc.) with the required property type. - We then produce a mapping from the original property (propertyRef really) - to the new property for use in later modules. - Finally, we identify the TypeId and EntitySetId property if they exist - - - - - Get the "new" type corresponding to the input type. For structured types, - we return the flattened record type. - For collections of structured type, we return a new collection type of the corresponding flattened - type. - For enum types we return the underlying type of the enum type. - For strong spatial types we return the union type that includes the strong spatial type. - For everything else, we return the input type - - the original type - the new type (if any) - - - - Get the datatype for a propertyRef. The only concrete classes that we - handle are TypeIdPropertyRef, and BasicPropertyRef. - AllPropertyRef is illegal here. - For BasicPropertyRef, we simply pick up the type from the corresponding - property. For TypeIdPropertyRef, we use "string" as the default type - or the discriminator property type where one is available. - - typeinfo of the current type - current property ref - the datatype of the property - - - - Get the root entity type for a type - - entity type - - - - Mapping from entitysetid-s to entitysets - - - - - Get a helper for rel properties - - - - - Finds the record (Row) types that we're projecting out of the query, and - ensures that we mark them as needing a nullable sentinel, so when we - flatten them later we'll have one added. - - - - - VarRefColumnMap - - - - - Recursively add any Row types to the list of types needing a sentinel. - - - - - Marks the given typeUsage as needing a null sentinel. - Call this method instead of calling Add over the HashSet directly, to ensure consistency. - - - - - The StructuredVarInfo class contains information about a structured type Var - and how it can be replaced. This is targeted towards Vars of complex/record/ - entity/ref types, and the goal is to replace all such Vars in this module. - - - - - Constructor - - new "flat" record type corresponding to the Var's datatype - List of vars to replace current Var - List of properties in the "flat" record type - Do the new vars include a var that represents a null sentinel either for this type or for any nested type - - - - Get the Var corresponding to a specific property - - the requested property - the corresponding Var - true, if the Var was found - - - - Initialize mapping from properties to the corresponding Var - - - - - Gets for this . Always - - . - - - - - The NewVars property of the VarInfo is a list of the corresponding - "scalar" Vars that can be used to replace the current Var. This is - mainly intended for use by other RelOps that maintain lists of Vars - - for example, the "Vars" property of ProjectOp and other similar - locations. - - - - - The Fields property is matched 1-1 with the NewVars property, and - specifies the properties of the record type corresponding to the - original VarType - - - - - Indicates whether any of the vars in NewVars 'derives' - from a null sentinel. For example, for a type that is a Record with two - nested records, if any has a null sentinel, it would be set to true. - It is used when expanding sort keys, to be able to indicate that there is a - sorting operation that includes null sentinels. This indication is later - used by transformation rules. - - - - - The NewType property describes the new "flattened" record type - that is a replacement for the original type of the Var - - - - - Returns the NewType wrapped in a TypeUsage - - - - - The list of all transformation rules to apply - - - - - A lookup table for built from all rules - The lookup table is an array indexed by OpType and each entry has a list of rules. - - - - - A lookup table for built only from ProjectRules - The lookup table is an array indexed by OpType and each entry has a list of rules. - - - - - A lookup table built only from rules that use key info - The lookup table is an array indexed by OpType and each entry has a list of rules. - - - - - A lookup table built only from rules that rely on nullability of vars and other rules - that may be able to perform simplificatios if these have been applied. - The lookup table is an array indexed by OpType and each entry has a list of rules. - - - - - A look-up table of rules that may cause modifications such that projection pruning may be useful - after they have been applied. - - - - - A look-up table of rules that may cause modifications such that reapplying the nullability rules - may be useful after they have been applied. - - - - - Apply the rules that belong to the specified group to the given query tree. - - - - - Apply the rules that belong to the specified rules table to the given query tree. - - - - is projection pruning required after the rule application - Whether any rule has been applied after which reapplying nullability rules may be useful - - - - Remap the given subree using the current remapper - - - - - Adds a mapping from oldVar to newVar - - - - - "Remap" an expression tree, replacing all references to vars in varMap with - copies of the corresponding expression - The subtree is modified *inplace* - it is the caller's responsibility to make - a copy of the subtree if necessary. - The "replacement" expression (the replacement for the VarRef) is copied and then - inserted into the appropriate location into the subtree. - Note: we only support replacements in simple ScalarOp trees.

Also return a dictionary of var refcounts (ie) - for each var encountered in the tree, determine the number of times it has - been seen - - current subtree - dictionary of var refcounts to fill in - - - - Get a mapping from Var->Expression for a VarDefListOp tree. This information - will be used by later stages to replace all references to the Vars by the - corresponding expressions - This function uses a few heuristics along the way. It uses the varRefMap - parameter to determine if a computed Var (defined by this VarDefListOp) - has been referenced multiple times, and if it has, it checks to see if - the defining expression is too big (> 100 nodes). This is to avoid - bloating up the entire query tree with too many copies. - - The varDefListOp subtree - ref counts for each referenced var - mapping from Var->replacement xpressions - - - - Builds a NULLIF expression (ie) a Case expression that looks like - CASE WHEN v is null THEN null ELSE expr END - where v is the conditionVar parameter, and expr is the value of the expression - when v is non-null - - null discriminator var - expression - - - - Shut off filter pushdown for this subtree - - - - - Is filter pushdown shut off for this subtree? - - - - - Given a list of vars try to get one that is of type Int32 - - - - - Callback function to invoke *before* rules are applied. - Calls the VarRemapper to update any Vars in this node, and recomputes - the nodeinfo - - - - - Callback function to invoke *before* rules are applied. - Calls the VarRemapper to update any Vars in the entire subtree - If the given node has a RelOp it is pushed on the relOp ancestors stack. - - - - - If the given node has a RelOp it is popped from the relOp ancestors stack. - - - - - Callback function to invoke *after* rules are applied - Recomputes the node info, if this node has changed - If the rule is among the rules after which projection pruning may be beneficial, - m_projectionPrunningRequired is set to true. - If the rule is among the rules after which reapplying the nullability rules may be beneficial, - m_reapplyNullabilityRules is set to true. - - - the rule that was applied - - - - Get the hash value for this subtree - - - - - Check to see if the current subtree is a scalar-op subtree (ie) does - the subtree only comprise of scalarOps? - Additionally, compute the number of non-leaf nodes (ie) nodes with at least one child - that are found in the subtree. Note that this count is approximate - it is only - intended to be used as a hint. It is the caller's responsibility to initialize - nodeCount to a sane value on entry into this function - And finally, if the varRefMap parameter is non-null, we keep track of - how often a Var is referenced within the subtree - The non-leaf-node count and the varRefMap are used by GetVarMap to determine - if expressions can be composed together - - root of the subtree - Ref counts for each Var encountered in the subtree - count of non-leaf nodes encountered in the subtree - true, if this node only contains scalarOps - - - - Whether any rule was applied that may have caused modifications such that projection pruning - may be useful - - - - - Whether any rule was applied that may have caused modifications such that reapplying - the nullability rules may be useful - - - - - Is it safe to use a null sentinel with any value? - It may not be safe if: - 1. The top most sort includes null sentinels. If the null sentinel is replaced with a different value - and is used as a sort key it may change the sorting results - 2. If any of the ancestors is Distinct, GroupBy, Intersect or Except, - because the null sentinel may be used as a key. - 3. If the null sentinel is defined in the left child of an apply it may be used at the right side, - thus in these cases we also verify that the right hand side does not have any Distinct, GroupBy, - Intersect or Except. - - - - - Available groups of rules, not necessarily mutually exclusive - - - - - The kind of type-id in use - - - - - A TypeId propertyref represents a reference to the TypeId property - of a type (complex type, entity type etc.) - - - - - Gets the default instance of this type - - - - - Friendly string for debugging. - - - - - This class is used as a Comparer for Types all through the PlanCompiler. - It has a pretty strict definition of type equality - which pretty much devolves - to equality of the "Identity" of the Type (not the TypeUsage). - NOTE: Unlike other parts of the query pipeline, record types follow - a much stricter equality condition here - the field names must be the same, and - the field types must be equal. - NOTE: Primitive types are considered equal, if their Identities are equal. This doesn't - take into account any of the facets that are represented external to the type (size, for instance). - Again, this is different from other parts of the query pipeline; and we're much stricter here - - - - - Is this a structured type? - Note: Structured, in this context means structured outside the server. - UDTs for instance, are considered to be scalar types - all WinFS types, - would by this argument, be scalar types. - - The type to check - true, if the type is a structured type - - - - Is this type a collection type? - - the current type - true, if this is a collection type - - - - Is this type an enum type? - - the current type - true, if this is an enum type - - - - Create a new collection type based on the supplied element type - - element type of the collection - the new collection type - - - - Kind of VarInfo - - - - - The VarInfo is of type. - - - - - The VarInfo is of type. - - - - - The VarInfo is of type. - - - - - The VarInfo map maintains a mapping from Vars to their corresponding VarInfo - It is logically a Dictionary - - - - - Default constructor - - - - - Create a new VarInfo for a structured type Var - - The structured type Var - "Mapped" type for v - List of vars corresponding to v - Flattened Properties - Do the new vars include a var that represents a null sentinel either for this type or for any nested type - the VarInfo - - - - Create a new VarInfo for a structured type Var where the newVars cannot include a null sentinel - - The structured type Var - "Mapped" type for v - List of vars corresponding to v - Flattened Properties - - - - Create a VarInfo for a collection typed Var - - The collection-typed Var - the new Var - the VarInfo - - - - Creates a var info for var variables of primitive or enum type. - - Current variable of primitive or enum type. - - The new variable replacing . - - - for . - - - - - Return the VarInfo for the specified var (if one exists, of course) - - The Var - the corresponding VarInfo - - - - This is a halper module for - The VarRefManager keeps track of the child-parent relationships in order to be able - to decide whether a given var is referenced by children on right-side relatives of a given node. - It is used in JoinElimination when deciding whether it is possible to eliminate the child table participating - in a left-outer join when there is a 1 - 0..1 FK relationship. - - - - - Constructs a new VarRefManager given a command. - - - - - Tracks the information that the given node is a parent of its children (one level only) - - - - - Determines whether any var from a given list of keys is referenced by any of defining node's right relatives, - with the exception of the relatives brunching at the given targetJoinNode. - - A list of vars to check for - The node considered to be the defining node - The relatives branching at this node are skipped - False, only it can determine that not a single var from a given list of keys is referenced by any of defining node's right relatives, with the exception of the relatives brunching at the given targetJoinNode. - - - - Checks whether the given node has references to any of the vars in the given VarVec. - It only checks the given node, not its children. - - The node to check - The list of vars to check for - The index of the node's subree from which this var is coming.

These sets are automatically initialized when the + instance of the derived class is created. This behavior can be modified by applying the + attribute to either the entire derived context + class, or to individual properties on the class. + The Entity Data Model backing the context can be specified in several ways. When using the Code First + approach, the properties on the derived context are used to build a model + by convention. The protected OnModelCreating method can be overridden to tweak this model. More + control over the model used for the Model First approach can be obtained by creating a + explicitly from a and passing this model to one of the DbContext constructors. + When using the Database First or Model First approach the Entity Data Model can be created using the + Entity Designer (or manually through creation of an EDMX file) and then this model can be specified using + entity connection string or an object. + The connection to the database (including the name of the database) can be specified in several ways. + If the parameterless DbContext constructor is called from a derived context, then the name of the derived context + is used to find a connection string in the app.config or web.config file. If no connection string is found, then + the name is passed to the DefaultConnectionFactory registered on the class. The connection + factory then uses the context name as the database name in a default connection string. (This default connection + string points to .\SQLEXPRESS on the local machine unless a different DefaultConnectionFactory is registered.) + Instead of using the derived context name, the connection/database name can also be specified explicitly by + passing the name to one of the DbContext constructors that takes a string. The name can also be passed in + the form "name=myname", in which case the name must be found in the config file or an exception will be thrown. + Note that the connection found in the app.config or web.config file can be a normal database connection + string (not a special Entity Framework connection string) in which case the DbContext will use Code First. + However, if the connection found in the config file is a special Entity Framework connection string, then the + DbContext will use Database/Model First and the model specified in the connection string will be used. + An existing or explicitly created DbConnection can also be used instead of the database/connection name. + A can be applied to a class derived from DbContext to set the + version of conventions used by the context when it creates a model.

The default + implementation of this method does nothing, but it can be overridden in a derived class + such that the model can be further configured before it is locked down. + + + Typically, this method is called only once when the first instance of a derived context + is created. The model for that context is then cached and is for all further instances of + the context in the app domain.

These sets are automatically initialized when the + instance of the derived class is created. This behavior can be modified by applying the + attribute to either the entire derived context + class, or to individual properties on the class. + The Entity Data Model backing the context can be specified in several ways. When using the Code First + approach, the properties on the derived context are used to build a model + by convention. The protected OnModelCreating method can be overridden to tweak this model. More + control over the model used for the Model First approach can be obtained by creating a + explicitly from a and passing this model to one of the DbContext constructors. + When using the Database First or Model First approach the Entity Data Model can be created using the + Entity Designer (or manually through creation of an EDMX file) and then this model can be specified using + entity connection string or an object. + The connection to the database (including the name of the database) can be specified in several ways. + If the parameterless DbContext constructor is called from a derived context, then the name of the derived context + is used to find a connection string in the app.config or web.config file. If no connection string is found, then + the name is passed to the DefaultConnectionFactory registered on the class. The connection + factory then uses the context name as the database name in a default connection string. (This default connection + string points to .\SQLEXPRESS on the local machine unless a different DefaultConnectionFactory is registered.) + Instead of using the derived context name, the connection/database name can also be specified explicitly by + passing the name to one of the DbContext constructors that takes a string. The name can also be passed in + the form "name=myname", in which case the name must be found in the config file or an exception will be thrown. + Note that the connection found in the app.config or web.config file can be a normal database connection + string (not a special Entity Framework connection string) in which case the DbContext will use Code First. + However, if the connection found in the config file is a special Entity Framework connection string, then the + DbContext will use Database/Model First and the model specified in the connection string will be used. + An existing or explicitly created DbConnection can also be used instead of the database/connection name. + A can be applied to a class derived from DbContext to set the + version of conventions used by the context when it creates a model. If no attribute is applied then the + latest version of conventions will be used. + + + + + Interface implemented by objects that can provide an instance. + The class implements this interface to provide access to the underlying + ObjectContext. + + + + + Gets the object context. + + The object context. + + + + Constructs a new context instance using conventions to create the name of the database to + which a connection will be made.

The latter case happens as part of default code generation when + a non-nullable property in the conceptual model is mapped to a nullable CLR type such as a string. + In such a case, the Entity Framework treats the property as non-nullable even though the CLR would + allow null to be set. + There is no good reason to set a non-nullable CLR type as nullable in the object model and this + should not be done even though the attribute allows it. + + + true if this can have a null value; otherwise, false. + + Thrown if the setter is called when the EdmProperty instance is in ReadOnly state + + + Gets the type name of the property. + The type name of the property. + + + + Gets the default value for this . + + + The default value for this . + + Thrown if the setter is called when the EdmProperty instance is in ReadOnly state + + + Gets whether the property is a collection type property. + true if the property is a collection type property; otherwise, false. + + + Gets whether this property is a complex type property. + true if this property is a complex type property; otherwise, false. + + + Gets whether this property is a primitive type. + true if this property is a primitive type; otherwise, false. + + + Gets whether this property is an enumeration type property. + true if this property is an enumeration type property; otherwise, false. + + + Gets whether this property is an underlying primitive type. + true if this property is an underlying primitive type; otherwise, false. + + + Gets the complex type information for this property. + The complex type information for this property. + + + Gets the primitive type information for this property. + The primitive type information for this property. + + + Gets the enumeration type information for this property. + The enumeration type information for this property. + + + Gets the underlying primitive type information for this property. + The underlying primitive type information for this property. + + + Gets or sets the concurrency mode for the property. + The concurrency mode for the property. + + + Gets or sets the database generation method for the database column associated with this property + The store generated pattern for the property. + + + Gets or sets the kind of collection for this model. + The kind of collection for this model. + + + Gets whether the maximum length facet is constant for the database provider. + true if the facet is constant; otherwise, false. + + + Gets or sets the maximum length of the property. + The maximum length of the property. + + + Gets or sets whether this property uses the maximum length supported by the provider. + true if this property uses the maximum length supported by the provider; otherwise, false. + + + Gets whether the fixed length facet is constant for the database provider. + true if the facet is constant; otherwise, false. + + + Gets or sets whether the length of this property is fixed. + true if the length of this property is fixed; otherwise, false. + + + Gets whether the Unicode facet is constant for the database provider. + true if the facet is constant; otherwise, false. + + + Gets or sets whether this property is a Unicode property. + true if this property is a Unicode property; otherwise, false. + + + Gets whether the precision facet is constant for the database provider. + true if the facet is constant; otherwise, false. + + + Gets or sets the precision of this property. + The precision of this property. + + + Gets whether the scale facet is constant for the database provider. + true if the facet is constant; otherwise, false. + + + Gets or sets the scale of this property. + The scale of this property. + + + + Class for representing an entity container + + + + + Returns an object by using the specified name for the entity set. + + + An object that represents the entity set that has the specified name. + + The name of the entity set that is searched for. + true to perform the case-insensitive search; otherwise, false. + + + + Returns an object by using the specified name for the entity set. + + true if there is an entity set that matches the search criteria; otherwise, false. + The name of the entity set that is searched for. + true to perform the case-insensitive search; otherwise, false. + + When this method returns, contains an object.
