Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.

The primary data structure representing the state/components used during relational query compilation.

This type is typically used by database providers (and other extensions). It is generally not used in application code.

Constructors

RelationalQueryCompilationContext(IModel, ISensitiveDataLogger, IEntityQueryModelVisitorFactory, IRequiresMaterializationExpressionVisitorFactory, ILinqOperatorProvider, IQueryMethodProvider, Type, Boolean)	This API supports the Entity Framework Core infrastructure and is not intended to be used directly from your code. This API may change or be removed in future releases.
RelationalQueryCompilationContext(QueryCompilationContextDependencies, ILinqOperatorProvider, IQueryMethodProvider, Boolean)	This API supports the Entity Framework Core infrastructure and is not intended to be used directly from your code. This API may change or be removed in future releases.
RelationalQueryCompilationContext(QueryCompilationContextDependencies, RelationalQueryCompilationContextDependencies, Boolean, Boolean, IReadOnlySet<String>)	Creates a new instance of the RelationalQueryCompilationContext class.
RelationalQueryCompilationContext(QueryCompilationContextDependencies, RelationalQueryCompilationContextDependencies, Boolean)	Creates a new instance of the RelationalQueryCompilationContext class.

Fields

QueryParameterPrefix

Prefix for all the query parameters generated during parameter extraction in query pipeline.

This property is typically used by database providers (and other extensions). It is generally not used in application code.

(Inherited from QueryCompilationContext)

Properties

ContextOptions	The ContextOptions to use during query compilation. (Inherited from QueryCompilationContext)
ContextType	The CLR type of derived DbContext to use during query compilation. (Inherited from QueryCompilationContext)
Dependencies	Dependencies for this service. (Inherited from QueryCompilationContext)
IgnoreAutoIncludes	A value indicating whether eager loaded navigations are ignored in this query. (Inherited from QueryCompilationContext)
IgnoreQueryFilters	A value indicating whether query filters are ignored in this query. (Inherited from QueryCompilationContext)
IsAsync	A value indicating whether it is async query. (Inherited from QueryCompilationContext)
IsAsyncQuery	Get a value indicating whether query that is being processed is asynchronous. (Inherited from QueryCompilationContext)
IsBuffering	A value indicating whether the underlying server query needs to pre-buffer all data. (Inherited from QueryCompilationContext)
IsIncludeQuery	The query has at least one Include operation. (Inherited from QueryCompilationContext)
IsLateralJoinSupported	True if the current provider supports SQL LATERAL JOIN.
IsPrecompiling	Indicates whether the query is being precompiled. (Inherited from QueryCompilationContext)
IsQueryBufferRequired	Gets a value indicating whether this query requires a query buffer. (Inherited from QueryCompilationContext)
IsTracking	Obsolete. A value indicating whether it is tracking query. (Inherited from QueryCompilationContext)
IsTrackingQuery	Gets a value indicating whether this is a tracking query. (Inherited from QueryCompilationContext)
LinqOperatorProvider	Gets the LINQ operator provider. (Inherited from QueryCompilationContext)
Logger	The query logger to use during query compilation. (Inherited from QueryCompilationContext)
MaxTableAliasLength	Max length of the table alias supported by provider.
Model	The model to use during query compilation. (Inherited from QueryCompilationContext)
NonNullableReferenceTypeParameters	Names of parameters which have non-nullable reference types. (Inherited from QueryCompilationContext)
ParametersToConstantize	Names of parameters on which Constant<T>(T) was used. Such parameters are later transformed into constants. This property is typically used by database providers (and other extensions). It is generally not used in application code. (Inherited from QueryCompilationContext)
ParametersToNotConstantize	Names of parameters on which Parameter<T>(T) was used. Such parameters are later not transformed into constants even when parameterized collection constantization is configured as the default. This property is typically used by database providers (and other extensions). It is generally not used in application code. (Inherited from QueryCompilationContext)
ParentQueryReferenceParameters	Gets the list of parameter names that represent reference to a parent query.
QueryAnnotations	Gets the query annotations. (Inherited from QueryCompilationContext)
QueryMethodProvider	Gets the query method provider.
QuerySourceMapping	Gets the query source mapping. (Inherited from QueryCompilationContext)
QuerySplittingBehavior	A value indicating the QuerySplittingBehavior configured for the query. If no value has been configured then SingleQuery will be used.
QueryTrackingBehavior	A value indicating QueryTrackingBehavior of the query. (Inherited from QueryCompilationContext)
RelationalDependencies	Relational provider-specific dependencies for this service.
SqlAliasManager	A manager for SQL aliases, capable of generate uniquified table aliases.
SupportsPrecompiledQuery	A value indicating whether the provider supports precompiled query. Default value is `false`. Providers that do support this feature should opt-in by setting this value to `true`. (Inherited from QueryCompilationContext)
Tags	The set of tags applied to this query. (Inherited from QueryCompilationContext)
TrackQueryResults	Gets a value indicating the default configured tracking behavior. (Inherited from QueryCompilationContext)
