Definition

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)

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.
