TableExpressionBase Class

Definition

An expression that represents a table source in a SQL tree.

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

Constructors

TableExpressionBase(String, IEnumerable<IAnnotation>)

Creates a new instance of the TableExpressionBase class.

TableExpressionBase(String, IReadOnlyDictionary<String,IAnnotation>)

Creates a new instance of the TableExpressionBase class.

TableExpressionBase(String)

Creates a new instance of the TableExpressionBase class.

Properties

Alias

The alias assigned to this table source.

Annotations

An indexed collection of annotations associated with this table expression.

NodeType

Gets the node type of this Expression.

Type

Gets the static type of the expression that this Expression represents.

Methods

AddAnnotation(String, Object)

Adds an annotation to this object. Throws if an annotation with the specified name already exists.

Clone(String, ExpressionVisitor)

Creates a new object that is a copy of the current instance.

CreateWithAnnotations(IEnumerable<IAnnotation>)

Creates an object like this with specified annotations.

Equals(Object) System.Linq.Expressions.Expression.Equals(System.Object)
FindAnnotation(String)

Gets the annotation with the given name, returning null if it does not exist.

GetAnnotations()

Gets all annotations on the current object.

GetHashCode() System.Linq.Expressions.Expression.GetHashCode
GetRequiredAlias()

This is an internal API that supports the Entity Framework Core infrastructure and not subject to the same compatibility standards as public APIs. It may be changed or removed without notice in any release. You should only use it directly in your code with extreme caution and knowing that doing so can result in application failures when updating to a new Entity Framework Core release.

Print(ExpressionPrinter)

Creates a printable string representation of the given expression using ExpressionPrinter.

PrintAnnotations(ExpressionPrinter)

Creates a printable string representation of annotations associated with the given expression using ExpressionPrinter.

Quote()

Quotes the expression; that is, returns an expression that, when evaluated, would construct an expression identical to this one. Used to generate code for precompiled queries, which reconstructs this expression.

VisitChildren(ExpressionVisitor)

Reduces the node and then calls the visitor delegate on the reduced expression. The method throws an exception if the node is not reducible.

WithAlias(String)

Returns a copy of the current TableExpressionBase with the new provided alias.

WithAnnotations(IReadOnlyDictionary<String,IAnnotation>)

Creates an object like this with specified annotations.

Explicit Interface Implementations

IPrintableExpression.Print(ExpressionPrinter)

Creates a printable string representation of the given expression using ExpressionPrinter.

Extension Methods

UnwrapJoin(TableExpressionBase)

If the given table is a JoinExpressionBase, returns the table it joins to. Otherwise, returns table.
