Remarks

This is a simple wrapper around a table and schema name. Instances of this type cannot be constructed by application or database provider code. If this is a problem for your application or provider, then please file an issue at github.com/dotnet/efcore.

Constructors

TableExpression(String, ITableBase, IReadOnlyDictionary<String,IAnnotation>)	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.
TableExpression(String, ITableBase)	Creates a new instance of the TableExpression class.

Properties

Alias	The alias assigned to this table source.
Alias	The alias assigned to this table source. (Inherited from TableExpressionBase)
Annotations	An indexed collection of annotations associated with this table expression. (Inherited from TableExpressionBase)
Name	The name of the table or view.
NodeType	(Inherited from TableExpressionBase)
Schema	The schema of the table or view.
Table	The ITableBase associated with this table or view.
Type	(Inherited from TableExpressionBase)

Methods

AddAnnotation(String, Object)	Adds an annotation to this object. Throws if an annotation with the specified name already exists. (Inherited from TableExpressionBase)
Clone()	Creates a new object that is a copy of the current instance.
Clone(String, ExpressionVisitor)	Creates a new object that is a copy of the current instance.
Clone(String, ExpressionVisitor)	Creates a new object that is a copy of the current instance. (Inherited from TableExpressionBase)
CreateWithAnnotations(IEnumerable<IAnnotation>)	Creates an object like this with specified annotations. (Inherited from TableExpressionBase)
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. (Inherited from TableExpressionBase)
GetAnnotations()	Gets all annotations on the current object. (Inherited from TableExpressionBase)
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. (Inherited from TableExpressionBase)
Print(ExpressionPrinter)	Creates a printable string representation of the given expression using ExpressionPrinter.
Print(ExpressionPrinter)	Creates a printable string representation of the given expression using ExpressionPrinter. (Inherited from TableExpressionBase)
PrintAnnotations(ExpressionPrinter)	Creates a printable string representation of annotations associated with the given expression using ExpressionPrinter. (Inherited from TableExpressionBase)
Quote()	System.Linq.Expressions.Expression.Quote
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. (Inherited from TableExpressionBase)
VisitChildren(ExpressionVisitor)	(Inherited from TableExpressionBase)
WithAlias(String)	Returns a copy of the current TableExpressionBase with the new provided alias.
WithAlias(String)	Returns a copy of the current TableExpressionBase with the new provided alias. (Inherited from TableExpressionBase)
WithAnnotations(IReadOnlyDictionary<String,IAnnotation>)	Creates an object like this with specified annotations. (Inherited from TableExpressionBase)

Explicit Interface Implementations

IPrintableExpression.Print(ExpressionPrinter)	Creates a printable string representation of the given expression using ExpressionPrinter. (Inherited from TableExpressionBase)
ITableBasedExpression.Table	The ITableBase associated with given table source, if any.

Extension Methods

UnwrapJoin(TableExpressionBase)

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