Constructors

DeleteExpression(TableExpression, SelectExpression, ISet<String>)	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.
DeleteExpression(TableExpression, SelectExpression)	Creates a new instance of the DeleteExpression class.

Properties

NodeType	Gets the node type of this Expression.
SelectExpression	The select expression which is used to determine which rows to delete.
Table	The table on which the delete operation is being applied.
Tags	The list of tags applied to this DeleteExpression.
Type	Gets the static type of the expression that this Expression represents.

Methods

ApplyTags(ISet<String>)	Applies a given set of tags.
Equals(Object)	System.Linq.Expressions.Expression.Equals(System.Object)
GetHashCode()	System.Linq.Expressions.Expression.GetHashCode
Print(ExpressionPrinter)	Creates a printable string representation of 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.
Update(SelectExpression)	Creates a new expression that is like this one, but using the supplied children. If all of the children are the same, it will return this expression.
Update(TableExpression, SelectExpression)	Creates a new expression that is like this one, but using the supplied children. If all of the children are the same, it will return this expression.
