Constructors

SqlExpression(Type, RelationalTypeMapping)

Creates a new instance of the SqlExpression class.

Properties

NodeType	Gets the node type of this Expression.
Type	Gets the static type of the expression that this Expression represents.
TypeMapping	The RelationalTypeMapping associated with this expression.

Methods

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.
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.

Explicit Interface Implementations

IPrintableExpression.Print(ExpressionPrinter)

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