Constructors

CaseExpression(IReadOnlyList<CaseWhenClause>, SqlExpression)	Creates a new instance of the CaseExpression class which represents a searched CASE expression.
CaseExpression(SqlExpression, IReadOnlyList<CaseWhenClause>, SqlExpression)	Creates a new instance of the CaseExpression class which represents a simple CASE expression.

Properties

ElseResult	The value to return if none of the WhenClauses matches.
NodeType	(Inherited from SqlExpression)
Operand	The value to compare in WhenClauses.
Type	(Inherited from SqlExpression)
TypeMapping	The RelationalTypeMapping associated with this expression. (Inherited from SqlExpression)
WhenClauses	The list of CaseWhenClause to match Operand or evaluate condition to get result.

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.
Update(SqlExpression, IReadOnlyList<CaseWhenClause>, SqlExpression)	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.
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.
