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. |
CaseExpression(SqlExpression, IReadOnlyList<CaseWhenClause>) |
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. |
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 SqlExpression) |
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. |
Explicit Interface Implementations
