RWDBSimpleCaseExpr represents a specialized type of RWDBExpr used to specify a simple SQL CASE
expression.
WHEN
expressions and an ELSE
expression, then is finally inserted into the SELECT
list. RWDBSimpleCaseExpr::RWDBSimpleCaseExpr | ( | const RWDBExpr & | input | ) |
Constructs an RWDBSimpleCaseExpr from input expression.
RWDBSimpleCaseExpr::RWDBSimpleCaseExpr | ( | const RWDBSimpleCaseExpr & | simpleCaseExpr | ) |
Copy constructor. The created RWDBSimpleCaseExpr shares an implementation with simpleCaseExpr.
void RWDBSimpleCaseExpr::else_ | ( | const RWDBExpr & | elseExpr | ) |
Specifies the ELSE
expression for self as elseExpr. If self already has an ELSE
clause, this method replaces it.
RWDBSimpleCaseExpr & RWDBSimpleCaseExpr::operator= | ( | const RWDBSimpleCaseExpr & | simpleCaseExpr | ) |
Assignment operator. Self shares an implementation with simpleCaseExpr. Returns a reference to self.
