-
Method Details
-
bindExpression
ValueNode bindExpression(FromList fromList, SubqueryList subqueryList, List<AggregateNode> aggregates) throws StandardException Bind this expression. This means binding the sub-expressions, as well as figuring out what the return type is for this expression.- Overrides:
bindExpression
in classBinaryOperatorNode
- Parameters:
fromList
- The FROM list for the query this expression is in, for binding columns.subqueryList
- The subquery list being built as we find SubqueryNodesaggregates
- The aggregate list being built as we find AggregateNodes- Returns:
- The new top of the expression tree.
- Throws:
StandardException
- Thrown on error
-
generateExpression
Do code generation for this binary operator.- Overrides:
generateExpression
in classBinaryOperatorNode
- Parameters:
acb
- The ExpressionClassBuilder for the class we're generatingmb
- The method the code to place the code- Throws:
StandardException
- Thrown on error
