Method Detail
-
bindExpression
ValueNode bindExpression(FromList fromList, SubqueryList subqueryList, java.util.List<AggregateNode> aggregates) throws StandardException
Bind this logical operator. All that has to be done for binding a logical operator is to bind the operand, check that the operand is SQLBoolean, and set the result type to SQLBoolean.- Overrides:
bindExpression
in classUnaryOperatorNode
- Parameters:
fromList
- The query's FROM listsubqueryList
- 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
-
setFullTypeInfo
protected void setFullTypeInfo() throws StandardException
Set all of the type info (nullability and DataTypeServices) for this node. Extracts out tasks that must be done by both bind() and post-bind() AndNode generation.- Throws:
StandardException
- Thrown on error
