- 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 class UnaryOperatorNode
    
    Parameters:
    
    fromList - The query's FROM list
    
    subqueryList - The subquery list being built as we find SubqueryNodes
    
    aggregates - 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
