> GROUP BY ROLLUP aggregation generates and returns a null value to
> represent a rollup group.
> See jira trafodion-2246 for ROLLUP details. 
> This current jira is an extension of it.
> GROUPING function is used to determine whether a returned null value
> is due to a rollup group.
> It returns '1' if a null value is a rollup null and '0' otherwise (for non-null
> or data null values).
