             Summary: Add support for GROUPING function for rollup aggregation
                 Key: TRAFODION-2312
                 URL: https://issues.apache.org/jira/browse/TRAFODION-2312
             Project: Apache Trafodion
          Issue Type: New Feature
            Reporter: Anoop Sharma
            Assignee: Anoop Sharma
            Priority: Minor


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).
