-------------------------------------
[~julianhyde] After my test, I still belive this HAVING form is *having
grouping_id(deptno,job,sal) !=0* . Not *7*
{code:java}
select deptno, job, sal, grouping(deptno), grouping(job), grouping(sal)
from testschema.emp
group by grouping sets (deptno, job, (deptno, job), (deptno, job, sal))
having grouping_id(deptno, job, sal) != 0;
{code}
some return value:

> When group key is a superset of the union of the groupKeys will generate the
