> Implement multiargument GROUPING function
> -----------------------------------------
>
> Key: HIVE-15996
> URL: https://issues.apache.org/jira/browse/HIVE-15996
> Project: Hive
> Issue Type: New Feature
> Affects Versions: 2.2.0
> Reporter: Carter Shanklin
> Assignee: Jesus Camacho Rodriguez
> Attachments: HIVE-15996.01.patch
>
>
> Per the SQL standard section 6.9:
> GROUPING ( CR1, ..., CRN-1, CRN )
> is equivalent to:
> CAST ( ( 2 * GROUPING ( CR1, ..., CRN-1 ) + GROUPING ( CRN ) ) AS IDT )
> So for example:
> select c1, c2, c3, grouping(c1, c2, c3) from e011_02 group by rollup(c1, c2,
> c3);
> Should be allowed and equivalent to:
> select c1, c2, c3, 4*grouping(c1) + 2*grouping(c2) + grouping(c3) from
> e011_02 group by rollup(c1, c2, c3);
