Namit Jain commented on HIVE-581:
---------------------------------
Cant argue against making it configurable ?
In mysql, group by 1 means grouping by the first position.
But, keeping it configurable leaves all the interpretations open, and we can
use the same config. variable for order by also
> improve group by syntax

> It would be nice if group by allowed either column aliases or column position
> (like mysql).
> It can be burdensome to have to repeat UDFs both in the select and in the
> group by.
> e.g. instead of:
> select f1(col1), f2(col2), f3(col3), count(1) group by f1(col1), f2(col2),
> f3(col3);
> it would allow:
> select f1(col1), f2(col2), f3(col3), count(1) group by 1, 2, 3;
