Reynold Xin updated SPARK-12789:
--------------------------------
Description:
This is to support order by position in SQL, e.g.
{noformat}
select c1, c2, c3 from tbl order by 1, 3
{noformat}
should be equivalent to
{noformat}
select c1, c2, c3 from tbl order by c1, c3
{noformat}
was: Num in Order by is treated as constant expression at the moment. I guess
it would be good to enable user to specify column by index which has been
supported in Hive 0.11.0 and later.
