> create table e011_01 (c1 int, c2 smallint);
> insert into e011_01 values (1, 1), (2, 2);
> {code}
> These queries should work:
> {code:sql}
> select distinct c1, count(*) from e011_01 group by c1;
> select distinct c1, avg(c2) from e011_01 group by c1;
> {code}
> Currently, you get :
> FAILED: SemanticException 1:52 SELECT DISTINCT and GROUP BY can not be in the
> same query. Error encountered near token 'c1'
