> Query with GROUP BY and JOIN ... USING wrongly fails with "Column 'DEPTNO' is
> ambiguous" error. Here is the query:
> {code}
> select deptno, count(*)
> from emp
> join dept using (deptno)
> group by deptno;
> {code}
> Because of USING, the two deptno fields should be merged into one, and
> therefore {{deptno}} is not ambiguous. That query works in Oracle. Also note
> that
> {code}select deptno
> from emp
> join dept using (deptno)
> {code}
> works correctly in Calcite, and has since CALCITE-2227 was fixed.
