{noformat}
SELECT deptno, name FROM emp JOIN dept USING (deptno) ORDER BY deptno{noformat}
is ok.
{code:java}
SELECT name FROM emp JOIN dept USING (deptno) ORDER BY deptno {code}
fails because `deptno` can not be found in OrderScope, it is only expanded into
a `COALESCE() AS` expression when explicitly querying the deptno field
was (Author: JIRAUSER300637):
{noformat}
SELECT deptno, name FROM emp JOIN dept USING (deptno) ORDER BY deptno{noformat}
> Unqualified common column in ORDER BY fails for JOINs with USING and for
> NATURAL JOINs
