> The query is expected to fail (because the table name in t.* does not match any of the
joined tables), but not with a NullPointerException. A similar query with ON instead of USING
fails more gracefully:
> ij> select t.* from t t1 join t t2 on t1.a=t2.a;
> ERROR 42X10: 'T' is not an exposed table name in the scope in which it appears.
