Review Comment:
I tried to add such case locally in my branch, and it works just fine on
`SqlToRelConverterTest`, but it fails with `Caused by:
java.lang.NullPointerException: cm.mapCorToCorRel.get($cor0)` in `QuidemTest`.
I tried to add following test case:
```
select
(select ename || ' from dept '
|| (select dname from dept where deptno = emp.deptno and
emp.empno = empnos.empno)
from emp
) as ename_from_dept
from (values (7369), (7499)) as empnos(empno) order by 1;
```
