> Components: query
> Reporter: Catalina Wei
>
> select e, d from EmpBean e, DeptBean d generates following SQL where t2 is
> undefined:
> SELECT t1.empid, t2.deptno FROM EmpBean t0 JOIN EmpBean t1 ON (1 =
> 1)
> 'DeptBean t2' is missing in the FROM clause.
> Similar problem occurs to the following query:
> select d from EmpBean e left join e.dept d, ProjectBean p where e.salary =
> p.budget ==> incorrect SQL (t3 is undefined):
> SELECT t1.deptno, t1.budget, t1.mgr_empid, t1.name, t1.reportsTo_deptno FROM
> EmpBean t0 LEFT OUTER JOIN DeptBean t1 ON t0.dept_deptno = t1.deptno JOIN
> EmpBean t2 ON (1 = 1) WHERE (t2.salary = t3.budget)
