Subject [jira] Created: (OPENJPA-25) Incorrect SQL generated for queries involving more than one AbstractSchemaNames, generated SQL FROM clause is missing 'Table alias'
Date Mon, 21 Aug 2006 18:14:15 GMT
Incorrect SQL generated for queries involving more than one AbstractSchemaNames, generated
SQL FROM clause is missing 'Table alias'
-----------------------------------------------------------------------------------------------------------------------------------

                 Key: OPENJPA-25
                 URL: http://issues.apache.org/jira/browse/OPENJPA-25
             Project: OpenJPA
          Issue Type: Bug
          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)
