Subject [jira] Created: (OPENJPA-83) Bad SQL for Subselect BETWEEN
Date Wed, 15 Nov 2006 19:51:37 GMT
Bad SQL for Subselect BETWEEN
-----------------------------

                 Key: OPENJPA-83
                 URL: http://issues.apache.org/jira/browse/OPENJPA-83
             Project: OpenJPA
          Issue Type: Bug
          Components: query
         Environment: openJPA 0.9.7
MySQL 5.0.15
            Reporter: Jakob Braeuchi


the following query generates an sql with no table in the FROM-clause of the subselct:

em.createQuery("select k from Kauf k where " +
"((select sum(p.betrag) from Posten p where p.kauf = k) between :betrVon and :betrBis) " +
"order by k.datum asc");

SELECT t1.id, t1.bemerkung, t1.datum, t2.id, t2.idEinkauferAlt, t2.name
FROM ekv2kauf t1 LEFT OUTER JOIN ekv2einkaufer t2 ON t1.idEinkaufer = t2.id
WHERE ((SELECT SUM(t0.betrag) FROM WHERE (t0.idKauf = t1.id)) >= ? AND (SELECT SUM(t0.betrag)
FROM WHERE (t0.idKauf = t1.id)) <= ?) ORDER BY t1.datum ASC
[params=(double) 1800.0, (double) 3000.0]

when i use the query without BETWEEN it works:

em.createQuery("select k from Kauf k where " +
"((select sum(p.betrag) from Posten p where p.kauf = k) > :betr) " +
"order by k.datum asc");

SELECT t1.id, t1.bemerkung, t1.datum, t2.id, t2.idEinkauferAlt, t2.name
FROM ekv2kauf t1 LEFT OUTER JOIN ekv2einkaufer t2 ON t1.idEinkaufer = t2.id
WHERE ((SELECT SUM(t0.betrag) FROM ekv2posten t0 WHERE (t0.idKauf = t1.id)) > ?)
ORDER BY t1.datum ASC
[params=(double) 1800.0]

when i rewrite the query using groupby / having it also works, but the generated sql does
not use BETWEEN:

em.createQuery("select p.kauf from Posten p " +
        "group by p.kauf " +
                "having sum(p.betrag) between :betrVon and :betrBis " +
                "order by p.kauf.datum asc");

SELECT t1.id, t1.bemerkung, t1.datum, t1.idEinkaufer
FROM ekv2posten t0 INNER JOIN ekv2kauf t1 ON t0.idKauf = t1.id
GROUP BY t1.id, t1.bemerkung, t1.datum, t1.idEinkaufer
HAVING SUM(t0.betrag) >= ? AND SUM(t0.betrag) <= ?
ORDER BY t1.datum ASC
[params=(double) 1800.0, (double) 3000.0]
