Subject [jira] Created: (OPENJPA-81) Wrong alias used when querying an attribute of a 1:n child
Date Mon, 13 Nov 2006 20:25:37 GMT
Wrong alias used when querying an attribute of a 1:n child
----------------------------------------------------------

                 Key: OPENJPA-81
                 URL: http://issues.apache.org/jira/browse/OPENJPA-81
             Project: OpenJPA
          Issue Type: Bug
          Components: query
         Environment: openJPA 0.9.7
MySQL 5.0.15
            Reporter: Jakob Braeuchi


the query over the 1:n relationship 'katergorien' 

em.createQuery("select distinct k from KategorieGruppe k " +
            		"where k.kategorien.bezeichnung like ?1 " +
            		"order by k.bezeichnung asc");

uses a wrong alias t2 in the generated SQL:

SELECT DISTINCT t0.id, t0.bezeichnung FROM ekv2kategoriegruppe t0 INNER JOIN ekv2kategorie
t1 ON t0.id = t1.idGruppe WHERE (t2.bezeichnung LIKE ? ESCAPE '\\') ORDER BY t0.bezeichnung
ASC [params=(String) F%]

Unknown column 't2.bezeichnung' in 'where clause'
