Hello.
When I need to fetch multi-level relations of an entity I always do it
this way:
Query q = entityManager.createQuery("SELECT o FROM Gddist o WHERE
o.dist1cod IN (SELECT a.dist2cod.dist1cod FROM Gdalba a WHERE a.gdalbaPK =
:qGdalbaPK)");
ReadAllQuery query = (ReadAllQuery)((JpaQuery)q).getDatabaseQuery();
Expression ex = query.getExpressionBuilder();
query.addJoinedAttribute(ex.getAllowingNull("gdpobl"));
query.addJoinedAttribute(ex.getAllowingNull("gdpobl").getAllowingNull( "gdprov"));
q.setParameter("qGdalbaPK", gdalbaPK);
It always works well. But in this case I get an exception.
What am I doing wrong?
Thanks for your help:
Yolanda
