I have simple JPA query as following. I run actual SQL (logged in trace log), it does return rows, but with JPA /Hibernate it does not !

Code:

            
            q = em.createQuery("SELECT o FROM Tuser AS o WHERE o.in :tuserList AND  SUBSTRING(o.createdOn,1,11)  = '09-NOV-2012'", Tuser.class);
            q.setParameter("tuserList", tuserList);
            List list = q.getResultList();

If I remove SUBSTRING clause, it returns. But with SUBSTRING clause underlying query does return result in SQLDeveloper.

Hi,

I suggest you to use p6spy (or any other jdbc-profiler) in order to detect into which sql-statement exactly hibernate transforms your original query. I guess this will uncover the problem.
