JPQL for select from select row_number() over()

Question

I\'m using Db2 on AS/400, and I am trying to execute a JPQL query that will return results from row x to row y.

In SQL this works:

select cur.* from          


        

Answer 1

That cannot be done. JPQL operates to entities and entities are mapped to tables in database. Row number in db2 is concept in result set, not in database table.

Answer 2

Query q = em.createQuery("select e from SomeEntity e")
            .setFirstResult(0)
            .setMaxResults(10);
