OpenJPA generates and executes SQL update for unchanged entities within
transaction.
Example:
factory = Persistence.createEntityManagerFactory("....",System.getProperties())
;
em = factory.createEntityManager() ;
em.getTransaction().begin() ;
Query q = em.createQuery("SELECT ......... ");
List l = q.getResultList() ;
System.out.println(l.size()) ;
em.getTransaction().commit() ;
em.close() ;
factory.close() ;
