Examples of org.hibernate.Query.iterate()

org.hibernate.Query.iterate()
Return the query results as an Iterator. If the query contains multiple results pre row, the results are returned in an instance of Object[].

Entities returned as results are initialized on demand. The first SQL query returns identifiers only.
@return the result iterator @throws HibernateException

            for (Object o : metadata.values()) {
                EntityPersister persister = (EntityPersister) o;
                String className = persister.getEntityName();
                log.debug("Trying select * from: " + className);
                Query q = session.createQuery("from " + className + " c");
                q.iterate();
                log.debug("ok: " + className);
            }
        } finally {
            session.close();
        }
