Вот запрос Hibernate, где я получаю исключение: - ** Примечание: - ** Тот же запрос работает хорошо, когда я использую My SQL 5.1 с теми же данными.Еще одна вещь, когда я использую My SQL 5.7.23 RDS соединение, все приложение работает медленно.Новая RDS имеет в 4 раза более высокую конфигурацию от службы 5.1 My SQL RDS, но все равно выдает ошибку.
Вот запрос: -
Session session = em.unwrap(Session.class);
Criteria criteria = session.createCriteria(Orgassociation.class, "orgassociation");
criteria.createAlias("orgassociation.organization", "associatedOrgs");
Criteria userCriteria = session.createCriteria(User.class, "user");
userCriteria.add(Restrictions.eq("user.userId", userId));
User user = (User) userCriteria.uniqueResult();
criteria.add(Restrictions.eq("orgassociation.organization1.organizationId",
user.getOrganization().getOrganizationId()));
criteria.add(Restrictions.eq("associatedOrgs.orgType", VMS_CONSTANTS.DB_CONSTANTS.EMPLOYER_AND_SUPPLIER));
criteria.addOrder(Order.desc("orgassociation.orgAssociationId"));
criteria.setMaxResults(5);
@SuppressWarnings("unchecked")
List<Orgassociation> orgList = criteria.list();
