Example 6 with Predicate

use of javax.persistence.criteria.Predicate in project hibernate-orm by hibernate.

    Predicate p1 = builder.equal(orderRoot.get("id"), "order-1");
    Predicate p2 = builder.equal(orderRoot.get("id"), "order-2");
    Predicate compoundPredicate = builder.and(p1, p2).not();
    // a negated AND should become an OR
    assertEquals(Predicate.BooleanOperator.OR, compoundPredicate.getOperator());
    orderCriteria.where(compoundPredicate);
    List<Order> orders = em.createQuery(orderCriteria).getResultList();
    assertEquals(3, orders.size());

    em.close();
}
