Benoemde Query in slaapstand zetten - voeg samen met 3 tabellen

@NamedQuery

Ik heb de volgende @NamedQuery gemaakt op de Organization entiteitsklasse.

@NamedQuery(name = "query", query = "SELECT DISTINCT o " +
    "FROM Organization o, User u " +
    "JOIN o.roles oRole " +
    "JOIN u.roles uRole " +
    "WHERE oRole.id = uRole.id AND u.id = :uId")
public class Organization { ...

_{(Ik gebruikte standaard JPA-annotaties, maar mijn provider was Hibernate.)}

Test

Dit is de test die ik heb gedaan.

EntityManager em = ...
TypedQuery<Organization> q = em.createNamedQuery("query", Organization.class);
q.setParameter("uId", 1); // try it with 1L if Hibernate barks about it
for (Organization o : q.getResultList())
  System.out.println(o.name);

Met behulp van de tabellen en voorbeeldgegevens hieronder, levert dit

A
B

Kijk of het voor u werkt.
