オブジェクトクエリ言語を使用してクエリから結果リストを取得する方法

Question

JPA/Hibernateを使用しています リストアを行うためにcreatequeryを使用する方法を知りたいのですが、

EntityManagerFactory emf=Persistence.createEntityManagerFactory("JiraMapPUKPI"); 
EntityManager em= emf.createEntityManager(); 
EntityTransaction entr=em.getTransaction(); 
entr.begin(); 
Query multipleSelect =em.createQuery("select distinct k.kpiName FROM Kpi k ,ProfilUser p ,AssociationKpiProfil a WHERE p.profilUserId= :w and p.profilUserId= a.profilUser and a.kpi=k.kpiId ").setParameter("w", userid); 

をしかし、私は使用しカント：： 私が試してみました

List userList = (List)multipleSelect.getResultList(); 

multipleSelectはgetResultList方法

を含んではいけないと私も試してみましたので：

javax.persistence.Query multipleSelect= em.createQuery("select k.kpiName FROM Kpi k ,ProfilUser p ,AssociationKpiProfil a WHERE p.profilUserId= :w and p.profilUserId= a.profilUser and a.kpi=k.kpiId "); 
    multipleSelect.setParameter("w", userid); 
    List usrpro= multipleSelect.getResultList(); 

しかし、これをエラーが表示されます：

どうすればいいですか？ ありがとうございました

Answer 1

Hibernateによって生成されたクエリが正しくありません。 t1.PROFIL_USER_IDパラメータは存在しません。あなたのマッピングをチェックし、等号の代わりにJOINを使ってみてください。
