Hibernateのクエリは、QueryException例外

Question

iは、クエリがあります。

final Query query2 = session.createQuery("FROM CallDetailHistoriesEntity WHERE unique_id = :id OR unique_id IN (SELECT linked_id FROM CallDetailHistoriesEntity WHERE unique_id = :id)"); 

をしかし、私は例外を持っています。どうして？

Answer 1

エンティティにはlinked_idという名前のプロパティはありません。しかし、linkedIdという名前のものがあります。したがって、JPQLクエリで使用する必要があります。

また、Javaの命名規則に従うことを強くお勧めします。変数とメソッドにはJavaではアンダースコアが使用されず、camelCaseが使用されます。だから私はunique_idをuniqueId,source_caller_idからsourceCallerIdなどに改名しました。もちろん、ゲッターとクエリはそれに応じて変更する必要があります。

次のステップは、JPA/Hibernateの全体のポイントが、関連付けを使用して相互接続されたエンティティのグラフを持つことであることに気づくことです。したがって、ほとんどの場合、エンティティに文字列型のlinkedId属性はなく、別のエンティティへのManyToOneまたはOneToOneの関連付けを持つ必要があります。これは、コード内のエンティティのグラフに移動し、クエリで結合を使用することです。
