JPA更新查詢問題

Question

假設我們有2個實體

@Entity(name = "user")
@Inheritance(strategy = InheritanceType.JOINED)
public class User{

 @Id
 @GeneratedValue(strategy = GenerationType.AUTO)
 private Long id;

 private String name;
}

另一個繼承的類

@Entity
public class ExtendedUser extends User{
   private String bio;
}

現在，當我嘗試運行JPA Update查詢時

@Modifying
@Query("update ExtendedUser  set bio=?2 where id=?1")
void updateOverflowText(Long id,String bio);

我收到異常，由於列“ id”不明確，無法運行查詢

嘗試這個：

@Modifying 
@Query( nativeQuery = true, value = "update user set bio=?2 where id=?1")
int updateOverflowText( Long id, String bio );    `
