@Query不会返回任何结果

Question

我在我的存储库类中使用Spring Data JPA的@Query注释。当我在PL-SQL开发人员中运行相同的sql时，它返回结果但不在应用程序内部。问题是什么 ？我该怎么办呢？请帮助。 提前致谢

我的回购课程：

@Repository
public interface FiberChannelRepository extends FndJpaRepositiry<FiberChannel, Long> {

  @Query("select n.id, c.id, loc from FiberChannel fc  left join Channel c on fc.id=c.id left join ChannelNode cn on c.id = cn.id and cn.deleted != true  left join Node n  on cn.id = n.id and cn.deleted != true  left join Location loc on loc.id = n.id and cn.deleted != true where fc.id=?1")
  List<Object[]> findNodesByFiber_Id(Long idFiber);

}

SQL变体：

select n.id_node, c.id_channel, loc.*
  from Fiber_Channel fc 
      left join channel c on fc.id_channel=c.id_channel  
  left join CHANNEL_NODE cn
      on c.id_channel = cn.id_channel and cn.is_deleted != 1 
  left join Node n 
      on cn.id_node = n.id_node and cn.is_deleted != 1 
  left join Location loc
      on loc.id_location = n.id_location and cn.is_deleted != 1 where 
fc.id_fiber=42266

我已经解决了我的问题。我在查询sql中犯了错误。我用fc.fiber.id替换fc.id，现在可以正常工作。
