【问题描述】：

我有以下查询

  @Query("Select cp from ChannelProgramme cp"
      + " where cp.programme.programmeId in (select programmeId from Programme programme"
      + " inner join programme.performers performer"
      + " where performer.performerId in :performerID)"
      + " AND (cp.progDate BETWEEN :fromDate AND :toDate)"
      + " ORDER BY cp.progDate, cp.startTime")
  List<ChannelProgramme> findScheduledPerformerProgrammes(@Param("performerID") Long performerId, @Param("fromDate") Date fromDate, @Param("toDate") Date toDate);

抛出以下异常

我找不到问题

标签： java hibernate jpql

【解决方案1】：

这个select programmeId from Programme programme 必须是select Programme.programmeId from Programme Programme

【讨论】：

谢谢！我一直盯着那个，直到我脸色发青！

【解决方案2】：

programmeId 不是您的“选择”中定义的别名。
