这个 JPQL 有什么问题：'No data type for node'

Question

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

Caused by: java.lang.IllegalStateException: No data type for node: org.hibernate.hql.internal.ast.tree.IdentNode

我无法发现问题

Answer 1

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

Answer 2

programmeId 不是您 "select" 中定义的别名。
