Question

我有以下JPQL查询，用于选择具有指定id的表演者的所有节目。

ChannelProgramme实体有一个节目和一集

还有一个名为ProgEpPerfAssociation的实体，其特色是programmeId，performerId和episodeId。（表演者可以在许多节目和剧集中出现，节目/剧集可以包含许多表演者）

@Query("Select cp from ChannelProgramme cp"
    + " where cp.programme.programmeId in (select programme from ProgEpPerfAssociation prog"
    + " inner join prog.performer perf"
    + " where prog.performerId in :performerID)"
    + " AND (cp.startTime BETWEEN :fromDate AND :toDate)"
    + " ORDER BY cp.startTime, cp.startTime")

但是我得到以下异常

我不确定JPQL的错误

Answer 1

感谢评论者，它指出了我正确的方向。我最后根本不需要加入

@Query("Select cp from ChannelProgramme cp"
    + " where cp.programme.programmeId in (select programmeId from ProgEpPerfAssociation"
    + " where performerId = :performerID)"
    + " AND (cp.startTime BETWEEN :fromDate AND :toDate)"
    + " ORDER BY cp.startTime, cp.startTime")

JPQL查询 - 内部连接没有节点的数据类型
