JPQL查询-节点的内部联接无数据类型

Question

I have the following JPQL query which is used to select all programmes featuring a performer with a specified id.

The ChannelProgramme entity has a programme and an episode

There is also an entity called ProgEpPerfAssociation, featuring the programmeId, performerId and episodeId. (A performer can feature in many programmes and episodes and a programme/episode can feature many performers)

@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")

However I am getting the following exception

Caused by: java.lang.IllegalArgumentException: Validation failed for query for method public abstract java.util.List com.tvfreakz.repository.ChannelProgrammeRepository.findScheduledPerformerProgrammes(java.lang.Long,java.util.Date,java.util.Date)!

I'm not sure what's wrong with the JPQL

Answer 1

Thanks to the commenters, it pointed me in the right direction. I didn't need to do a join at all in the end

@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")
