Spring-Data FETCH JOIN with Paging is not working

Question

I am trying to use HQL fetching my entity along with sub-entities using JOIN FETCH, this is working fine if I want all the results but it is not the case if I want a Page

Answer 1

You have to specify countQuery param for @Query and now you can use Page or List as return value.

@Query(value = "SELECT v FROM VisitEntity v LEFT JOIN FETCH v.comments WHERE v.venue.id = :venueId and ...",
       countQuery = "SELECT count(v) FROM VisitEntity v LEFT JOIN v.comments WHERE v.venue.id = :venueId and ..." )
public Page getVenueVisits(@Param("venueId") long venueId,...,
        Pageable pageable);
