fetch join과 join

안녕하세요, 김영한님! @Query 안에 JPQL을 명시해주며 페이징/정렬 파트를 공부하고 있습니다.

해당 강의 21:42 쯤 강사님과 다르게 fetch join을 사용하였는데요, 이때 다음과 같은 예외가 발생하였습니다.

사용된 JPQL은 다음과 같습니다.

    @Query("select m from Member m left join fetch m.team where m.username = :username")
    Page<Member> findMembersWithTeamByUsername(@Param("username") String username, Pageable pageable);

 

여기서 countQuery를 구현하였더니 정상적으로 작동하였습니다.

    @Query(value = "select m from Member m join fetch m.team where m.username = :username", countQuery = "select count(m) from Member m")
    Page<Member> findMembersWithTeamByUsername(@Param("username") String username, Pageable pageable);

질문1) @Query() 안에 join fetch를 넣으면 countQuery를 반드시 정의 해주어야하나요?

 

질문2) 위와 같은 예외가 왜 발생했는지 궁금합니다.

감사합니다!
