인프런 커뮤니티 질문&답변

안녕하세요 정말 좋은강의 잘듣고 있습니다.

혹시 countquery옵션을 설정했음에도 안나가는 경우가 있을까요?

이전 jpa 활용2 에서 order 객체를 기반으로 springdata jpa repository 를 만든후 아래와 같은 메서들를 정의했는데

@Query(value = "select o from Order o join fetch o.member m join fetch o.delivery d",countQuery = "select count(o) from Order o")
public Page<Order> findAllWithMemberDelivery(Pageable pageable);

결과값은 count 문없이 아래와 같은 쿼리만 나가네요 

 select

        order0_.order_id as order_id1_6_0_,

        member1_.member_id as member_i1_4_1_,

        delivery2_.delivery_id as delivery1_2_2_,

        order0_.delivery_id as delivery4_6_0_,

        order0_.member_id as member_i5_6_0_,

        order0_.order_date as order_da2_6_0_,

        order0_.status as status3_6_0_,

        member1_.city as city2_4_1_,

        member1_.street as street3_4_1_,

        member1_.zipcode as zipcode4_4_1_,

        member1_.name as name5_4_1_,

        delivery2_.city as city2_2_2_,

        delivery2_.street as street3_2_2_,

        delivery2_.zipcode as zipcode4_2_2_,

        delivery2_.status as status5_2_2_ 

    from

        orders order0_ 

    inner join

        member member1_ 

            on order0_.member_id=member1_.member_id 

    inner join

        delivery delivery2_ 

            on order0_.delivery_id=delivery2_.delivery_id limit ?

혹시 inner join 이라 따로 다시 조회할 이유가 없어서 스프링에서 최적화해서 따로 쿼리가 나가지 않은건가요?
