@Query(value = "SELECT p FROM Post p" +
            " JOIN FETCH p.board" +
            " JOIN  p.board.team" +
            " WHERE p.board.id = :boardId",
        countQuery = "SELECT count(p) FROM Post p WHERE p.board.id = :boardId")
    Page<Post> selectAllPostsByBoardId(@Param("boardId") Long boardId, Pageable pageable);
