카카오톡 처럼 채팅방 만들려고 하는데
관련링크
본문
위 사진 2번째 화면에 채팅방 입장 버튼있는곳이 카톡처럼 최신 대화내용 한줄 나오고 최신 대화순서대로 정렬되는 것인데 이거 mysql 뽑기가 어렵네요.
혹시 조언 주시면 감사하겠습니다.
답변시 도움이 될 것 같아 아직 미완성인 저의 mysql 코드 공개합니다.

답변 2
memo 테이블을 기준으로
group by 채팅방
order by wr_datetime desc
이렇게 하면 마지막 대화 1개씩 가져오지 않을까요?
리스트 가져오실때
order by 채팅시간컬럼 desc
이렇게 한번 더 뿌려주면 되지 않나요?
