왼쪽 테이블에 100 개의 레코드가 있지만 9 개의 레코드 만 표시합니다 !! –

에 의해 요약 및 그룹화 중입니다. 기록이 적은 것은 정상입니다. –

@GiannisParaskevopoulos가 합계와 그룹으로이 열을 모두 가지고있는 솔루션을 알려주십시오. –

확인 아래 2 가지 방법 중 하나를 사용하지만 두 번째 것을 선호합니다 1) 서브 쿼리 을 사용하십시오 2) 먼저 별도의 쿼리에서 집계를 수행하고 왼쪽 테이블과 다시 결합하십시오 ... 쿼리가 비슷한 것이어야합니다 코드 아래 :

왼쪽 + 위 열의 모든 레코드를 갖기 위해 어떻게해야합니까 ??? –

편집 된 코드를 확인하십시오 ... –

은 매력처럼 작동하지만 알려주십시오. 귀하의 코드가 성능면에서 나 그보다 나은 이유는 무엇입니까? –

left join은 모든 레코드를 표시하지 않습니다.
