안녕하세요!

DB공부중인 학생인데요~ 궁금한게 있습니다.

select문을 사용하여 조회를 하였는데요

1번과 2번 칼럼은 AA테이블이고 여기에 3번칼럼값을 가지고 있는 BB테이블을 조인시켜주었습니다.

AA테이블의 1,2번 칼럼은 값이 같은데 BB테이블의 3번칼럼값이 달라 아래로 펼쳐집니다.

       1          2         3

(주)가      도매      2013

(주)가      도매      2014

(주)나      제조      2014

이렇게 나오는 것을

 

        1         2         3         4

(주)가       도매    2013    2014

(주)나       제조   2014

 

이런식으로 바꾸고 싶습니다.

조언 좀 부탁드립니다~!!

AA 에는 1,2 컬럼이 있고

BB 에는 어떤 컬럼이 있는건지요?

AA 테이블과 BB 테이블을 Join 할때

어떤 조건으로 조인을 하셨는지?

대략적인 테이블 레이아웃이나

정보가 있어야 다른 분들도 댓글달기 수월할거 같아요.

서울에서 김서방 찾는거 같다는 느낌이 들어요..

글만보고서는..;;

 아~

AA테이블은 1,2 즉 회사와, 업종 컬럼이 있구요

BB테이블에는 3의컬

럼 즉 회사 거래날짜가 들어있습니다.

테이블 조인시에는 AA테이블에 left join을 하여 BB테이블을 걸어주었구요

 

select AA.1 , AA.2 , BB.3

from AA as AA

left join BB as BB

이렇게 걸어주었습니다.

실행시켜보니 위에 

  1          2         3

(주)가      도매      2013

(주)가      도매      2014

(주)나     제조       2014

이런식으로 출력이 되고있습니다.

제가 출력 하고 싶은것은

    1         2         3         3

(주)가       도매    2013    2014

(주)나       제조    2014

이런식으로  출력이 되게 하고싶습니다.

즉, AA테이블의 1,2컬럼의 값이 같고 BB테이블의 3컬럼의 값이 다르다면

같은 1,2컬럼의 값은 하나만 출력되고 그 옆으로 3컬럼의 값이 출력되게 하고싶습니다!

 아 join 할 때 조건은 BB테이블에 적어놓진 않았는데 1컬럼과 같은 값을 가지고 있는 컬럼으로 조인시켜주었습니다.

left join BB on AA.1 = BB.1

헉..댓글달고 우욱님꺼 보니..

SQL 공부 많이 해야겠다는 생각이 드네요 ㅜ.ㅜ

저렇게 짧은 구문을..

이렇게 길게 늘어뜨리는 것도

재능이겠죠?

-_-;;;
