하나의 레코드를 여러개로 만드는 방법 1 5 3,737

by 박준 [SQL Query] 열을행으로 UNPIVOT [2012.03.13 16:18:28]


안녕하세요.
다름이 아니라 결과가 하나로 나오는 쿼리를 여러개의 쿼리로 바꾸고 싶습니다.

조언 좀 부탁드리겠습니다.

9i 입니다.

select YYMM, GOODS, BASE_GUBUN, BASE_AMT, USE_GUBUN, USE_AMT, UTIL_GUBUN, AMT_UTIL
from a_table


YYMM GOODS BASE_GUBUN BASE_AMT USE_GUBUN USE_AMT UTIL_GUBUN AMT_UTIL
201103 D07 기본료 9240 장비임대료 4400 부가서비스 0
201103 D44 기본료 0 장비임대료 0 부가서비스 1320
201103 406 기본료 14570 장비임대료 0 부가서비스 0
201104 D07 기본료 9240 장비임대료 4400 부가서비스 0

위의 내용을

YYMM GOODS GUBUN AMT
201103 D07 기본료 9240
201103 D44 기본료 0
201103 406 기본료 14570
201104 D07 기본료 9240
201103 D07 장비임대료 4400
201103 D44 장비임대료 0
201103 406 장비임대료 0
201104 D07 장비임대료 4400
201103 D07 부가서비스 0
201103 D44 부가서비스 1320
201103 406 부가서비스 0
201104 D07 부가서비스 0


이렇게 변경하는 쿼리를 아무리 찾아봐도 비슷한것이 없네요.

부탁드리겠습니다.

감사합니다.

11g라면 Pivot 기능을 사용해 보세요.

애석하게도.. 9i  입니다.
