안녕하세요.

이번에도 쿼리 좀 도와 주세요.

PIVOT 사용하면 될거 같은데 잘안되요..ㅠ

여기서 항상 많은 도움 받고 있는데 쿼리가 제일 어려운거 같아요..ㅠ

초기값

SELECT 'T' FLAG, '100' AS CD, 'A' AS CD2, 400 AS VAL1, 200 VAL2 FROM DUAL UNION ALL

SELECT 'T' FLAG, '100' AS CD, 'B' AS CD2, 400 AS VAL1, 200 VAL2 FROM DUAL UNION ALL

SELECT 'T' FLAG, '100' AS CD, 'C' AS CD2, 400 AS VAL1, 200 VAL2 FROM DUAL UNION ALL

SELECT 'T' FLAG, '200' AS CD, 'A' AS CD2, 500 AS VAL1, 200 VAL2 FROM DUAL UNION ALL

SELECT 'T' FLAG, '200' AS CD, 'B' AS CD2, 500 AS VAL1, 200 VAL2 FROM DUAL UNION ALL

SELECT 'T' FLAG, '200' AS CD, 'C' AS CD2, 500 AS VAL1, 200 VAL2 FROM DUAL UNION ALL

SELECT 'T' FLAG, '300' AS CD, 'A' AS CD2, 660 AS VAL1, 300 VAL2 FROM DUAL UNION ALL

SELECT 'T' FLAG, '300' AS CD, 'B' AS CD2, 660 AS VAL1, 300 VAL2 FROM DUAL UNION ALL

SELECT 'T' FLAG, '300' AS CD, 'C' AS CD2, 660 AS VAL1, 300 VAL2 FROM DUAL UNION ALL

SELECT 'F' FLAG, '100' AS CD, 'A' AS CD2, 400 AS VAL1, 200 VAL2 FROM DUAL UNION ALL

SELECT 'F' FLAG, '100' AS CD, 'B' AS CD2, 400 AS VAL1, 200 VAL2 FROM DUAL UNION ALL

SELECT 'F' FLAG, '100' AS CD, 'C' AS CD2, 400 AS VAL1, 200 VAL2 FROM DUAL UNION ALL

SELECT 'F' FLAG, '200' AS CD, 'A' AS CD2, 500 AS VAL1, 200 VAL2 FROM DUAL UNION ALL

SELECT 'F' FLAG, '200' AS CD, 'B' AS CD2, 500 AS VAL1, 200 VAL2 FROM DUAL UNION ALL

SELECT 'F' FLAG, '200' AS CD, 'C' AS CD2, 500 AS VAL1, 200 VAL2 FROM DUAL UNION ALL

SELECT 'F' FLAG, '300' AS CD, 'A' AS CD2, 660 AS VAL1, 300 VAL2 FROM DUAL UNION ALL

SELECT 'F' FLAG, '300' AS CD, 'B' AS CD2, 660 AS VAL1, 300 VAL2 FROM DUAL UNION ALL

SELECT 'F' FLAG, '300' AS CD, 'C' AS CD2, 660 AS VAL1, 300 VAL2 FROM DUAL

결과값

CD	FLAG1	DIV	A	B	C	FLAG1	DIV	A	B	C
100	T	VAL1	400	400	400	F	VAL1	400	400	400
200	T	VAL1	500	500	500	F	VAL1	500	500	500
300	T	VAL1	660	660	660	F	VAL1	660	660	660
100	T	VAL2	200	200	300	F	VAL2	200	200	300
200	T	VAL2	200	200	300	F	VAL2	200	200	300
300	T	VAL2	300	300	300	F	VAL2	300	300	300

WITH t AS

UNION ALL SELECT 'F', '300', 'B', 660, 300 FROM dual

UNION ALL SELECT 'F', '300', 'C', 660, 300 FROM dual

)

SELECT *

  FROM t

 UNPIVOT (v FOR div IN (val1, val2))

 PIVOT (MIN(v) FOR cd2 IN ('A' a, 'B' b, 'C' c))

 PIVOT (MIN(a) a, MIN(b) b, MIN(c) c FOR flag IN ('T' t, 'F' f))

 ORDER BY div, cd

;



-- div  는 기준값이라 굳이 두번 표시할 필요가 없고 -> 한번만 표시

-- flag 는 구분값이라 굳이 두번 표시할 필요가 없고 -> 컬럼명에 표시
