아래형식으로 공백을 제거하여 위쪽으로 몰아서 출력시키고 싶은데 당최 감이오질않습니다..

어떻게 해야 위로 몰수있을까요..

아래 표에 보시면

COL01 번별로 하나의 값이 존재함으로 해당 값을 MAX로 하면 결과값만 올라옵니다.. 

 

  MAX(TO_CHAR(ADD_MONTHS(TO_DATE('201801','YYYYMM'),-12), 'YYYYMM') ) AS mm01,

  MAX(TO_CHAR(ADD_MONTHS(TO_DATE('201801','YYYYMM'),-11), 'YYYYMM')) AS mm02,

 

MAX(DECODE(SUBSTR(COL02,1,6), TO_CHAR(ADD_MONTHS(TO_DATE('201801','YYYYMM'),-12), 'YYYYMM'), count(*))) AS val01,

MAX(DECODE(SUBSTR(COL02,1,6), TO_CHAR(ADD_MONTHS(TO_DATE('201801','YYYYMM'),-11), 'YYYYMM'), count(*))) AS val02,

...

 

GROUP BY 

CASE

        WHEN COL01 IN ('01001', '01003') THEN '2번'

        WHEN COL01 IN ('02001') THEN '1번'

        WHEN COL01 IN ('02002', '02003') THEN '3번'

        ELSE '4번'

    END

○ 그룹바이에 연월이 들어 있어서 그래요.
  1. 그룹바이에서 연월을 빼시고
  2. DECODE(COUNT()) 를 COUNT(DECODE()) 로 바꾸셔야 합니다.
○ 쿼리에 비효율이 있네요.
  1. 조건절에서 컬럼가공하지 마세요.
    - 변경전 : SUBSTR(col02, 1, 6) <= '201801'
    - 변경후 : col02 <= '201801' || '31'
○ 쿼리를 간결하게
  1. 인라인뷰 활용 : 반복 구문 간결하게
  2. Months_Between 활용
