반응형
SQL에서 기본적으로 세로로 출력되는 리스트를 가로 형태로 출력을 해야 할 경우
-- 1 --
SELECT AGE,SEX, COUNT(*) AS CNT
FROM TABLE_SAMPLE
WHERE TR_DT BETWEEN '20000101' AND '20201231'
GROUP BY AGE, SEX;
-- 2 --
SELECT AGE, DECODE(SEX, 'M', CNT) AS M_CNT, DECODE(SEX, 'F', CNT) AS F_CNT
FROM (
SELECT AGE, SEX, COUNT(*) AS CNT
FROM TABLE_SAMPLE
WHERE TR_DT BETWEEN '20000101' AND '20201231'
GROUP BY AGE, SEX
);
-- 3 --
SELECT AGE, MIN(DECODE(SEX, 'M', CNT)) AS M_CNT, MIN(DECODE(SEX, 'F', CNT)) AS F_CNT
FROM (
SELECT AGE, SEX, COUNT(*) AS CNT
FROM TABLE_SAMPLE
WHERE TR_DT BETWEEN '20000101' AND '20201231'
GROUP BY AGE, SEX
)GROUP BY AGE
ORDER BY AGE;
