Använd en PIVOT
och ROW_NUMBER
analytisk funktion:
Oracle 11g R2 Schema Setup :
CREATE TABLE your_query_result (sal, cat, id, shop ) AS
SELECT 1900, '34R5', 10, 'dense' FROM DUAL UNION ALL
SELECT 1900, '34r5', 10, 'SVM' FROM DUAL UNION ALL
SELECT 1900, '34r5', 10, 'bpo' FROM DUAL UNION ALL
SELECT 2345, '3ER4', 11, 'kpo' FROM DUAL UNION ALL
SELECT 2345, '3ER4', 11, 'infra' FROM DUAL UNION ALL
SELECT 12345, '34F4', 12, 'const' FROM DUAL;
Fråga 1 :
SELECT sal,
cat,
id,
"1_SHOP" AS shop_1,
"2_SHOP" AS shop_2,
"3_SHOP" AS shop_3
FROM (
SELECT r.*,
ROW_NUMBER() OVER (
PARTITION BY sal, cat, id
ORDER BY shop
) AS rn
FROM (
SELECT * FROM your_query_result
) r
)
PIVOT (
MAX( shop ) AS shop
FOR rn IN ( 1, 2, 3 )
)
Resultat :
| SAL | CAT | ID | SHOP_1 | SHOP_2 | SHOP_3 |
|-------|------|----|--------|--------|--------|
| 1900 | 34R5 | 10 | dense | (null) | (null) |
| 1900 | 34r5 | 10 | SVM | bpo | (null) |
| 2345 | 3ER4 | 11 | infra | kpo | (null) |
| 12345 | 34F4 | 12 | const | (null) | (null) |
Om du vill ha den första och andra raden på samma rad, ändra bara CAT
kolumnen ska vara med gemener innan du genererar ROW_NUMBER
och PIVOT
