Utiliser un PIVOT
et le ROW_NUMBER
fonction analytique :
Configuration du schéma Oracle 11g R2 :
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;
Requête 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 )
)
| 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) |
Si vous voulez que les première et deuxième lignes soient sur la même ligne, changez simplement le CAT
la colonne doit être en minuscules avant de générer le ROW_NUMBER
