jak rozdělit sloupce ve výsledku dotazu v databázi Oracle

Použijte PIVOT a ROW_NUMBER analytická funkce:

SQL Fiddle

Nastavení schématu 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;

Dotaz 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 )
)

Výsledky :

|   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) |

Pokud chcete první a druhý řádek na stejném řádku, stačí změnit CAT před vygenerováním ROW_NUMBER a PIVOT ing.
