Oracle10g SQL pivot

Saya lebih suka menggunakan solusi GROUP BY dengan ekspresi CASE.

SELECT 
    id,
    MAX(CASE WHEN emailRank = 1 THEN email END) AS [1],
    MAX(CASE WHEN emailRank = 2 THEN email END) AS [2],
    MAX(CASE WHEN emailRank = 3 THEN email END) AS [3],
    MAX(CASE WHEN emailRank = 4 THEN email END) AS [4]
FROM (
    SELECT
        id, 
        email, 
        ROW_NUMBER() OVER (PARTITION BY id ORDER BY email) AS emailRank
    FROM TABLE
)
GROUP BY id;

Contoh Pivot asli memiliki tipe dan ")" hilang. Coba yang berikut ini agar pivot berfungsi:

pivot( max(email) FOR emailRank IN (1,2,3));
