Menggabungkan beberapa baris menjadi satu baris dan menambahkan kolom tergantung pada jumlah baris

Anda dapat menggunakan opsi dengan dynamicSQL, TERAPKAN( ) dan PIVOT operator. Dalam skenario ini urutan kolom dalam hasil, diurutkan berdasarkan kolom Col4.

DECLARE @cols nvarchar(max),
        @query nvarchar(max)
SELECT @cols =

         FROM (
               SELECT ',' + QUOTENAME('Col' + CAST(3 + ROW_NUMBER() OVER(PARTITION BY Col1, Col2, Col3 ORDER BY Col4) AS nvarchar(10))) AS ColName,
                      ROW_NUMBER() OVER(PARTITION BY Col1, Col2, Col3 ORDER BY Col4) AS rn
               FROM dbo.test31 CROSS APPLY (VALUES('Col'), ('Col'), ('Col')) o(Col)) x
         GROUP BY x.ColName, x.rn
         ORDER BY x.rn                   
         FOR XML PATH(''), TYPE).value('.', 'nvarchar(max)'), 1, 1, '')
SET @query =

            COALESCE(CAST(o.oCol4 AS nvarchar(10)), o.oCol5, o.oCol6) AS ListValues

     PIVOT

       ) p'

Opsi dengan nama kolom seperti ini " Plant, Brand, Area1, DownTime1, Reasons1, Area2, DownTime2, Reasons2 dan seterusnya."
