SQL - Pivot table dan group dengan tidak bekerja

Anda tidak dapat GROUP BY activity, document, extraction dalam PIVOT operator tabel, PIVOT operator menyimpulkan kolom yang dikelompokkan secara otomatis. Tapi Anda bisa menulisnya seperti ini:

WITH Pivoted
AS
(
  SELECT *
  FROM table1
  PIVOT 
  ( 
    sum([Count]) FOR [Type] IN ( Document , 
                                Extraction)
  ) AS p
) 
SELECT 
  product,
  SUM(Users) AS TotalUsers,
  MAX(DAte) AS LatestDate,
  MAX(Document) AS Document,
  MAX(Extraction) AS Extraction
FROM Pivoted
GROUP BY Product;

Ini akan memberi Anda:

| PRODUCT | TOTALUSERS |                   LATESTDATE | DOCUMENT | EXTRACTION |
