SQL - Tableau croisé dynamique et grouper par ne fonctionne pas

Vous ne pouvez pas GROUP BY activity, document, extraction dans le PIVOT opérateur de table, le PIVOT L'opérateur déduit automatiquement les colonnes groupées. Mais vous pouvez l'écrire ainsi :

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;

Cela vous donnera :

| PRODUCT | TOTALUSERS |                   LATESTDATE | DOCUMENT | EXTRACTION |
-------------------------------------------------------------------------------
|   prodA |         60 | March, 02 2013 02:00:00+0000 |      113 |        152 |
