總和迴轉列

Question

我有這樣的GridView與擺動數據：

Store  MEX  USA 
    Supermarket 10,000 5,000 
    Club   10,000  0 
    Direct  4,000 1,000 

與此查詢完成：

SELECT * 
    FROM [Sales] 
    PIVOT ( 
      SUM(Sales) 
      FOR Region IN ([MEX], [USA]) 
    ) AS SalesPerRegion 

現在我想在頁腳添加在墨西哥的銷售總額和美國，我不知道該怎麼做。

任何幫助表示讚賞，謝謝！

Answer 1

您可以添加UNION ALL以獲得每個全區共有SUM()

SELECT Store, MEX, USA 
FROM [Sales] 
PIVOT ( 
     SUM(Sales) 
     FOR Region IN ([MEX], [USA]) 
) AS SalesPerRegion 

UNION ALL 

SELECT 'Total', Sum(MEX), Sum(USA) 
FROM 
(
    SELECT Store, MEX, USA 
    FROM [Sales] 
    PIVOT ( 
      SUM(Sales) 
      FOR Region IN ([MEX], [USA]) 
    ) AS SalesPerRegion 
) x
