Question

集團

我試圖轉動我的一些行，目前我的查詢是這樣的：

SELECT count(distinct users.userName) as TotalUsers, products.productNameCommon, employees.Division, products.productType 
FROM FlexLM_users users 
INNER JOIN Org.Employees employees ON employees.Username=users.userName 
INNER JOIN FlexLM_history history ON users.userID=history.userID 
INNER JOIN FlexLM_products products ON products.productID=history.productID 
where products.productType = 'Base' 
GROUP BY products.productNameCommon, employees.Division, products.productType 
ORDER BY users DESC 

，並把該：

TotalUsers| productNameCommon | Division   | productType 
------------------------------------------------------------------------ 
16  | Standard   | Disease Control  | base 
12  | Basic    | Epidemiology   | base 
10  | Standard   | Prevention   | base 
8   | Advanced   | Epidemiology   | base 
6   | Basic    | Disease Control  | base 
2   | Advanced   | Prevention   | base 

我所希望做的是這樣的：

Division  | Basic | Standard | Advanced | TotalUsers 
---------------------------------------------------------- 
Disease Control| 6 | 16 | 0  | 22 
Epidemiology | 12 | 0  | 8  | 20 
Prevention  | 0 | 10  | 2  | 12 

Answer 1

SELECT Division 
    , ISNULL([Basic] , 0) AS [Basic] 
    , ISNULL([Standard], 0) AS [Standard] 
    , ISNULL([Advanced], 0) AS [Advanced] 
    , ISNULL([Basic] , 0) 
     + ISNULL([Standard], 0) 
     + ISNULL([Advanced], 0) AS TotalUsers 

FROM (
     SELECT TotalUsers , productNameCommon , Division 
     FROM ( 
         -- Your Existing Query here 
      )a  
    ) t 
PIVOT (
     SUM (TotalUsers) 
     FOR productNameCommon 
     IN ([Basic], [Standard] , [Advanced]) 
    ) p
