SQL Server數據透視表與計數和總和

Question

我想獲得一個SQL Server數據透視表的工作，使我可以計數，然後總和列數（總共6）。數據透視表的目的是爲任意數量的生產站點彙總在線問卷調查結果。有6個問題可以有3個結果值 - 目標，行動和失敗。我想要做的是計算每個問題的目標，行動和失敗數量，然後對每個問題進行總結。所以，例如，生產現場A可以有2個目標，2個動作和2個失敗。

我的理解是，SQL Server數據透視表可以提供此信息，然後可以在ASP.Net ReportViewer中顯示。下面是我的代碼，但它不能正常工作，並能與一些專家幫助做：

 SELECT PRODUCTION_Site, 
    [Target], 
    [Action], 
    [Fail] 
    FROM 
    (SELECT Production_Site, 
      SUM(Coding), 
      SUM(Measurable), 
      SUM(Appearance), 
      SUM(Aroma), 
      SUM(Flavour), 
      SUM(Texture) 
       FROM t_Pqe_Grocery 
       GROUP BY Production_Site) AS T 
      PIVOT 
     (
      COUNT(Coding) FOR Grocery_Packaging_And_Coding IN ([Target],[Action],[Fail]) 
      COUNT(Measurable) FOR Grocery_Measurable IN ([Target],[Action],[Fail]) 
      COUNT(Appearance) FOR Grocery_Appearance IN ([Target],[Action],[Fail]) 
      COUNT(Aroma) FOR Grocery_Aroma IN ([Target],[Action],[Fail]) 
      COUNT(Flavour) FOR Grocery_Flavour IN ([Target],[Action],[Fail]) 
      COUNT(Texture) FOR Grocery_Texture IN ([Target],[Action],[Fail])) AS P 

是否有辦法解決這，或者是透視表沒有解決辦法？

表是

Production_Site, 
Grocery_Packaging_And_Coding, 
Grocery_Measurable, 
Grocery_Appearance, 
Grocery_Aroma, 
Grocery_Flavour, 
Grocery_Texture 

表中數據將是這樣的：

Site A, Target, Action, Fail, Target, Target, Target 
Site B, Target, Action, Fail, Target, Target, Target 
Site C, Target, Target, Target, Target, Target, Target 
Site A, Target, Target, Target, Target, Target, Target 

我正在尋找的結果是

Production_Site | Target | Action | Fail 
Site A    10  1  1 
Site B    4  1  1 
Site C    6  0  0

一個執行此查詢更爲方便的方法將同時應用UNPIVOT和PIVOT函數：

select * 
from 
(
    select Production_Site, value 
    from t_Pqe_Grocery 
    unpivot 
    (
    value 
    for col in (Grocery_Packaging_And_Coding, Grocery_Measurable, 
       Grocery_Appearance, Grocery_Aroma, 
       Grocery_Flavour, Grocery_Texture) 
) unp 
) src 
pivot 
(
    count(value) 
    for value in ([Target], [Action], [Fail]) 
) piv 

見SQL Fiddle with Demo

的UNPIVOT需要你的列清單，並將其轉換爲多行，這使得它更容易算：

select Production_Site, value 
from t_Pqe_Grocery 
unpivot 
(
    value 
    for col in (Grocery_Packaging_And_Coding, Grocery_Measurable, 
       Grocery_Appearance, Grocery_Aroma, 
       Grocery_Flavour, Grocery_Texture) 
) unp 

逆透視結果：

| PRODUCTION_SITE | VALUE | 
---------------------------- 
|   Site A | Target | 
|   Site A | Action | 
|   Site A | Fail | 
|   Site A | Target | 
|   Site A | Target | 
|   Site A | Target | 
|   Site B | Target | 
|   Site B | Action | 
|   Site B | Fail | 
|   Site B | Target | 
|   Site B | Target | 
|   Site B | Target | 
|   Site C | Target | 
|   Site C | Target | 
|   Site C | Target | 
|   Site C | Target | 
|   Site C | Target | 
|   Site C | Target | 
|   Site A | Target | 
|   Site A | Target | 
|   Site A | Target | 
|   Site A | Target | 
|   Site A | Target | 
|   Site A | Target | 

然後將PIVOT應用於此將得到計數你需要爲每個PRODUCTION_SITE s。加入PIVOT後，結果爲：

| PRODUCTION_SITE | TARGET | ACTION | FAIL | 
-------------------------------------------- 
|   Site A |  10 |  1 | 1 | 
|   Site B |  4 |  1 | 1 | 
|   Site C |  6 |  0 | 0 |
