需要SQL數據透視幫助，因爲我沒有聚合列

Question

我有我創建的以下視圖看起來像這張表。

Create Table #Temptable(
[Week number] int, 
[Did Not meet minimum] int, 
[Met minimum] int, 
[exceeded minimum] int); 

insert into #Temptable([Week number],[Did Not meet minimum],[Met minimum],[exceeded minimum]) 
values 
(3,161,4,18), 
(4,165,1,24), 
(5,166,0,10) 

我想輸出爲三行，以便我可以按周創建趨勢報告。我可以填充臨時表來獲得所需的結果，但我想看看是否有更好的解決方案。

Label, week3, week4, week5 
Did not meet minimum, 161, 165, 166 
Met minimum, 4, 1, 0 
Exceeded minimum, 18, 24, 10 

如果這從這個數據集是不可能的，我也有源代碼行項目詳細信息的視圖是從創建。該數據集看起來像這樣

techname,machinename,installdate,weeknumber 

我提出，通過techname和週數合計3個標量函數，這樣我可以讓沒有滿足，滿足，並超過了每星期的安裝次數。

預先感謝您。

從StuartLC得到迴應後，我開始製作我自己的動態版本我很接近，但是當我發佈一個回覆時，另一個人發佈了一個工作版本。爲了大家的利益，這裏是我把它放在一起的示例代碼，但不起作用。如果我複製錯誤文本並只選擇輸出的查詢，它可以正常工作。

DECLARE @cols AS NVARCHAR(MAX), 
@query AS NVARCHAR(MAX) 
SET @cols = STUFF((SELECT distinct ',' + QUOTENAME(c.[week number]) 
     FROM SummarisedWeeklysums c 
     FOR XML PATH(''), TYPE 
     ).value('.', 'NVARCHAR(MAX)') 
    ,1,1,'') 

set @query = 'SELECT Criteria, '+ @Cols +' FROM 
(
SELECT 
    * 
FROM 
    SummarisedWeeklysums 
UNPIVOT 
(
    CriteriaCount 
    for Criteria in ([Did Not meet minimum],[Met minimum],[exceeded minimum]) 
) unpvt 
) X 
    PIVOT 
    (
SUM(CriteriaCount) 
for [Week Number] IN ('+@Cols+') 
)pvt' 

execute @query 

Answer 1

的是基於StuartLC答案和鏈接（信用給你）的可擴展性，如果額外幾周在將來添加：

DECLARE @cols AS NVARCHAR(MAX); 
DECLARE @query AS NVARCHAR(MAX); 
select @cols = STUFF((SELECT distinct ',' + 
         QUOTENAME('Week'+cast([Week Number] as varchar)) 
         FROM #Temptable 
         FOR XML PATH(''), TYPE 
        ).value('.', 'NVARCHAR(MAX)') 
         , 1, 1, ''); 
select @query = 
'SELECT * 
FROM 
(
    SELECT 
      ''Week''+cast([Week number] as varchar) as [Week number] , CriteriaCount , Criteria 
    FROM 
     #Temptable 
    UNPIVOT 
    (
     CriteriaCount 
     for Criteria in ([Did Not meet minimum],[Met minimum],[exceeded minimum]) 
    ) unpvt 
) X 
PIVOT 
(
SUM(CriteriaCount) 
for [Week Number] in (' + @cols + ') 
)pvt ;'; 
execute(@query); 

下面是相同的代碼，用結果移動到一個臨時表（按照user3275​​636的要求），然後顯示：

DECLARE @cols AS NVARCHAR(MAX); 
DECLARE @query AS NVARCHAR(MAX); 
select @cols = STUFF((SELECT distinct ',' + 
         QUOTENAME('Week'+cast([Week Number] as varchar)) 
         FROM #Temptable 
         FOR XML PATH(''), TYPE 
        ).value('.', 'NVARCHAR(MAX)') 
         , 1, 1, ''); 
select @query = 
'select * into ##temp1 from (SELECT * 
FROM 
(
    SELECT 
      ''Week''+cast([Week number] as varchar) as [Week number] , CriteriaCount , Criteria 
    FROM 
     #Temptable 
    UNPIVOT 
    (
     CriteriaCount 
     for Criteria in ([Did Not meet minimum],[Met minimum],[exceeded minimum]) 
    ) unpvt 
) X 
PIVOT 
(
SUM(CriteriaCount) 
for [Week Number] in (' + @cols + ') 
)pvt) as combi;'; 
execute(@query); 
select * from ##temp1; 

Answer 2

這非常類似於我answer here - 基本上你正在尋找一個完整的轉置。這可以用一個逆透視來完成，然後通過樞軸：

SELECT Criteria, [3] as Week3, [4] AS Week4, [5] AS Week5 
FROM 
(
    SELECT 
     * 
    FROM 
     #Temptable 
    UNPIVOT 
    (
     CriteriaCount 
     for Criteria in ([Did Not meet minimum],[Met minimum],[exceeded minimum]) 
    ) unpvt 
) X 
PIVOT 
(
SUM(CriteriaCount) 
for [Week Number] IN ([3],[4],[5]) 
)pvt;

另外，如果你需要爲一羣不明星期做這個（或標準，我猜的），你可以看看在answer here它使用動態sql來建立列和執行樞紐。
