查詢，樞軸多列

Question

我有一個查詢，產生所需的輸出，但不是在正確的佈局。我需要將一些列作爲一個組來旋轉，但不知道如何去做。

查詢如下：

SELECT Line.DocumentName 
     ,Package.PackageName 
     ,Package.ContainerCount 
     ,Package.PageCount 
     ,m.Name Media 
    FROM Invoice i 
    JOIN Section s ON i.InvoiceDate = s.InvoiceDate 
    JOIN Line l ON s.InvoiceDate = l.InvoiceDate AND s.DocumentTypeID = l.DocumentTypeID 
    JOIN Package p ON l.InvoiceDate = p.InvoiceDate AND l.DocumentTypeID = p.DocumentTypeID AND l.DocumentDate = p.DocumentDate 
    JOIN MediaType m ON p.MediaTypeID = m.Id 
    WHERE i.InvoiceDate = '6/1/2017'; 

這將返回：

|varchar(100)  |char(2) |int   |int  |varchar(10)| 
|--------------------|-----------|--------------|---------|-----------| 
|DocumentName  |PackageName|ContainerCount|PageCount|Media  | 
|--------------------|-----------|--------------|---------|-----------| 
|Invoices17_05_26.xml|01   |   1758|  2024|A   | 
|Invoices17_05_26.xml|30   |   382|  1728|Email  | 
|Invoices17_05_30.xml|01   |   2757|  3336|A   | 
|Invoices17_05_30.xml|30   |   626|  2101|Email  | 
|Credits17_05_01.xml |01   |   1346|  1488|A   | 
|Credits17_05_01.xml |30   |   390|  451|Email  | 
|Credits17_05_08.xml |01   |    0|  0|C   | 
|Credits17_05_08.xml |30   |   353|  408|Email  | 
|Stmts-17_05_01.xml |01   |   14796| 15299|B   | 
|Stmts-17_05_01.xml |30   |   2888|  3267|Email  | 

不過，我需要的輸出有這樣的佈局：

|DocumentName  |01 ContainerCount|01 PageCount|01 Media|30 ContainerCount|30 PageCount|30 Media| 
|--------------------|-----------------|------------|--------|-----------------|------------|--------| 
|Invoices17_05_26.xml|    1758|  2024|A  |    382|  1728|Email | 
|Invoices17_05_30.xml|    2757|  3336|A  |    626|  2101|Email | 
|Credits17_05_01.xml |    1346|  1488|A  |    390|   451|Email | 
|Credits17_05_08.xml |    0|   0|C  |    353|   408|Email | 
|Stmts-17_05_01.xml |   14796|  15299|B  |    2888|  3267|Email | 

我已經試過變化以下，無果：

Answer 1

我不清楚你是否需要動態（即衆多PACKAGENAME）

也許最簡單的將是包裝你的初始查詢中的最後一個條件匯聚

例

Select DocumentName 
     ,[01 ContainerCount] = sum(case when PackageName='01' then ContainerCount end) 
     ,[01 PageCount]  = sum(case when PackageName='01' then PageCount end) 
     ,[01 Media]   = max(case when PackageName='01' then Media end) 
     ,[30 ContainerCount] = sum(case when PackageName='30' then ContainerCount end) 
     ,[30 PageCount]  = sum(case when PackageName='30' then PageCount end) 
     ,[30 Media]   = max(case when PackageName='30' then Media end) 
From (
     SELECT Line.DocumentName 
       ,Package.PackageName 
       ,Package.ContainerCount 
       ,Package.PageCount 
       ,m.Name Media 
      FROM Invoice i 
      JOIN Section s ON i.InvoiceDate = s.InvoiceDate 
      JOIN Line l ON s.InvoiceDate = l.InvoiceDate AND s.DocumentTypeID = l.DocumentTypeID 
      JOIN Package p ON l.InvoiceDate = p.InvoiceDate AND l.DocumentTypeID = p.DocumentTypeID AND l.DocumentDate = p.DocumentDate 
      JOIN MediaType m ON p.MediaTypeID = m.Id 
      WHERE i.InvoiceDate = '6/1/2017' 
     ) A 
Group By DocumentName

試試這個...
它樞軸多列，不動態雖然

SELECT 
DocumentName 
, [01 ContainerCount] = SUM([P1CC1]) 
, [01 PageCount] = SUM([P1PC1]) 
, [01 Media] = MAX([P1M1]) 
, [30 ContainerCount] = SUM([P30CC2]) 
, [30 PageCount] = SUM([P30PC2]) 
, [30 Media] = MAX([P30M2]) 
FROM (

SELECT 
    A.DocumentName AS DocumentName, 
    ContainerCount, 
    [PageCount], 
    Media 
    ,A.PackageName + 'CC' + CAST(DENSE_RANK() OVER (PARTITION BY A.DocumentName ORDER BY A.PackageName ASC) AS NVARCHAR) AS [PkgNumberCC] 
    ,A.PackageName + 'PC' + CAST(DENSE_RANK() OVER (PARTITION BY A.DocumentName ORDER BY A.PackageName ASC) AS NVARCHAR) AS [PkgNumberPC] 
    ,A.PackageName + 'M' + CAST(DENSE_RANK() OVER (PARTITION BY A.DocumentName ORDER BY A.PackageName ASC) AS NVARCHAR) AS [PkgNumberM] 
    FROM (
     SELECT Line.DocumentName 
       ,Package.PackageName 
       ,Package.ContainerCount 
       ,Package.PageCount 
       ,m.Name Media 
      FROM Invoice i 
      JOIN Section s ON i.InvoiceDate = s.InvoiceDate 
      JOIN Line l ON s.InvoiceDate = l.InvoiceDate AND s.DocumentTypeID = l.DocumentTypeID 
      JOIN Package p ON l.InvoiceDate = p.InvoiceDate AND l.DocumentTypeID = p.DocumentTypeID AND l.DocumentDate = p.DocumentDate 
      JOIN MediaType m ON p.MediaTypeID = m.Id 
      WHERE i.InvoiceDate = '6/1/2017' 
    ) A 
) AS query 
PIVOT (MAX(ContainerCount) 
     FOR [PkgNumberCC] IN ([P1CC1],[P30CC2])) AS Pivot1 
PIVOT (MAX([PageCount]) 
     FOR [PkgNumberPC] IN ([P1PC1],[P30PC2])) AS Pivot2 
PIVOT (MAX(Media) 
     FOR [PkgNumberM] IN ([P1M1],[P30M2])) AS Pivot3 
GROUP BY 
    DocumentName 
ORDER BY DocumentName
