複数の列をピボットするクエリ

Question

正しいレイアウトではなく、必要な出力を生成するクエリがあります。私はグループとしてピボットされた列のいくつかを持っている必要がありますが、それを行う方法を理解することはできません。次のように

クエリは次のとおりです。

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'; 

はこれが返されます。

|varchar(100)  |char(2) |int   |int  |varchar(10)| 
|--------------------|-----------|--------------|---------|-----------| 
|DocumentName  |PackageName|ContainerCount|PageCount|Media  | 
|--------------------|-----------|--------------|---------|-----------| 
|Invoices17_05_26.xml|01   |   1758|  2024|A   |

|Invoices17_05_30.xml|01   |   2757|  3336|A   | 
|Invoices17_05_30.xml|30   |   626|  2101|Email  |

|Stmts-17_05_01.xml |30   |   2888|  3267|Email  | 

をしかし、私はこのレイアウトを持つように出力を必要とする：

|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 |

私はバリエーションを試してみました以下のうち、役に立たないもの：

Answer 1

ダイナミック（つまり、数多くのPackageNameの）

おそらく最も簡単なの

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

はこれを試してみてください...
複数の列をピボットしますが、動的ではありません。

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

ORDER BY DocumentName
