PIVOT SQL - 如何顯示我們正在旋轉的列？

Question

我寫了我的數據透視SQL，它正在工作。當前的SQL語句如下，我將展示如何返回數據的示例。我需要添加一列，這是它的炸彈：

Select 
    ProductGroup, 
    Origin, 
    Destination, 
    [YEAR], 
    Isnull([Jan],0) as "Jan", 
    isnull([Feb],0) as "Feb", 
    isnull([Mar],0) as "Mar", 
    isnull([Apr],0) as "Apr", 
    isnull([May],0) as "May", 
    isnull([Jun],0) as "Jun", 
    isnull([Jul],0) as "Jul", 
    isnull([Aug],0) as "Aug", 
    isnull([Sep],0) as "Sep", 
    isnull([Oct],0) as "Oct", 
    isnull([Nov],0) as "Nov", 
    isnull([Dec],0) as "Dec" 
FROM 
(
SELECT 
    p.ProductGroup, 
    S.Origin, 
    S.FinalDest AS Destination, 
    SUBSTRING('Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec', (Month(boldate) * 4) - 3, 3) as MonthAbreviated, 
    Year(BolDate) AS [Year], 
    Count(*) AS [Total] 
-- ,COUNT(S.Purchase#) AS [TheTotal] 
    FROM 
     dbo.Contracts c INNER JOIN dbo.Purchases pu ON c.[Contract#] = pu.[Contract#] 
     INNER JOIN dbo.Products as p ON pu.Product = p.Product 
     INNER JOIN dbo.Shipments S ON pu.[Purchase#] = S.[Purchase#] 
WHERE 
    Year(BolDate)<>1994 AND 
    pu.Cancelled=0 AND S.[Status]='L' 
GROUP BY p.ProductGroup, S.Origin, S.FinalDest,Year(BolDate), SUBSTRING('Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec', (Month(boldate) * 4) - 3, 3) 

) AS SourceTable 
PIVOT 
(
sum(Total) 
FOR MonthAbreviated IN ([Jan],[Feb],[Mar],[Apr],[May],[Jun],[Jul],[Aug],[Sep],[Oct],[Nov],[Dec]) 
) AS PivotTable 

實例結果：

ProductGroup Origin Destination YEAR  Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec 
Nail   Bath Toronto  2012  0 0 0 10 1 0 0 0 0 0 0 0 
Nail   Cedars Toronto  2011  0 0 0 0 0 0 0 0 0 0 25 53 

我需要補充的是顯示總的行的一列。例如，第1行是11，第2行是78.在我的選擇中，我認爲只需在查詢中添加「總計」即可，但每次都會收到無效的列。如果您希望該行的總，你可以簡單地添加列在一起，得到總

Msg 207, Level 16, State 1, Line 6 Invalid column name 'Total'.

Select 
    ProductGroup, 
    Origin, 
    Destination, 
    [YEAR], 
    [Total], 
    Isnull([Jan],0) as "Jan", 
    isnull([Feb],0) as "Feb", 
    isnull([Mar],0) as "Mar", 
    isnull([Apr],0) as "Apr", 
    isnull([May],0) as "May", 
    isnull([Jun],0) as "Jun", 
    isnull([Jul],0) as "Jul", 
    isnull([Aug],0) as "Aug", 
    isnull([Sep],0) as "Sep", 
    isnull([Oct],0) as "Oct", 
    isnull([Nov],0) as "Nov", 
    isnull([Dec],0) as "Dec" 
FROM 
(
SELECT 
    p.ProductGroup, 
    S.Origin, 
    S.FinalDest AS Destination, 
    SUBSTRING('Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec', (Month(boldate) * 4) - 3, 3) as MonthAbreviated, 
    Year(BolDate) AS [Year], 
    Count(*) AS [Total] 
-- ,COUNT(S.Purchase#) AS [TheTotal] 
    FROM 
     dbo.Contracts c INNER JOIN dbo.Purchases pu ON c.[Contract#] = pu.[Contract#] 
     INNER JOIN dbo.Products as p ON pu.Product = p.Product 
     INNER JOIN dbo.Shipments S ON pu.[Purchase#] = S.[Purchase#] 
WHERE 
    Year(BolDate)<>1994 AND 
    pu.Cancelled=0 AND S.[Status]='L' 
GROUP BY p.ProductGroup, S.Origin, S.FinalDest,Year(BolDate), SUBSTRING('Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec', (Month(boldate) * 4) - 3, 3) 

) AS SourceTable 
PIVOT 
(
sum(Total) 
FOR MonthAbreviated IN ([Jan],[Feb],[Mar],[Apr],[May],[Jun],[Jul],[Aug],[Sep],[Oct],[Nov],[Dec]) 
) AS PivotTable 

Answer 1

：

換句話說，我得到這個錯誤。所以，你會希望添加以下行：

([Jan] + [Feb] + [Mar] + [Apr] + [May] + [Jun] + [Jul] + [Aug] + [Sep] + [Oct] + [Nov] + [Dec]) as Total 

讓你查詢：

Select 
    ProductGroup, 
    Origin, 
    Destination, 
    [YEAR], 
    Isnull([Jan],0) as "Jan", 
    isnull([Feb],0) as "Feb", 
    isnull([Mar],0) as "Mar", 
    isnull([Apr],0) as "Apr", 
    isnull([May],0) as "May", 
    isnull([Jun],0) as "Jun", 
    isnull([Jul],0) as "Jul", 
    isnull([Aug],0) as "Aug", 
    isnull([Sep],0) as "Sep", 
    isnull([Oct],0) as "Oct", 
    isnull([Nov],0) as "Nov", 
    isnull([Dec],0) as "Dec", 
    ([Jan] + [Feb] + [Mar] + [Apr] + [May] + [Jun] + [Jul] + [Aug] + [Sep] + [Oct] + [Nov] + [Dec]) as Total 
FROM 
(
SELECT 
    p.ProductGroup, 
    S.Origin, 
    S.FinalDest AS Destination, 
    SUBSTRING('Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec', (Month(boldate) * 4) - 3, 3) as MonthAbreviated, 
    Year(BolDate) AS [Year], 
    Count(*) AS [Total] 
-- ,COUNT(S.Purchase#) AS [TheTotal] 
    FROM 
     dbo.Contracts c INNER JOIN dbo.Purchases pu ON c.[Contract#] = pu.[Contract#] 
     INNER JOIN dbo.Products as p ON pu.Product = p.Product 
     INNER JOIN dbo.Shipments S ON pu.[Purchase#] = S.[Purchase#] 
WHERE 
    Year(BolDate)<>1994 AND 
    pu.Cancelled=0 AND S.[Status]='L' 
GROUP BY p.ProductGroup, S.Origin, S.FinalDest,Year(BolDate), SUBSTRING('Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec', (Month(boldate) * 4) - 3, 3) 

) AS SourceTable 
PIVOT 
(
sum(Total) 
FOR MonthAbreviated IN ([Jan],[Feb],[Mar],[Apr],[May],[Jun],[Jul],[Aug],[Sep],[Oct],[Nov],[Dec]) 
) AS PivotTable 

Answer 2

作爲替代方案，你也可以使用ROLLUP

你需要

• 添加一個case語句給彙總的「名稱」

  CASE WHEN (GROUPING(Substring(DateName(m,boldate),1,3) = 1) Then 'Total' 
      ELSE Substring(DateName(m,boldate),1,3) 
  END as MonthAbreviated, 
  

• 添加彙總到組由

  GROUP BY 
  .... 
  Substring(DateName(m,boldate),1,3) 
  WITH ROLLUP 
  

• 在有

  HAVING 
      GROUPING (Year(BolDate) = 0) 
  

它包含在你的第

... [Nov],[Dec], [Total]) 

• 排除所有其他彙總分組

注意我已經修改了你的MonthAbreviated語法來縮短它，我不得不改變別名COUNT（*），因爲它具有相同的名稱作爲迴轉值

Select 
    ProductGroup, 
    Origin, 
    Destination, 
    [YEAR], 
    Isnull([Jan],0) as "Jan", 
    isnull([Feb],0) as "Feb", 
    isnull([Mar],0) as "Mar", 
    isnull([Apr],0) as "Apr", 
    isnull([May],0) as "May", 
    isnull([Jun],0) as "Jun", 
    isnull([Jul],0) as "Jul", 
    isnull([Aug],0) as "Aug", 
    isnull([Sep],0) as "Sep", 
    isnull([Oct],0) as "Oct", 
    isnull([Nov],0) as "Nov", 
    isnull([Dec],0) as "Dec", 
    isnull([Total],0) as "Total" 
FROM 
(
SELECT 
    p.ProductGroup, 
    S.Origin, 
    S.FinalDest AS Destination, 
    CASE WHEN (GROUPING(Substring(DateName(m,boldate),1,3) = 1) Then 'Total' 
     ELSE Substring(DateName(m,boldate),1,3) 
    END as MonthAbreviated, 
    Year(BolDate) AS [Year], 
    Count(*) AS [Kount] 
    FROM 
     dbo.Contracts c INNER JOIN dbo.Purchases pu ON c.[Contract#] = pu.[Contract#] 
     INNER JOIN dbo.Products as p ON pu.Product = p.Product 
     INNER JOIN dbo.Shipments S ON pu.[Purchase#] = S.[Purchase#] 
WHERE 
    Year(BolDate)<>1994 AND 
    pu.Cancelled=0 AND S.[Status]='L' 
GROUP BY 
    p.ProductGroup, 
    S.Origin, 
    S.FinalDest,Year(BolDate), 
    Substring(DateName(m,boldate),1,3) 
    WITH ROLLUP 
HAVING 
    GROUPING (Year(BolDate) = 0) 


) AS SourceTable 
PIVOT 
(
sum(Kount) 
FOR MonthAbreviated IN ([Jan],[Feb],[Mar],[Apr],[May],[Jun],[Jul],[Aug],[Sep],[Oct],[Nov],[Dec], [Total]) 
) AS PivotTable
