如何動態空字段添加爲列在SQL Server

Question

我有動態透視列的查詢， 我需要工會也有我的grandtotal在底部， 問題是列在底部數成爲聯合不等於具有數據透視列的列數。我如何將列添加到我的grandtotal列中以在pivot列上進行聯合，以便它們可以聯合？

Answer 1

做到這一點，最簡單的方法是用整數值設置爲變量來計數@sizenameS和@DownDownDown條目數。然後，使用REPLICATE(''''',', number)。

開始通過聲明兩個int變量：

DECLARE @countS INT 
DECLARE @countD INT 

店創建列定義後直接記錄到這些變量的數目：

SELECT @sizenameS = COALESCE(@sizenameS + ', ','') + QUOTENAME(SizeName) 
    FROM 
    ( select DISTINCT SIZESET.SizeSetID, SizeName 
    from SIZESET 
    left join SHIPMENTSIZESET ON SIZESET.SizeSetID = SHIPMENTSIZESET.SizeSetID 
    left join SHIPMENTSCHED on SHIPMENTSCHED.ShipmentSchedID = SHIPMENTSIZESET.ShipmentSchedID 
    left join DESIGN on DESIGN.DesignID = SIZESET.DesignID 
    left join ARTICLE on ARTICLE.DesignID = DESIGN.DesignID where ArticleNo = @article 
    )src2 
    ORDER BY SizeSetID 
    SET @countS = @@ROWCOUNT 

做同樣的事情@DownDownDown

而且，您的最終SQL語句將爲：

SET @JerryPogi = 'SELECT *, ('+ @DownDownDown + ') AS [Date Total] INTO #Pansamantala 
      FROM 
      (
       select DISTINCT ShipmentSched.ShipmentSchedId, CONVERT(varchar(10), StartDate, 110) as [Start Date], CONVERT(varchar(10), EndDate, 110) as [End Date], SizeName, Quantity 
       from SIZESET 
       left join SHIPMENTSIZESET ON SIZESET.SizeSetID = SHIPMENTSIZESET.SizeSetID 
       left join SHIPMENTSCHED on SHIPMENTSCHED.ShipmentSchedID = SHIPMENTSIZESET.ShipmentSchedID 
       left join DESIGN on DESIGN.DesignID = SIZESET.DesignID 
       left join ARTICLE on ARTICLE.DesignID = DESIGN.DesignID where ArticleNo = '''+@article+''' 
      ) JerryGwapo 
      PIVOT 
      (
       SUM(Quantity) 
       FOR SizeName 
       IN('+@sizenameS +') 
      ) JerryHot 
      ORDER BY [Start Date] 

      SELECT * FROM #Pansamantala 
      UNION ALL 
      SELECT '''','''',''Size Total'','+@ToTheLeft +', isnull(SUM([Date Total]),0) FROM #Pansamantala 
      UNION ALL 
      SELECT 
      '''', '''','''','+@price+','''' 
      union 
      select 
      '''','''',''''' + REPLICATE(',''''', @countS) + ',' +@grandtotal + ' from #pansamantala'
