如何动态空字段添加为列在SQL Server

Question

我有动态透视列的查询， 我需要工会也有我的grandtotal在底部， 问题是列在底部数成为联合不等于具有数据透视列的列数。我如何将列添加到我的grandtotal列中以在pivot列上进行联合，以便它们可以联合？

Answer 1

做到这一点，最简单的方法是用整数值设置为变量来计数@sizenameS和@DownDownDown条目数。然后，使用REPLICATE(''''',', number)。

开始通过声明两个int变量：

DECLARE @countS INT 
DECLARE @countD INT 

店创建列定义后直接记录到这些变量的数目：

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 

做同样的事情@DownDownDown

而且，您的最终SQL语句将为：

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'
