動態列的水平總和

Question

我正在嘗試獲取報表的水平總和。目前使用動態查詢和數據透視表。下面是我的代碼

聲明@cols爲nvarchar（最大） 聲明@pvt_cols爲nvarchar（最大） 聲明@sqlquery爲nvarchar（最大）

select @cols= Coalesce(@cols+',','') 
    + 'Coalesce([' +MonthYR+ '],0) AS [' + MonthDescription +'] ' 
      ,@pvt_cols=coalesce(@pvt_cols +',','') +' ['+[MonthYR] +']' 
from @Calendar 
where CASDT between '20110401' and '20111230' (generates column with month headers) 

print @cols  
print @pvt_cols 
print '--------------------' 


Set @sqlquery='Select ProdDesc,'+@cols + ',Total 
      from (Select ProdDesc, 
        MonthYr, 
        NetAmount, 
        SUM(NetAmount) over (partition by ProdDesc) as Total 
      from #Comtempt1 
      ) as dat 
        pivot(
      SUM(NetAmount) for MonthYr in 
      (' + @pvt_cols + '))pvt' 

print @sqlquery 

exec sp_executesql @sqlquery 

我能夠得到總，但它顯示的總爲整個記錄，而我只需要根據用戶輸入的日期得到總數。

declare @cols nvarchar(max) declare @pvt_cols nvarchar(max) declare @sqlquery nvarchar(max) 
declare @total nvarchar(max) 
select @cols= Coalesce(@cols+',','') 
    + 'Coalesce([' +MonthYR+ '],0) AS [' + MonthDescription +'] ' 
      ,@pvt_cols=coalesce(@pvt_cols +',','') +' ['+[MonthYR] +']' 
      ,@total= Coalesce(@total+'+','') + 'Coalesce([' +MonthYR+ '],0)' 
from @Calendar 
where CASDT between '20110401' and '20111230' (generates column with month headers) 

print @cols  
print @pvt_cols 
print '--------------------' 


Set @sqlquery='Select ProdDesc,'+@cols + ',' + @Total + ' Total 
      from (Select ProdDesc, 
        MonthYr, 
        NetAmount, 
        SUM(NetAmount) over (partition by ProdDesc) as Total 
      from #Comtempt1 
      ) as dat 
        pivot(
      SUM(NetAmount) for MonthYr in 
      (' + @pvt_cols + '))pvt' 

print @sqlquery 

exec sp_executesql @sqlquery
