在SQL数据透视表的“总计”列中获取空值

Question

我有一个查询，该查询返回给我一个cloumn中的类别数，而其他列为动态列，它们给了我开始日期和结束日期之间的月份，并且此列向我返回了当月所售类别的数量。

我想在查询的行末添加总计

这是我的查询

    DECLARE @cols AS NVARCHAR(MAX),
            @query  AS NVARCHAR(MAX),
            @subtotal AS FLOAT,
            @startdate as datetime,
            @enddate as datetime
            DECLARE @ColumnsRollup AS VARCHAR (MAX)

            set @startdate = '1-Mar-2014'
            set @enddate =   '1-Aug-2014'

;with cte (StartDate, EndDate) as
(
    select min(@startdate) StartDate, max(@enddate) EndDate    
    union all
    select dateadd(mm, 1, StartDate), EndDate
    from cte
    where StartDate < EndDate
) 
select  StartDate
into #tempDates
from cte 


select @cols =  STUFF((SELECT distinct ',' + QUOTENAME(convert(CHAR(10), StartDate, 120)) 
                    from #tempDates
            FOR XML PATH(''), TYPE
            ).value('.', 'NVARCHAR(MAX)') 
        ,1,1,'') +  ',[Total]' 






SET  @query =           'select  ledger_name,
                        ' + @cols + '                        
                        from
                        (
                        SELECT 


                       CASE WHEN (GROUPING(ledger_name) = 1) THEN ''Grand Total''
                       ELSE ledger_name END AS ledger_name,


                       ISNULL(SUM(amount),0) Amount, 

                       CASE WHEN (GROUPING(StartDate) = 1) THEN ''Total''
                       ELSE convert(CHAR(10), StartDate, 120) END StartDate

                       FROM #tempDates d
                       left join Rs_Ledger_Master AS LM on  d.StartDate between '''+convert(varchar(10), @startdate, 120)+''' and '''+convert(varchar(10), @enddate, 120)+'''                      
                       LEFT OUTER JOIN RS_Payment_Master AS PM ON PM.ledger_code = LM.ledger_code and  month(paid_date) = month(StartDate) and  year(paid_date) = year(StartDate) 
                       group by 
                       ledger_name,StartDate WITH ROLLUP              
                       ) d
                        pivot
                        (
                          SUM(Amount)
                          for StartDate in (' + @cols + ')
                        ) p                                                                 
                        ORDER BY CASE WHEN ledger_name = ''Grand Total'' THEN 1 END'
        execute sp_executesql @query;
        drop table #tempDates

Answer 1

我认为您可以做的是，尝试在内部查询中使用ROLLUP选项，该查询实际上为SUM（Amount）返回附加行，您可以将其称为Total并将此列添加到列列表中。

这是我认为您需要做的更改

在栏列表末尾添加总栏

SET @cols= @cols + ',[Total]'

将汇总选项添加到内部查询中。 请注意，需要case语句才能将文本更改为该行的总计。

DECLARE @cols AS NVARCHAR(MAX),
            @query  AS NVARCHAR(MAX),
            @subtotal AS FLOAT,
            @startdate as datetime,
            @enddate as datetime
            DECLARE @ColumnsRollup AS VARCHAR (MAX)

            set @startdate = '1-Mar-2014'
            set @enddate =   '1-Aug-2014'

;with cte (StartDate, EndDate) as
(
    select min(@startdate) StartDate, max(@enddate) EndDate    
    union all
    select dateadd(mm, 1, StartDate), EndDate
    from cte
    where StartDate < EndDate
) 
select  StartDate
into #tempDates
from cte 


select @cols =  STUFF((SELECT distinct ',' + QUOTENAME(convert(CHAR(10), StartDate, 120)) 
                    from #tempDates
            FOR XML PATH(''), TYPE
            ).value('.', 'NVARCHAR(MAX)') 
        ,1,1,'') +  ',[Total]' 


SET  @query =           'select  ledger_name,
                        ' + @cols + '                        
                        from
                        (
                        SELECT 


                       ledger_name,


                       ISNULL(SUM(amount),0) Amount, 

                       CASE WHEN (GROUPING(StartDate) = 1) THEN ''Total''
                       ELSE convert(CHAR(10), StartDate, 120) END StartDate

                       FROM #tempDates d
                       left join Rs_Ledger_Master AS LM on  d.StartDate between '''+convert(varchar(10), @startdate, 120)+''' and '''+convert(varchar(10), @enddate, 120)+'''                      
                       LEFT OUTER JOIN RS_Payment_Master AS PM ON PM.ledger_code = LM.ledger_code and  month(paid_date) = month(StartDate) and  year(paid_date) = year(StartDate) 
                       group by 
                       ledger_name,StartDate WITH ROLLUP              
                       ) d
                        pivot
                        (
                          SUM(Amount)
                          for StartDate in (' + @cols + ')
                        ) p      
                        WHERE ledger_name IS NOT NULL
                         UNION ALL
                        select  ledger_name,
                        ' + @cols + ' FROM
                       (SELECT ''Grand Total'' AS ledger_name,
                       ISNULL(SUM(amount),0) Amount, 
                       CASE WHEN (GROUPING(StartDate) = 1) THEN ''Total''
                       ELSE convert(CHAR(10), StartDate, 120) END StartDate

                       FROM #tempDates d
                       left join Rs_Ledger_Master AS LM on  d.StartDate between '''+convert(varchar(10), @startdate, 120)+''' and '''+convert(varchar(10), @enddate, 120)+'''                      
                       LEFT OUTER JOIN RS_Payment_Master AS PM ON PM.ledger_code = LM.ledger_code and  month(paid_date) = month(StartDate) and  year(paid_date) = year(StartDate) 
                       group by StartDate WITH ROLLUP              
                       ) d
                       pivot
                       (
                         SUM(Amount)
                         for StartDate in (' + @cols + ')
                       ) p


                        '
        print @query
        execute sp_executesql @query;
        drop table #tempDates

您需要附加所有并集以获取最后的摘要行
