在SQL数据透视表的“总计”列中获取空值

Question

I have the query which returning me the number of categories in one cloumn and other column are dynamic column they are giving me the the months between start date & end date and this column are returning me the amount of the categories sold on that month.

I want to add the Grand Total at the end of the row in the query

Here's My Query

    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 + '

                       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)+'''

                       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

I think what you can do is, try to use the ROLLUP option in your inner query, which actually returns addtional row for the SUM(Amount), which you can call as Total and add this column to your column list.

Here is the change what I think you need to do

Add total column at the end of your column list

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

Add the rollup option to your inner query. Note that, the case statement is required to change the text as total for the row.

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)+'''

                       group by 
                       ledger_name,StartDate WITH ROLLUP              
                       ) d
                        pivot
                        (
                          SUM(Amount)

                        ) p

                       group by StartDate WITH ROLLUP

                       ) p


                        '
        print @query
        execute sp_executesql @query;

You need additional union all to get the last summary row

You can refer the following article for using ROLLUP http://technet.microsoft.com/en-us/library/ms189305(v=sql.90).aspx
