Hoe krijg ik het aantal zondagen van zes weken met behulp van de Weekno in SQL Server 2008?

Als u datumwaarden wilt kunnen doorgeven om de gegevens te krijgen die aan uw criteria voldoen, dan voor dit type PIVOT u moet een dynamische SQL-oplossing gebruiken die lijkt op deze:

DECLARE @cols AS NVARCHAR(MAX),
    @colsRollup AS NVARCHAR(MAX),
    @query  AS NVARCHAR(MAX),
    @StartDate DateTime,
    @EndDate DateTime

Set @StartDate = '10-08-2012 00:00:00.000'
Set @EndDate = '11-18-2012 23:59:59.000'

select @cols = STUFF((SELECT ',' + QUOTENAME(WeekEnd) 
                    from
                    (
                      select DatePart(wk, I01.[SPGI01_CREATE_S]) WeekEnd
                      from [SUPER-G].[dbo].[CSPGI01_ASN_ACCURACY]
                      where I01.[SPGI01_CREATE_S] between @StartDate AND @EndDate
                    ) src
                    group by WeekEnd
                    order by WeekEnd desc
            FOR XML PATH(''), TYPE
            ).value('.', 'NVARCHAR(MAX)') 
        ,1,1,'')

select @colsRollup = STUFF((SELECT ', Sum(' + QUOTENAME(WeekEnd) +') as WeekNo'+Cast(Weekend as varchar(2))
                    from
                    (
                      select DatePart(wk, I01.[SPGI01_CREATE_S]) WeekEnd
                      from [SUPER-G].[dbo].[CSPGI01_ASN_ACCURACY]
                      where I01.[SPGI01_CREATE_S] between @StartDate AND @EndDate
                    ) src
                    group by WeekEnd
                    order by WeekEnd desc
            FOR XML PATH(''), TYPE
            ).value('.', 'NVARCHAR(MAX)') 
        ,1,1,'')

set @query = '

execute(@query)
