Hello

How do I sum and get average of rows from this statement

--
SELECT DateDiff(dd,convert(datetime,invRecDate,103),convert(datetime,invToAdminPrepDT,103))-DateDiff(ww,convert(datetime,invRecDate,103),convert(datetime,invToAdminPrepDT,103))*2 AS Days FROM reportViewHQ WHERE invWorkshop = 'Fleet'
--

Thanks for your help
