I have a query to measure delivery performance. Using
DATEDIFF ( DAY , SIH.[Order Date], SIL.[Shipment Date] ) AS [Ship Days],
this gives me a value including weekends.
How do I exclude the weekends?
Thanks.

that was fast reading.. ;)

here is the wanted solutions just replace @startdate, @enddate


select datediff(dd,@startdate,@enddate)-2*datediff(ww,@startdate,@enddate)
+ case when datepart(dw,@startdate)=1 or datepart(dw,@enddate)=7 then -1
when datepart(dw,@startdate)=7 or datepart(dw,@enddate)=1 then +1
else 0 end
