I am trying to get the column value that is null but i am not able to do so.

What I have tried:

I have below query and it is giving all results including Null as well. But i need to filter on the basis of commented segmentIDs and i need null value as well. Don't require the Segments else than below filter(Commented Currently)

SQL

Select distinct SegmentID,Sum(distance) as TotalDistance from [dbo].[tblBookingContent] 
where Orgnization = 'REGERINGSKANSLIET' --and segmentid in ('LUX001S02','LUX001S11','SWE001S03','SWE001S09','SWE001S14','SWE001S20','SWE001S15','SWE001S23')
and IsV4 in (0,1) 
and departuredate between 
convert(datetime, '2016-07-01', 110) and 
convert(datetime, '2016-09-30', 110) and MPSS= 1
and BookingNumber not in (select BookingNumber from tblBookingContent where BookingStatus=1)
group by SegmentId

It seems easy, I'm not sure to understand weel but try this:

C#

Select distinct SegmentID,Sum(distance) as TotalDistance from [dbo].[tblBookingContent] 
where Orgnization = 'REGERINGSKANSLIET' 
and (segmentid is null or segmentid in ('LUX001S02','LUX001S11','SWE001S03','SWE001S09','SWE001S14','SWE001S20','SWE001S15','SWE001S23'))
and IsV4 in (0,1) 
and departuredate between 
convert(datetime, '2016-07-01', 110) and 
convert(datetime, '2016-09-30', 110) and MPSS= 1
and BookingNumber not in (select BookingNumber from tblBookingContent where BookingStatus=1)
group by SegmentId
