Aracın hesaplanması

Question

Araç sürüşünü hesaplamak istiyorum ama problemle karşı karşıyayım. Hiçbir Groupby çalışmıyor.

select z.ZoneId, o.ObjectId,o.Number,o.Comment,z.Name StartTrip,zs.TimeFirst,zs.Inside,z.ZoneGroupId 

from dbo.Object o join 
dbo.GroupObject gobj on o.ObjectId = gobj.ObjectId join 
dbo.[Group] g on gobj.GroupId=g.GroupId join 
dbo.[ZoneState] zs on o.ObjectId=zs.ObjectId join 
dbo.[Zone] z on zs.ZoneId=z.ZoneId 
where (z.ZoneGroupId=1096 OR z.ZoneGroupId=1095) and o.ObjectId=3414 and (convert(date,zs.TimeFirst)>='2016/2/15') and (convert(date,zs.TimeFirst)<='2016/3/24') 

ORDER BY o.Number
