DataClasses1DataContext db = new DataClasses1DataContext();
return (IQueryable)( from br in db.batch_ratejob
join from rj in db.ratejobs on br.ratejobkey equals rj.idinner
join from u in db.users on rj.userkey equals u.idinner
join from b in db.batchs on br.batchkey equals b.idinner
join from rp in db.rateprocesss on rp.batchkey equals b.id
group by br.batchkey, u.loginname
select new {br.batchkey, count(rj.id) as ratejobcreated,
(from a in db.RATEJOBs
join from b in db.batch_ratejobs
on b.ratejobkey equals a.id
where b.batchkey equals br.batchkey && completedflag equals 1 select new (COUNT(ID));)
as ratejobcompleted, u.loginname,COUNT(rp.id) as shipment_count });
