Linq to Entities Joins
- by Bob Avallone
I have a question about joins when using Linq to Entities. According to the documentation the use on the join without a qualifier performs like a left outer join. However when I execute the code below, I get a count returned of zero. But if I comment out the three join lines I get a count of 1. That would indicate that the join are acting as inner join. I have two questions. One which is right inner or outer as the default? Second how do I do the other one i.e. inner or outer? The key words on inner and outer do not work.
var nprs = (from n in db.FMCSA_NPR
join u in db.FMCSA_USER on n.CREATED_BY equals u.ID
join t in db.LKUP_NPR_TYPE on n.NPR_TYPE_ID equals t.ID
join s in db.LKUP_AUDIT_STATUS on n.NPR_STATUS_ID equals s.ID
where n.ROLE_ID == pRoleId
&& n.OWNER_ID == pOwnerId
&& n.NPR_STATUS_ID == pNPRStatusId
&& n.ACTIVE == pActive
select n).ToList();
if (nprs.Count() == 0)
return null;
