    <p>Try breaking down the one statement into two. This would work as it cannot move the where to a place that doesn't exist yet. This does make multiple round trips to the database, but it is better than having most of several large tables being joined then culled. I would try this:</p> <pre><code>var inMemoryTable = ( from x in adc.JobManagement join j in adc.Job on x.JobId equals j.JobId join js in adc.JobStatus on j.StatusId equals js.JobStatusId join cm in adc.ClientManagement on j.ClientId equals cm.ClientId join o in adc.User on cm.UserId equals o.UserId join jm in adc.JobManagement on j.JobId equals jm.JobId where (x.UserId == aid || cm.UserId == aid) &amp;&amp; (j.StatusDate == null || j.StatusDate &gt;= getFromDate()) &amp;&amp; (jm.ManagementRoleCode == MR_MANAGER) select new { j.JobId, Job = j.InternalName == null ? j.ExternalName : j.InternalName, JobStatusDate = j.StatusDate, JobStatus = js.Code, Owner = o.Username, Role = jm.ManagementRoleCode }); var rc = ( from dv in ( from dv_j in inMemoryTable join s in adc.Submission on dv_j.JobId equals s.JobId into dv_s from s in dv_s.DefaultIfEmpty() select new { dv_j.JobId, dv_j.Job, dv_j.JobStatusDate, dv_j.JobStatus, dv_j.Owner, dv_j.Role, s.SubmissionId, s.CandidateId, s.SubmissionDate, StatusDate = s.StatusDate, StatusId = s.StatusId }) join c in adc.Candidate on dv.CandidateId equals c.CandidateId into dv_c join ss in adc.SubmissionStatus on dv.StatusId equals ss.SubmissionStatusId into dv_ss from c in dv_c.DefaultIfEmpty() from ss in dv_ss.DefaultIfEmpty() orderby dv.StatusId == null ? dv.StatusDate : dv.JobStatusDate descending, dv.Job, c.LastName, c.NickName, c.FirstName select new Projects { Id = dv.JobId, Project = dv.Job, Submitted = dv.SubmissionDate, Candidate = FormatIndividual(c.LastName, c.FirstName, c.NickName), Status = dv.StatusId == null ? ss.Code : dv.JobStatus, StatusDate = dv.StatusId == null ? dv.StatusDate : dv.JobStatusDate, Role = dv.Role, Owner = dv.Owner }); </code></pre>

    1. COyeah, i thought i'd have to do that. i was hoping that wasn't the only answer. linq already makes too many calls to the database, so one more can't hurt, :). thanks!

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
