    <p>I'm trying to convert this rather complex (from my perspective as I don't deal with SQL) query into LINQ:</p> <pre><code>SELECT f.description, s.description, file_no,taskid, h.description from_userid, userid, h.starttime, locktime, lockby, h.status, h.endtime FROM history h INNER JOIN flowdefinition f on h.flowid = f.flowid INNER JOIN stepdefinition s on h.flowid = s.flowid and h.stepid = s.stepid WHERE taskid = 'SERVER2012_03_08_09_31_40_367' AND h.status in ('R','U','C','K') AND h.flowid not in (999) order by endtime </code></pre> <p>And this is what I have so far:</p> <pre><code>var resultList = from h in context.History_master join f in context.flowdefinition_master on new { h.flowid, h.LocId } equals new { f.flowid, f.LocId } into hf from h in hf.DefaultIfEmpty() join s in context.stepdefinition_master on new { h.stepid, h.LocId } equals new { s.stepid, s.LocId } into hs from s in hs.DefaultIfEmpty() where h.file_no == fileNumber orderby h.endtime select new { }; </code></pre> <p>But this complains that "The range variable 'h' conflicts with a previous declaration of 'h'. I understand that it says it is like a second declaration, but I don't know how else i would do this in LINQ. Any help with this (complete or partial :) ) would be greatly appreciated!</p> <p>//EDIT:</p> <p>If i change the <code>from h in hf.DefaultIfEmpty()</code> to <code>from h1 in hf.DefaultIfEmpty()</code> as suggested, the h1 does not have the same properties as h. So i can't do the second join because the tables are not there...</p>

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.
