Say you have a list of IDs: <pre><code>string str = "82174F2000000, 82174F2000001, 82174F2000002, 82174F2000003, 82174F2000004, 82174F2000005"; </code></pre> And you do this: <pre><code>var tids = new List<string>(str.Replace(", ", ",").Split(',')); var tntable = tids.AsQueryable(); </code></pre> And you want to compare it to a table with a Left Join: <pre><code>var line = from c in db.Ctable join l in tntable on c.CarID equals l.CarID into c_j from l in c_j.DefaultIfEmpty() select new { Name = c.OwnerName, Hours = c.Hours }; </code></pre> looks like the tntable doesn't have a field called 'CarID'. Can someone please help? This is for LINQ to Entity. I have seen this: <a href="https://stackoverflow.com/questions/3922619/how-to-compare-liststring-to-db-table-using-linq">How to compare List<String> to DB Table using LINQ</a> But don't know to do a LEFT JOIN. TIA! I know this is long; but thanks for reading. UPDATED FOR MichaC: In the database in CTable we have these CarIDs: <pre><code>CarID _____ 82174F2000000 82174F2000001 82174F2000002 82174F2000003 </code></pre> Let's just say the table (tntable) contains the string broken down into records: <pre><code>CarID _____ 82174F2000000 82174F2000001 82174F2000002 82174F2000003 82174F2000004 82174F2000005 </code></pre> So, a LEFT JOIN like this: <pre><code>SELECT C.CarID, T.CarID FROM CTable C LEFT JOIN tntable T ON C.CarID = T.CarID </code></pre> Will yield you this: <pre><code>T.CarID C.CarID _______ _______ 82174F2000000 82174F2000000 82174F2000001 82174F2000001 82174F2000002 82174F2000002 82174F2000003 82174F2000003 82174F2000004 NULL 82174F2000005 NULL </code></pre>

Guidance

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.
