title: LINQ to SQL where clause returning zero
body: <p>When I run this query </p>
  
  <pre><code>var query = from a in db.commentsTable 
              select a;
  </code></pre>
  
  <p>it returns the correct amount of results but when I run this query </p>
  
  <pre><code>var query = from a in db.commentsTable 
              where a.UserId == userId 
              select a;
  </code></pre>
  
  <p>it returns 0, even though it should return 33. This is the only query that is not working. I do the same with another list and it works fine. Is the where clause causing problems?</p>
