title: SQLDependency Fails when SQL query compares Datetime
body: <p>I'm working on a monitoring program for our shipping department that will show orders that are ready to ship.  I've been working with SQLDependency to do this and finally got it functioning, however, when I try to add some more specifics to my query, specifically comparing to a datetime column, the OnChange event is repeatedly triggered.  When I remove the comparison, it works perfectly.</p>
  
  <p>I've been through <a href="http://msdn.microsoft.com/en-us/library/ms181122%28v=sql.105%29.aspx" rel="nofollow">Microsoft's documentation</a>, but I don't see anything saying this type of comparison isn't valid.</p>
  
  <p>I've simplified my query down to:</p>
  
  <pre><code>SELECT [SALESLINE].[SHIPPINGDATEREQUESTED]
  FROM [dbo].[SALESLINE]
  WHERE [SALESLINE].[SHIPPINGDATEREQUESTED] &gt;= '20130614'
  </code></pre>
  
  <p>Does anyone know what I might be doing wrong or another way to compare against a date?</p>
  
  <p>I can post some of my code, but, as I said, it is working if I don't have a datetime in my WHERE clause.</p>
