title: SubSonic 3.0.0.3 Calling Stored Procedure Issue
body: <p>I have updated the subsonic reference from 3.0.0.0 to 3.0.0.3, when I try to execute a stored procedure then I get a following error </p>
  
  <p>Implicit conversion from data type sql_variant to varchar is not allowed. Use the CONVERT function to run this query.</p>
  
  <p>I am calling the store procedure as follows</p>
  
  <pre><code>db.GetAllLoanApplications(orderBy, direction, userEmail,"","","", 
                            Convert.ToString(userId)).ExecuteReader();
  </code></pre>
  
  <p>GetAllLoanApplications is the Stored Procedure Name</p>
  
  <p>Please tell me how I will be able to fix this issue,</p>
  
  <p>Regards,<br>
