title: Passing parameter via url to sql server reporting service
body: <p>I'm trying to pass a parameter via the url to SSRS and it appears not to work!</p>
  
  <p>I'm trying to pass a userId (string) via the url which will be passed to the database and used by the query.</p>
  
  <p>base url:
  <a href="http://blah/Reports/Pages/Report.aspx?ItemPath=MyReport" rel="noreferrer">http://blah/Reports/Pages/Report.aspx?ItemPath=MyReport</a></p>
  
  <p>tried this but it doesn't work:
  <a href="http://blah/Reports/Pages/Report.aspx?ItemPath=MyReport&amp;UserId=fred" rel="noreferrer">http://blah/Reports/Pages/Report.aspx?ItemPath=MyReport&amp;UserId=fred</a></p>
  
  <p>Any ideas</p>
