title: Error while connecting to stored procedure in Tableau
body: <p>I'm getting this error while trying to connect to a stored procedure as data source:</p>
  <blockquote>
  <p>Unable to complete action<br />
  The stored procedure returned no results. The fields don't have column names, or the data in the fields is not a supported data type</p>
  </blockquote>
  <p>But the same stored procedure returns data in database. Any idea on this?</p>
