title: Tableau rawsqlagg_real
body: <p>Could somebody please give me a little guidance on rawsqlagg_real function in Tableau. What is right syntax for it when it is used to get data from MySQL. 
  I used it as per my understanding but I am getting an error "No such column [__measure__3]".</p>
  
  <p>Code:</p>
  
  <pre><code> RAWSQLAGG_REAL("select count(Film Id) from flavia.TableforThe_top_10percent_of_the_user where count(distinct(User Id)) = %1",[it sucks])
  </code></pre>
