title: Tableau: How to add parameters in Initial SQL
body: <p>I've been stuck with the below and been searching for an answer. Also opened a ticket with Tableau support team and waiting for them to get back.</p>
  
  <p>My Question:</p>
  
  <p>I have some volatile tables that I created in Teradata.</p>
  
  <p>In Tableau with the Live connection I placed the volatile tables in Initial SQL and in my custom SQL i'm just doing a Select * from that Volatile table which works completely fine.</p>
  
  <p>Now, I have to declare a parameter in the initial SQL (This is where a user enters some value on the dashboard in the parameter field and gets the data).</p>
  
  <p>Can this be accomplished? Appreciate your responses.</p>
