title: Eclipse BIRT input parameter in FROM clause
body: <p>I'm using eclipse birt to make my reports.
  My goal is to take input parameter, to chose different table used to my dataset. I know that i can use something like this:</p>
  
  <p><code>id = ?</code></p>
  
  <p>In my <code>WHERE</code> clause. But i would like to accomplish something like that:</p>
  
  <p><code>FROM CONCAT('tablexyz',?)</code></p>
  
  <p>So i can do my report for tables <code>tablexyz17</code>, <code>tablexyz18</code>, <code>tablexyz19</code>, etc. I have tried to do something like this:</p>
  
  <pre><code>SELECT * FROM CONCAT('tablexyz',year)
  WHERE year = ?
  </code></pre>
  
  <p>But it gave me an error.
  Any ideas how can i accomplish this?</p>
