title: Selecting rownum/max(rownum) with jOOQ
body: <p>I'm looking at a SQL query that uses Oracle's <code>rownum</code> pseudocolumn to select the row number as a fraction of the total rows:</p>
  
  <pre><code>ROWNUM/(MAX(ROWNUM) OVER())
  </code></pre>
  
  <p>I'm trying to accomplish the same thing with a query written via jOOQ. Is that possible?</p>
