title: update table column with different random numbers
body: <p>I have this query</p>
  
  <pre><code>UPDATE f1
  SET col = (SELECT ABS(300 + RANDOM() % 3600))
  </code></pre>
  
  <p>that update the "col" column with a random number between 300 and 3600.
  But it returns the same random number for all the rows. Is there a way to update the rows with different random numbers?</p>
