body: <p><strong>In which function/class is the dbprefix added to the table name in Codeigniter Active Record requests?</strong></p>
  
  <p>I need to dynamically change the prefix based on the table name but cannot find the function which prepends the prefix in the first place.</p>
  
  <p>DB_active_rec.php has a dbprefix() function but this appears to have no effect.</p>
