title: One INSERT with UNIONS or multiple INSERTS?
body: <p>I have a sql function that returns a table. The table is populated via 6 or so reasonably complex statements.</p>
  
  <p>Is it better to UNION together these statement so there is only 1 insert or are these better kept separate?</p>
  
  <p>Or does it make no difference whatsoever?</p>
