title: sql select last n rows, sort them reversed
body: <p>From an ordered (by <code>datetime</code>) table, I need to get last 9 rows.</p>
  
  <p>Since I use...</p>
  
  <pre><code>SELECT fecha_hora
    , estado_viejo
  FROM cambios_de_estado 
  WHERE usuario_id = '35512'
  ORDER BY fecha_hora DESC
  LIMIT 9
  </code></pre>
  
  <p>...the output is inverted.</p>
  
  <p>I need to get the original order.</p>
  
  <p>The query is longer. This is the tricky part for me.</p>
