title: Querying last 5 years
body: <p>I want to query all products sold in the last 5 years.<br/>
  It is possible to do it like this:</p>
  
  <pre><code>select * from products
  where time between sysdate-1826 and sysdate
  </code></pre>
  
  <p>But it there also a nicer way instead of calculating all the days and subtract it from <code>sysdate</code>?</p>
