title: SQL, varchar field with decimals entries = ORDER BY not sorting proprely
body: <p>So i have a table with a VARCHAR field. It is used to sort a lot of decimals value:</p>
  
  <p>Let's say i have the following entries in my VARCHAR field:</p>
  
  <ul>
  <li>9.99 </li>
  <li>263.28</li>
  <li>9.98</li>
  </ul>
  
  <p>Let's say I want to display all entries using ORDER BY varchar DESC. The result would be:</p>
  
  <ul>
  <li>9.99</li>
  <li>9.98</li>
  <li>263.28</li>
  </ul>
  
  <p>When obviously <code>263.28</code> should be the first one. What's wrong ?</p>
