title: MySQL ORDER BY x-y/x ASC
body: <p>I want to order ascending a MySQL query by this rule: <code>x-y/x</code></p>
  
  <p>x = price</p>
  
  <p>y = price2</p>
  
  <p>price and price2 are the columns from the MySQL table.</p>
  
  <p>I have this query but unfortunately doesn`t work.</p>
  
  <pre><code>SELECT * 
  FROM albums 
  WHERE price2 &gt; 1 
  ORDER BY price - price2 / price ASC
  </code></pre>
  
  <p>Thanks for attention.</p>
