title: Convert strftime in SQLite request to MySQL
body: <p>I converted the SQLite line</p>
  
  <pre><code>WHERE strftime('%d%m', orders.created_at) = .......
  </code></pre>
  
  <p>directly to a MySQL monster:</p>
  
  <pre><code>WHERE CONCAT(CAST(DAY(orders.created_at) AS CHAR), LPAD(CAST(MONTH(orders.created_at) AS CHAR), 2, '0')) = .........
  </code></pre>
  
  <p>Please, help me to rewrite it to a shorter one.</p>
