title: Fetch rows where first character is not alphanumeric
body: <p>I am adding a few new features to a small project i'm working on and one of them is alpha pagination which looks like</p>
  
  <blockquote>
    <p># 0-9 A B C D E ... X Y Z</p>
  </blockquote>
  
  <p>I can easily fetch items by their first letter using something like</p>
  
  <pre><code>SELECT * FROM ... WHERE name LIKE 'A%' ...
  </code></pre>
  
  <p>Grouping everything that starts with a number and all other characters is a little more difficult, I assume it would have to use MySQLs REGEXP.</p>
  
  <p>Just to be clear, I need help creating two queries which will fetch all rows where</p>
  
  <ul>
  <li>the first character of a column is numeric</li>
  <li>the first character of a column is not alphanumeric</li>
  </ul>
