title: Check if a string contains numbers
body: <p>How do I check if a string in a MySQL field contains a number then delete them?</p>
  
  <p><strong>Example table:</strong></p>
  
  <pre><code>tbl_tags
   -------------
  | id | tag    |
   -------------
  | 1  | hello  |
  | 2  | hello2 |
  | 3  | 2hello |
  | 4  | hel3lo |
   -------------
  </code></pre>
  
  <p>The only way I can think of is to do each number individually and use <strong>LIKE '%1%' OR LIKE '%2%'</strong> etc. But there must be an easier way?</p>
