title: mysql SELECT WHERE string contains characters
body: <p><br/>
  I have a table field <code>events</code> which can contains:</p>
  
  <ul>
  <li>Only a sequence of number, for example: <code>45</code></li>
  <li>or a sequence of number divided by the symbol <code>|</code>, for example <code>55|65|76</code></li>
  </ul>
  
  <p>I think i have to use <code>LIKE</code>, but i don't know how. Can you help me?</p>
  
  <p>Thanks</p>
