title: Warning: #1265 Data truncated for column 'pdd' at row 1
body: <p>I am having trouble trying to set the <code>PDD</code>(patient death date) to null on PHPMYADMIN until such death date comes;  also on the client end then I can check for <code>NULL</code> data to use it.</p>
  <p>Could anyone suggest me a solution, please ?</p>
  <pre><code>patientnhs_no   hospital_no sex     name    surname     dob     address     pls  pdd

  </code></pre>
  <p>(PDD should be null if is alive or death date if died)</p>
