lakukan ini

<select name='status' id='status'>
        <option value=''>--Select--</option>
        <option value='0'>Approve</option>
        <option value='1'>Reject</option>
        <option value='2'>Pending</option>
</select>
<div id="autosavenotify"></div>

<script>
$(document).ready(function(){
$('select').live('change',function () {
        var statusVal = $(this).val();
        alert(statusVal);
        $.ajax({
                 type: "POST",
                 url: "saveStatus.php",
                 data: {statusType : statusVal },
                 success: function(msg) {
                     $('#autosavenotify').text(msg);
                 }
      })
  });
});
</script>

di saveStatus.php lakukan pembaruan mysql Anda

<?php

 $st=$_POST['statusType'];
 $qry =" UPDATE tableName SET `tablefield`=$st .. ";
 $done = mysql_query($qry);
 if($done)
 {
   echo "Saved Successfully";
 }
?>
