小编use*_*670的帖子

我无法在PHP中显示特定记录.这是我的代码:

<?php

session_start();
$name = $_SESSION['MM_Username'];
mysql_connect("localhost","abc","sar");
mysql_select_db("abc");
$query = mysql_query("select * from employee WHERE username = '$name'");

while($row = mysql_fetch_row($query));
{ 
  echo $row['employee_id'];
}   

?>

这不会显示任何内容.我究竟做错了什么？
