mysql_fetch_row(): supplied argument is not a valid MySQL result resource，何人能解？该如何解决

mysql_fetch_row(): supplied argument is not a valid MySQL result resource，何人能解？
代码如下：

/*
 * Created on 2012-1-1
 *
 * To change the template for this generated file go to
 * Window - Preferences - PHPeclipse - PHP - Code Templates
 */
 $conn = mysql_connect("localhost","root","") or die ("连接出错");
 mysql_select_db("dongxinb",$conn);

 $sql="SELECT * FROM 'word'";
 $query=mysql_query($sql,$conn);
 $row=mysql_fetch_array($query);
 echo $row[name];
?>

其中name为dongxinb数据库word表的字段。
错误信息：Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in D:\wamp\www\word\1.php on line 13

其中INSERT能正常插入。




------解决方案--------------------
SQL 错了

修改成
$sql="SELECT * FROM word";
------解决方案--------------------

PHP code

<?php /*
 * Created on 2012-1-1 To change the template for this generated file go to
 * Window - Preferences - PHPeclipse - PHP - Code Templates
 */
include ("conn.php");
?>

html; } ?>

姓名:{$row['name']}
Message:{$row['words']}	更新时间:{$row['date']}
