mysql错误，急！
Warning: mysql_fetch_assoc() expects parameter 1 to be resource, boolean given in D:\wamp1\www\empmanage\empMain.php on line 37
   
大致代码如下
  $sql="select * from emp limit".($pageNow-1)*$pageSize.",$pageSize";
  $res2=mysql_query($sql,$conn);
37行 while($row=mysql_fetch_assoc($res2)){
echo "

{$row['id']} {$row['name']} {$row['grade']}".
"{$row['email']} {$row['salary']}".
"删除用户 修改用户 ";
}
echo "";
解释下这句话是什么原因。

------解决方案--------------------
意思是36返回的不是resource而是boolen的false
36行改成 $res2=mysql_query($sql,$conn) or die(mysql_error());
看输出什么？
