php 数据写入mysql问题

*****连接数据库*******
数据库连接成功！！

Warning: mysql_query() [function.mysql-query]: Access denied for user 'ODBC'@'localhost' (using password: NO) in D:\PHPnow-1.5.6.1428396605\htdocs\zhangxiaojiao\register_1.php on line 19

Warning: mysql_query() [function.mysql-query]: A link to the server could not be established in D:\PHPnow-1.5.6.1428396605\htdocs\zhangxiaojiao\register_1.php on line 19

数据库都显示连接成功了，这是什么问题？
错误代码
$sql="insert into userinfo values('$name','$password1','$photourl')";

$result=mysql_query($sql);
