Connection Failed because: Access denied for user 'ODBC'@'localhost' (using password: NO)

$dbh=mysql_connect ('localhost','newuser','mypass');

PHP Code:

---

$dbh=mysql_connect ('localhost','newuser','mypass');
mysql_select_db ("twmweb");

$result=mysql_query("select * from inventory");
$EOF=mysql_num_rows($result);

@pino: you are correct.

You need to change the line that pino said. and you error message is saying that you are using the username "ODBC" and you are not using a password.

You're getting the error message because of the extra semicolon. You're calling mysql_error even when the connection succeeds, which means it spits out the last error message generated.
