connect to MySQL from Perl using DBI

Hi,
I want to connect perl with the mysql to select and so on but the connection don't work

code
PHP Code:
#!/usr/bin/perl 
BEGIN {
# PERL MODULES WE WILL BE USING
use DBI;
$dbh DBI->connect('DBI:mysql:C:\Program Files\MySQL\MySQL Server 5.0\data\db1','','pass') or die $DBI::errstr;}
 
# (insert query examples here...)
$sth $dbh->prepare('SELECT gene_name FROM protein_names );
$sth->execute();
$result = $sth->fetchrow_hashref();
print "Value returned: $result->{description}\n";
end{
$dbh->disconnect();

I want from this code to get all gene_name in the table and put them in a hash table.

Note:

PHP Code:
$dbh DBI->connect('DBI:mysql:C:\Program Files\MySQL\MySQL Server 5.0\data\db1','','pass') or die $DBI::errstr
here i defined the path to the db file and pass is the password i set to the mysql when i treat with and i didn't use a user name for this database

Thanks in advance

NAME
mysql_setpermission - interactively set permissions in grant tables SYNOPSIS
mysql_setpermission [options] DESCRIPTION
mysql_setpermission is a Perl script that was originally written and contributed by Luuk de Boer. It interactively sets permissions in the MySQL grant tables. mysql_setpermission is written in Perl and requires that the DBI and DBD::mysql Perl modules be installed (see Section 2.13, "Perl Installation Notes"). Invoke mysql_setpermission like this: shell> mysql_setpermission [options] options should be either --help to display the help message, or options that indicate how to connect to the MySQL server. The account used when you connect determines which permissions you have when attempting to modify existing permissions in the grant tables. mysql_setpermissions also reads options from the [client] and [perl] groups in the .my.cnf file in your home directory, if the file exists. mysql_setpermission supports the following options: o --help Display a help message and exit. o --host=host_name Connect to the MySQL server on the given host. o --password=password The password to use when connecting to the server. Note that the password value is not optional for this option, unlike for other MySQL programs. Specifying a password on the command line should be considered insecure. See Section 6.1.2.1, "End-User Guidelines for Password Security". You can use an option file to avoid giving the password on the command line. o --port=port_num The TCP/IP port number to use for the connection. o --socket=path For connections to localhost, the Unix socket file to use. o --user=user_name The MySQL user name to use when connecting to the server.
