This is a perfect example of how to use Perl DBI:

http://www.cyberciti.biz/faq/how-to-...se-using-perl/

How I go about doing it is I load a plugin that parses the XML config of the server.

Put it in plugins folder:

Mysql.pl
Code:
sub LoadMysql{	
	use DBI;
	use DBD::mysql;
	# CONFIG VARIABLES
	my $confile = "eqemu_config.xml"; #default
	open(F, "<$confile") or die "Unable to open config: $confile\n";
	my $indb = 0;

	while(<F>) {
		s/\r//g;
		if(/<database>/i) {
			$indb = 1;
		}
		next unless($indb == 1);
		if(/<\/database>/i) {
			$indb = 0;
			last;
		}
		if(/<host>(.*)<\/host>/i) {
			$host = $1;
		} elsif(/<username>(.*)<\/username>/i) {
			$user = $1;
		} elsif(/<password>(.*)<\/password>/i) {
			$pass = $1;
		} elsif(/<db>(.*)<\/db>/i) {
			$db = $1;
		}
	}
	# DATA SOURCE NAME
	$dsn = "dbi:mysql:$db:localhost:3306";
	# PERL DBI CONNECT
	$connect = DBI->connect($dsn, $user, $pass);
}
Example snippet:

Code:
### Read from DB
	if(!$connect){ $connect = plugin::LoadMysql(); }
	$query = "SELECT
		cust_npc_scaling.level,
		cust_npc_scaling.type,
		cust_npc_scaling.hp,
		cust_npc_scaling.mana,
		cust_npc_scaling.mindmg,
		cust_npc_scaling.maxdmg,
		cust_npc_scaling.attack_speed,
		cust_npc_scaling.AC,
		cust_npc_scaling.STR,
		cust_npc_scaling.STA,
		cust_npc_scaling.DEX,
		cust_npc_scaling.AGI,
		cust_npc_scaling._INT,
		cust_npc_scaling.WIS,
		cust_npc_scaling.CHA,
		cust_npc_scaling.MR,
		cust_npc_scaling.CR,
		cust_npc_scaling.DR,
		cust_npc_scaling.FR,
		cust_npc_scaling.PR,
		cust_npc_scaling.hp_regen,
		cust_npc_scaling.npcspecialattks,
		cust_npc_scaling.spellscale,
		cust_npc_scaling.healscale
		FROM
		cust_npc_scaling
		ORDER BY cust_npc_scaling.level, cust_npc_scaling.type";
		$query_handle = $connect->prepare($query);
		$query_handle->execute();
		$NTYPE = 0; my @SD;
		while (@row = $query_handle->fetchrow_array()){ $SD[$row[0]][$row[1]] = [@row]; }
That should help alot

Thanks,
