db connect

Posted 03 April 2008 - 01:15 PM

I need to connect to a mysql database in subroutines in different files (all located in the same directory). Instead of having the connection paramaters hard coded in each subroutine, is there a way to set the parameters in one file, call it something like dbconnect.pl, save it separately, and then include that file every time I need to connect to the database in my other files?

You can do something similar in PHP using the 'include' command, something like:

//connect to mysql server & database
include 'dbconnect.php';

$sql="INSERT INTO user (FirstName, LastName, Age)
VALUES.....etc etc...

Ive tried using perls 'require' command, but im not yet familiar or comfortable with changing the @INC path (nor am I with creating .pm perl modules) which appears to be what I need to change to get perl to look for my dbconnect.pm if I create it.

Thinking there must be a standard way of connecting to a db where you only have to change the parameters once without having to go through your whole site.

Is This A Good Question/Topic? 0

Yes, there is. Here's how I usually do it:
package config;

use Exporter;
our @ISA = qw(Exporter);

our %config;
our @EXPORT = qw(%config);

%config = (
	dbName	=>	'bat',
	dbUser	=>	'foo',
	dbPass	=>	'bar',


And here's the code inside a script that uses it:
#!/usr/bin/perl -w

use strict;
use DBI;

use config;
my $dbh;
$dbh = DBI->connect(
	{RaiseError => 1},
