Re^2: Mysql and Perl Module

The ideal situation for that scenario is that your module takes some sort of config file with the DSN for the databse connection so that you can ship it with a tailor-made config file for each of your customers.
Look at something like Config::General to handle such a config.
Alternatively, you could make the DSN an argument that needs to be supplied by the user when running this script.
If you have a lot of stuff to do with that database then it would also be worth exploring something like DBIx::Class to handle your database in a much more abstract way.
