The documentation for DBI and DBD::mysql will contain the information you want, and better examples. Better still for how-to's and examples is the book "Programming the Perl DBI". Don't forget to 'use strict; use warnings;' in your script(s) and declare variables in the smallest scope necessary.

A variable that is only used once often indicates of a bug, hence the warning. In the case of the example that you came across, it is probably just poor programming.
