Rather than trying to scavenge around for the Mysql module, which doesn't seem to be on cpan any longer, it would be better to use the DBI (Database independent interface for Perl) module along with DBD::mysql MySQL driver for the Perl5 Database Interface module.

The DBI module is the De facto standard perl module for DB interaction. Even mysql/oracle recommends using those modules. http://dev.mysql.com/downloads/dbi.html

EDIT:

I did find the Msql/Mysql module on cpan but it hasn't been updated since 2001 and its documentation states the following.

OBSOLETE SOFTWARE

As of Msql-Mysql-modules 1.19_10 M(y)sqlPerl is no longer a separate module. Instead it is emulated using the DBI drivers. You are strongly encouraged to implement new code with DBI directly. See "COMPATIBILITY NOTES" below.

DESCRIPTION ^

This package is designed as close as possible to its C API counterpart. The manual that comes with mSQL or MySQL describes most things you need. Due to popular demand it was decided though, that this interface does not use StudlyCaps (see below).

As of March 1998, the Msql and Mysql modules are obsoleted by the DBI drivers DBD::mSQL and DBD::mysql, respectively. You are strongly encouraged to implement new code with the DBI drivers. In fact, Msql and Mysql are currently implemented as emulations on top of the DBI drivers.
