I'm currently doing some consulting work to bridge the gap between Oracle and MySQL. Being in a Windows environment, I'm using the Activestate Perl distribution. Fortunately, it includes a nice ODBC module for connecting to Oracle out of the box. The bad news is, it doesn't contain a MySQL module. Luckily, I found a third party host that does provide the module. The following ppm (Perl Package Manager) one-liner takes care of the issue.
C:\>ppm install http://cpan.uwinnipeg.ca/PPMPackages/10xx/DBD-mysql.ppd
