Scripts to query database

If anyone could help, your expertise would be greatly appreciated.
I want to extract a list of all the email addresses of the students attending Duke. I'm starting a club on campus and want to email them about our inaugural event. Technically, I think there is a way to query their public domain for the database containing these tables. The url is http://www.duke.edu/cgi-bin/phcgi.pl, but i need advice, code, and/or direction on how to extract, query, download the table field with student email addresses. I tried the register's office and dean of students, but haven't gotten a response. Our event is next week and any assistance will indite my eternal gratitude.

u need to find out what db it is (name etc), username and password to connect and a port number. it'd be good to also get the table and field names (but not essential).

then just use a client for that db to get the info u require. or write a simple program that connects to the db and pulls out the info.
