if someone gives you a math problem, and you are required to solve it, how do you go about it?

Look up tutorials, do steps by steps.

extract data using whatever language

Probably the fastest way is to make a copy of the DB and then use DELETE * FROM xxx WHERE xxx = xxx and you get only the extraction as a result (by deleting all the rest that you dont need)

Or if you're MYSQL illiterate just import the db into phpmyadmin or something and get the data from there.

Or if you're not just generally illiterate you could bother to read the thread before you mash the reply button.
