Script for parsing IRC-Channel permanently and pushing information to MySQL

Ladies and Gentlemen, I hope I am right with this request here. I am in need of a script (maybe for an eggdrop in IRC - I dont know so much about it) which is permanently connected to a defined IRC-Channel and is parsing the entries of a specific user inside this channel. It then should write the gathered information in a mysql-db table. So, as soon as there is posted a new chatline by this specific user, it should parse it, and then push it to the db. I dont know what need for make this running, so please offer and lets discuss first.
