custom mysql with wordpress mysql

[monkeytooth]

I use a custom class I got some time back that I use in about 99% of my php/mysql work as most of my work is custom jobs. However just recently I snagged a client whom wants my normal coding work but wants to incorperate their wordpress blog into some of the element I am making. Which, getting that to work no problem. However I am now running into conflict with my mysql class vs the class wordpress seems to have built in, when I tie in Wordpress my class goes haywire and fails. So I guess I am trying to find out if its possible to use customized sql and wordpress sql side by side or do I have to figure out the WP sql class and use it for my needs instead. Mind you most of the work required by my end isn't using the WP tables its using custom tables. So that in mind.. anyone got either a link or file location to the mysql class WP has so I can try to learn it and then use it for my custom work in this case, or does someone know of a way to use my class with the wp class in unison. The class I use came from

http://www.ricocheting.com/code/php/mysql-database-class-wrapper and I have been using it for some time, ive grown used to using it. So I dunno, any help would be helpful
