I'm sure www.oreilly.com has a number of MySQL-related books, at least one of which should be at the level you're looking for, but I don't have any specific recommendations. (I learned most of the introductory DB stuff while working with Oracle and Informix, and so never really had a reason to look for any introductory MySQL books.)
I might recommend the two general database tutorials at http://www.geekgirls.com/menu_databases.htm to get a good grounding in basic and intermediate concepts, at which point the on-line manual should be less daunting.

I remember that website. I didn't like it too much at the time because i wasn't able to understand it. But now that i know some things, and have a server to practice with, i think i will give it another shot. Thank you.
