need a good book to learn sql

[Connoisseur]

hey guys. i'm in a job which is very database intensive and im gonna be mainly using programs like sql and attenix. I took dbms like a year and a half ago and forgot most of it. I was wondering whether anyone could suggest a good book or two that not only gives a good tutorial but also introduces advanced functions and commands. thx in advance.
