Suggestions for a complete beginner

I've dabbled in some programming so I'm not a total newb, but I'm beginning a project using HeidiSQL and I have no experience with SQL or databases in general. Can any of you offer some suggestions for good books or websites or anything else that can help me learn starting with the very basics of SQL?

Thanks!

To clarify. Databases are there so you are able to not worry about big data storage. It worrys about it instead of you. All you need is to make connection to db with your prog and use simple command language (SQL) to set/get data from/to db. SQL is simple string command thta db understands.
