Its got a live SQL prompt so you can practice with their database 
and see the results. It seems fairly clearly written too.

Caveat: I'#ve only gone through a few of the pages to check 
it out, I haven't followeed it to completion - and I already 
know SQL which always helps!

But its best to get a book that focuses on the specific dialect 
used by your database in the longer term.
