SQL Clearly Explained, Second Edition (The Morgan Kaufmann Series in Data Management Systems)

This book explains SQL very clearly indeed, as the title implies. I knew a bit of SQL before I started reading this book, so the first 50-odd pages didn't teach me much, but they still made me understand a few things here and there more thoroughly. I got my copy yesterday, and I'm at around page 100 now. For a technical book, it's quite easy to go through, in my opinion, even though it's rich in quality content. The book is extremely well organised, and the chapters flow from one to the next smoothly. There are lots of examples which always clearly back up the explanations. Also, the example database in this book is consitently used, i.e. you do not have completely different examples everywhere which would only make things confusing. There are a few minor typos here and there, but even so, I still rate this book 5/5.
