When I started to learn data base in autumn semester, I contemplate to read off the book in which case I am supposed to finish it. But I gave up quickly, I just think it is enough to pass the exam and read some of the chapters which is basiclly enough for me... Everything went wrong when my negative mind.
A pretty good reference when learning SQL. The book starts off with introductory information on database systems and the design concerns regarding relational databases. Then it starts going into SQL statements and how to use a database better. The flow of the chapters makes for an easy read.
