A very readable, useful book to introduce you to SQL. A local community college uses this book as their textbook in their SQL class. I recommend this to all of my friends looking to learn/use SQL.
This is my fourth purchase of the disappearing book. It's not one of those books that you can lend to someone and ever expect to see it back. Last week I collared a fellow programmer who had obviously pilfered my last copy. He had the gall to say he didn't want to part with it after I caught him even though our offices are right next to each other¿s. It's not only the clearest book that I've ever seen on the subject, unlike most books, it's useful as a reference when you¿re finished reading it. I don¿t know what it is about this book that makes you remember the examples and reach for it whenever you need to refresh your memory on how to do something. It¿s the type of book that you must read carefully because every sentence includes a key concept. If you're one of those people that likes to highlight key concepts, forget about it with this book. You'll just be changing the color of the pages. If you think something has been repeated, read it again because you¿ve no doubt missed an important concept. If I could only have one book about SQL databases, I can say unequivocally that this would be my choice. That was true when I first got into SQL databases several years ago, and it¿s still true today. Today when I train others, the first thing that I tell them is to get a copy of this book, read it from cover to cover and do the examples. The only problem people seem to have with this book is laying it down once they get started into it. There have only been about five books in my entire life that I can say that about. Seldom do people have questions when they are finished.
