Query: Waste of money..

If you are of the type who would like to look at an oracle query example, run it against a database and watch the results - do yourself a favor. Stay away from this book.But if you like reading oracle queries like a fiction novel - by all means get this book. The book talks about a parts distributor database the scripts for which Mr. DB Administrator Sanjay Mishra has decided to lock in his closet.I am fuming with anger at the uselessness of this book. This book has good content which goes down the drain because of the ZERO PRACTICAL test. I am giving it a rating 2 coz the content covers what it intents to cover - basics of SQL. Barring that fact, this book is worth only a rating of .5
