Why buy this book? Like many people, I also ask this question before spending my hard-earned bucks. In the existence of free web material and many well-written comprehensive books, this question gets more weight. SQL is older than most of us, so I can’t claim to be conveying some extraordinary stuff through this book. What makes this title unique is its slender size. If you are looking for a real compact practical guide on SQL, then this book is for you. For beginners, I have tried to confine an ocean to a bucket in order to equip them with SQL knowledge in the shortest time possible. SQL language is too voluminous and exposure of every aspect of this huge language is a very tedious task.
