SQL is full of difficulties and traps for the unwary. You can avoid them if you understand relational theory, but only if you know how to put that theory into practice. In this book, Chris Date explains relational theory in depth, and demonstrates through numerous examples and exercises how you can apply it to your use of SQL.
This third edition has been revised, extended, and improved throughout. Topics whose treatment has been expanded include data types and domains, table comparisons, image relations, aggregate operators and summarization, view updating, and subqueries. A special feature of this edition is a new appendix on NoSQL and relational theory.
- Could you write an SQL query to find employees who have worked at least once in every programming department in the company? And be sure it’s correct?
- Why is proper column naming so important?
- Nulls in the database cause wrong answers. Why? What you can do about it?
- How can image relations help you formulate complex SQL queries?
- SQL supports "quantified comparisons," but they’re better avoided. Why? And how?
Database theory and practice have evolved considerably since Codd first defined the relational model, back in 1969. This book draws on decades of experience to present the most up to date treatment of the material available anywhere. Anyone with a modest to advanced background in SQL can benefit from the insights it contains. The book is product independent.

About Us: Coas Books is New Mexico’s largest second-hand bookstore with more than 500,000 books in stock! We have an incredible selection of new and used books — including regional and out-of-print books —, CDs, DVDs, Vinyl, VHS, audio books, and games. Coas Books is family owned and operated, with two stores located in Las Cruces, New Mexico. We receive hundreds of books every day, so our inventory is constantly changing and full of hidden gems! Our History: Coas Books was founded in 1983 by archaeologist Pat Beckett. It started out as an archaeological publishing company specializing in anthropology books. As Pat's vast collection of books continued to grow, he purchased a local paperback exchange, and with that Coas Books was born. The name Coas has its roots in archaeology, coming from the Nahuatl term “coa” — meaning digging stick —, and the acronym for "Center of Anthropological Studies". Today, Coas Books is run and operated by Mike and Veronica Beckett as they continue to proudly serve the community in the heart of Las Cruces.…
