Extensive Treatment of Nulls,
By Kenneth L Gutwillig (New York, NY United States) - See all my reviews
This review is from: SQL: Visual QuickStart Guide (Paperback)
Anyone who uses SQL regularly knows that it's absolutely critical to understand nulls - you can't write SQL programs or interpret results without mastering them. In most of the SQL books that I've read, nulls are mentioned once near the beginning and not given much screen time afterwards - perhaps popping up in an example here and there. This book takes the different (and welcome) approach of weaving the implications of nulls throughout the entire text. In addition to null rudiments, this book addresses crucial issues such as detecting and counting nulls, how nulls give rise to three-value logic (true/false/unknown), when nulls are considered to be duplicates and when they aren't, substituting actual values for nulls and vice versa, how nulls sort, how nulls propagate through computations, which functions ignore nulls and which don't, how nulls affect joins, and how nulls cause problems in subqueries. The book also contains specific tips for Oracle, which (for some reason) considers empty strings to be nulls.

This Book Makes My Job Easier.,
By Melanie Pennington (Portland, OR United States) - See all my reviews
This review is from: SQL: Visual QuickStart Guide (Paperback)
There are several "software-independent" SQL books available. I thumbed through a number before landing on this one. I believe I got real lucky. I'm a research analyst at a large medical center. I pull data from various sources using SQL front-ends and stuff data into MS Access for analysis or additional manipulation. I needed an SQL reference for both parts of my job, understanding what I was getting from the hospital systems and writing better SQL in Access or imbeddded SQL in VBA code. This book serves my needs because it is a thorough reference and also because it has plenty of Access examples and tips. I'm also impressed with the layout of the Visual QuickStart Guide. It is very easy to find the information you are after and the bullet points are generally right on target with the details important to the task at hand. I haven't had to read the entire book cover to cover to do some work, and that's the point. When the author does interject himself, his comments are insightful and meaningful. An example, "Although SELECT is powerful, it's not dangerous. You can't use it to add, change or delete data... The dangerous stuff starts in Chapter 9." A great technical reference in a crowded field.

Amazing SQL query book,
By "atl123" (Boston, MA) - See all my reviews
This review is from: SQL: Visual QuickStart Guide (Paperback)
I would recommend this SQL book for acadamic classes to use it. As most of the SQL text book out the market really confuse student a lot without practical examples on how to use it. This book explains in details in a qucik and visul way. Students can also use this book as reference on how different database work with SQL. Excellent SQL book i have never seen before. Thanks for the author, Chris Fehily who did the great job on it.
