'MySQL in a Nutshell' is another solid release in the family of 'Nutshell' books by O'Reilly. As with all other Nutshell books, this isn't a learning book, moreso a shorter reference manual for experienced developers who know what they are using and need a guide to help them out through the process. With MySQL In A Nutshell you are getting exactly that. Spread over nearly 550 pages and 19 Chapters, here's an overview of the content within:

01. Introduction
02. Installing MySQL
03. MySQL Basics
04. Security, User Statements, Functions
05. Database And Table Schema Statements
06. Data Manipulation Statements And Functions
07. Table And Server Administration Statements And Functions
08. Replication Statements And Functions
09. Stored Routines Statements
10. Aggregate Clauses, Functions And Subqueries
11. String Functions
12. Date And Time Functions
13. Mathematical Functions
14. Flow Control Functions
15. MySQL Server And Client
16. Command-Line Utilities
17. C API
18. Perl API
19. PHP API

The layout is good, separation of data is intelligently laid out and the writing is solid. If you are a MySQL developer or admin that is looking for a resource by your side at all times this is a great book to have!!

***** RECOMMENDED

It's a great reference but dated. If I had known that it only covers through version 4, I would not have purchased it.

The book is "A Desktop Quick Reference" just as billed on the cover. It is explicitly MySQL-centric and doesn't stray from that core message. It is extremely up-to-date considering the rapidity of movement in MySQL development progress.

I feel that its author, Russell Dyer is the kind of person who is easy to talk to and immediately be comfortable with based on his style and presentation in this book.

The content of this book is very well organized in keeping with the finest traditions at O'Reilly & Associates. There is an installation guide, tutorial, SQL syntax reference, MySQL built-in functions section(s), command-line utilities reference and programming languages API references for PERL, PHP and C. These API references demonstrate commonplace MySQL usage through clear, easy-to-read examples that make good sense.

It is a very comprehensive text that reads as easily as a favorite novel yet is concise enough to be your first "go-to" on MySQL issues you may face day-in and day-out. It is truly the "most advanced kingfisher" (cover animal) on the topic and, like the Pied kingfisher, it is lightweight and demonstrates keenly honed survival skills.

I use MySQL daily and I find it very useful and enjoyable. I don't want to become an SQL guru or even a DBA, as a programmer, I enjoy having MySQL In A Nutshell close at hand so that I can focus on writing code. Thank you Mr. Dyer (and the folks at O'Reilly) for a job well-done! I heartily recommend it to everyone using MySQL. The convenience of this publication clearly outweighs its cost. Newcomers and RDBMS "old-timers" will appreciate this book equally.

Ah, "Nutshell" books - you gotta love `em. Or maybe you don't. I won't get into the pros and cons of online documentation versus books because this subject has been rehashed ad infinitum. Truth is, there are pros and cons for both, and we each have our own reasons for our own preferences.
That being said, if you like book documentation - and "Nutshell" books in particular - then you will like this book. I happen to think it is a good idea to tear yourself away from the keyboard/screen every once in awhile, and the "Nutshell" books give you a good reason for doing so.
I'm not a SQL expert, so I liked the tutorial-flavored introductions at the beginning of each chapter, followed by the conversational tone of the clear and concise examples. I did not have this book when I first started programming using MySQL, and that's too bad because it could have saved me a lot of wasted time with its explanations of some of the more nefarious "gotchas" of the language.
I have but one criticism and one suggestion:
Criticism: The following APIs are covered at the end of the book: Perl, PHP, and C. I can see leaving out COBOL and Lisp (if there are even APIs for these languages), but Java? Granted, the Java interface to MySQL is well-documented in many places, but if you are discussing the *major* programming language APIs to MySQL then you should do just that.
Suggestion: The beginning of the book provides an introduction to MySQL via command-line instructions. I can see doing this, even though no one interacts with databases through the command line. What I think would be even more useful would be a brief discussion of the two tools that everyone does use: MySQL Administrator and MySQL Query Browser. A couple of chapters (along with some screen shots) of what they are, why we need them, where to get them, and how to use them would really make this book perfect. (If you don't forget that Java API chapter!)

Well the book certainly seems to cover MySQL's features quite comprehensively. But, as it is a reference manual, it does not attempt to teach you MySQL or the theory of relational databases. For a given MySQL command, the book's explanation is succinct and useful. Provided you already have a background in the area. Much of the book's discussion is probably already available in equivalent form in the online help. But hardcopy is nice to have.

Going through the functions, what you might appreciate about MySQL is that many of these are generic SQL functions. If you come from any other SQL implementation, your background will be relevant to much of the book.
