Having worked in java and oracle with pl/sql some time ago, I'm in the "probably better not to use stored procedures" camp for most environments - but now that mysql offers them, I figured it was best to see how they tackled the problem and this o'reilly book looked good by authors with good credentials. And, fortunately, O'Reilly didn't let me down - they've had really strong offerings recently after a bit of a bad spell and this book was no exception.

This book is well written and well organized - something too few books are these days! It focuses on incremental teaching, but sidesteps the pitfalls that many such books do by pointing out when certatin features are glossed over at this point to be further explained in a future chapter. This is the perfect way to handle that problem, but one so few books take the time to do, leaving you puzzling over whether or not you need to fully understand particular examples.

It's divided into 4 sections. For me, the heart of the book was in the first 2. The first "Stored Programming Fundamentals" gives you the nuts and bolts of the language - loops, blocks, variables, error handling, etc.. Very well written, very well organized and easy to follow.

The second part "Stored Program Construction" goes into more detail with working examples of stored procedures and functions. More language details are brought to light, it demonstrates how to use transactions in this context and triggers are introduced and explained. These two sections were great, to the point and easy to follow. The only minor qualm I had was their only incidental discussion of scoping - they'd address it with a sentence here and a note there, leaving you to glean how things worked. It's not complex, but a short paragraph dedicated to scope would have really been nice.

The third part, I think, was unnecessarily long. "Using MySQL Stored Programs in Applications" - this covered how to work in php, java, perl, python and .net. Which was great, but they put in about 150 pages, almost a quarter of the book to this task and almost all of it was dedicated to the basics of how to use databases in these languages. Very basic querying, etc. It wasn't in the scope of the book and shouldn't have been - the whole thing should have been a single chapter that just discussed how to work with stored programs in each of the languages.

The last section, "optimizing stored programs" was very good. It suffered a little bit from covering topics that shouldn't have been in the book - but they cover it very well. SQL Tuning is given a lot of pages, but they very succinctly cover many bases in a very easy to grasp manner. They discuss how to use stored programs to increase security, and they dedicate a chapter to the actual mechanics of optimizing your stored program code (aside from optimizing the sql that it might include). They conclude on an excellent Best Practices chapter that gives you the authors' insights on everything from development to style to sql practices. I really enjoy it when books include these, as it gives a lot of insight into how the authors think about programming and you can see where your thoughts coincided with and contradict - and hopefully (as was the case with this book) get you thinking a little bit more about things you might not be actively thinking about.

Overall this book is a great book. It's biggest failing, if you can call it that, was including too much. I would have liked a book maybe 2/3 the size and more tightly focussed. There are many books on sql optimization and hordes of books and online resources dedicated to using mysql with various programming languages. An excellent book that gives a pretty balanced view of the pros and cons of stored programming (although they do show a slight bias towards the use of - but what can you expect? :).

The good: I found to book to be generally useful. The approach the book takes is good. Lots of examples are provided along with a good amount of explanation.


The not-so-good: There seem to be quality or editorial issues with some of the examples. When I run them through the query browser in MySQL version 5 I have problems with some of them. For example Example 2-7 calls another procedure new_salary, which doesn't seem to exist by that name in the book or on the website. This makes it much more time consuming for a newbie to actually run and digest the examples than it should.

This book has an excellent coverage of the MySQL 5.0 stored routines (stored procedures, stored functions and triggers).
But it also provides with invaluable hints and guidelines for general MySQL practices.

The book starts with PART I: covering the syntax and rules for stored routines. This part is straightforward and a very fast read. The authors tend to repeat themselves on occasion, though only when relevant.

PART II looks more closely at the particular rules for stored funtions and triggers. It also offers a transaction managing chapter, which describes transactions in MySQL in general, and in stored programming in particular. This chapter is very informative.

PART III discusses the use of stored routings from external programs: PHP, Java, Perl, Python, .NET. The authors establish their view of correct usage and provide with general recommendations.

In general, these three parts cover the stored routines material.
However, here comes a nice surprise: enter Part IV, which is a real gem.
This last part of the book discusses in depth MySQL query optimizations, indexing methods, performance issues, most unrelated with stored programming.
Why? The authors explain (and I agree with them), that most stored routines code will usually have SQL queries DML statements in them. It is their opinion, then, that to write good, efficient, stored procedures, one must be aware of how MySQL optimizes and handles complex queries.
I am not new to MySQL, yet have learned quite a few new things from this last part.
The book ends with a "best practices" chapter, which mostly provides summary for all issues discussed in the book, including some general recommendations for best practices in programming (which could have been left out, in my opinion).

All in all, this book is certainly a very good reference for anyone wishing to write stored functions/procedures/triggers in MySQL. The authors certainly have a strong expertise on the subject, and have a lot to tell.

'MySQL Stored Procedure Programming' by Guy Harrison is a wonderful book for any MySQL developers out there in the world. With the release my MySQL 5.0, stored procedures/functions and triggers were finally added, making MySQL a real-world database that could successfully compete with SQL Server and Oracle. While nowhere near as bloated as those 2 behemoths, MySQL has a rich, loyal following that loves this 'little database that could', but until the latest version, what it could do was good, but not good enough for many people.

Having MySQL 5 and the ability to now write stored procedures, this DB could be used to power even the most important of web applications. Having this book in your hands now gives you the power to learn how to perform this very task efficiently and effectively.

I love the writing, size, and great layout of this text. In true O'Reilly fashion it's packaged for the masses and it is a pleasure to learn from.

***** HIGHLY HIGHLY RECOMMENDED

This book clearly covers stored procedure programming well. Of course, it goes over basic syntax and provides examples, but it also goes much farther than that. This book discusses optimization of MySQL queries regardless of the use - in or out of sprocs. It also did a very nice job of discussing the use of cursors - the ability to iterate through the results of a query without being pelted with the entire result set all at once.

If you're developing on MySQL 5 or greater, and you're serious about letting the database handle things that make sense (i.e. denormalization, administration, and putting business logic into the database), this is an excellent resource.

Hit(s):

o Thorough coverage of
- o stored procedures
- o functions
- o triggers
- o cursors
o Explains stored procedure optimization very well
o Serves as stored procedure cookbook
o Excellent coverage of stored procedure best practices
o Demonstrates use of stored procedures with languages like PHP, Perl, Java, and others.

Miss(es):

o Title doesn't do it justice.

This is the first and only book about Mysql stored procedured and since it was written by the query tuning guru Guy Harrison, it also includes nice tips on query tuning. Highly recommended, just be forewarn that this is for advance Mysql developers or DBA only. Also, be aware that Mysql stored procedure as of release 5.0 and 5.1 won't buy you much performance since Mysql parse stored procedures scripts every time it run unlike other RDBMS like Oracle and MSSQL. If you want better performance, you should make use of prepared statements inside a stored procedure.

Are you a MySQL programmer? If you are, then this book is for you. Authors Guy Harrison and Steven Feuerstein, have done an outstanding job of writing a book that will help MySQL practitioners realize the full potential of MySQL stored programs.

Harrison and Feuerstein, begin by introducing the MySQL stored program language and provide a detailed description of the language structure and usage. Then, the authors describe how you can use the MySQL elements to build functional and useful store programs. The authors then show you how to use the stored programs within applications.
Finally, they show you how to get programs to work correctly by making them perform efficiently, robust and secure, and be easily maintained.

This most excellent book describes the stored program language introduced in MySQL 5.0. More importantly, this book will help you get the job done!!

This is a fantastic book. I work as a software tester that works with MySQL in some capacity every day. With the help of this book I was able not only understand the stored procedures our developers were writing up but I was able to write my own procedures and functions with ease.

It's a fairly dry book but the information is fantastic. I would highly recommend this book to anyone who wants to learn more about stored procedures using MySQL.

This book is great. Concise and I recomended it for everybody who need learn about Mysql Storage Procedure. It is the best buy.

Great book, excellent explanation, covering the very advanced usage and power of Stored Procedures capability in order to bring greater efficiency of application.
Very clear style of writing, good examples with a detail explanation.
Definitely recommended book.
