MySQL Cookbook
Michael J. Ross writes "Of all the technical challenges faced by the typical experienced computer programmer, questions about syntax form a relatively small portion. This is especially true now that current coding editors and IDEs offer statement expansion and syntax checking. Rather, the most common type of technical challenge is understanding how to solve a specific data access or manipulation problem. Hence the growing popularity of programming "cookbooks," which are filled with "recipes," each comprising a concise statement of a focused problem, followed by a solution, with plenty of sample code to show how to implement it. For developers using the MySQL database system, the gold standard of such books is MySQL Cookbook, by Paul DuBois." Read below for the rest of Michael's review

summary
A great book for developers using the MySQL database system
Published by O'Reilly Media, the second edition appeared in November 2006. This new edition has been updated for MySQL version 5.0. The publishers have a Web page devoted to the book, where the visitor can find both brief and full descriptions of the book, an online table of contents and index, a sample chapter (number 5, "Working with Strings") in PDF format, errata (none reported as of this writing), and a way to post your own review on the O'Reilly Web site. There are also links for purchasing the book, or reading an online version, in the Safari Bookshelf program.
The bulk of the book's material is divided among 20 chapters, covering a wide range of topics: Using the mysql Client Program; Writing MySQL-Based Programs; Selecting Data from Tables; Table Management; Working with Strings; Working with Dates and Times; Sorting Query Results; Generating Summaries; Obtaining and Using Metadata; Importing and Exporting Data; Generating and Using Sequences; Using Multiple Tables; Statistical Techniques; Handling Duplicates; Performing Transactions; Using Stored Procedures, Triggers, and Events; Introduction to MySQL on the Web; Incorporating Query Results into Web Pages; Processing Web Input with MySQL; Using MySQL-Based Web Session Management.
Most of these chapters contain a generous number of sections, each serving as a recipe for a specific problem within MySQL. Two of the chapters have only four such recipes, but most have a dozen or more, with a few of them boasting more than three dozen recipes. Each recipe begins with a brief problem statement, and usually an equally brief solution statement, followed by a much more lengthy discussion, which contains the actual explanation of the solution, the sample code, and the expected output of that code. Some of the sections conclude with a mention of related recipes that could also be consulted.
This book, like so many other programming cookbooks, is weakened by the practice of offering a "Solution" subsection that consists of only one or two sentences — so terse and high-level that it provides, for all practical purposes, no solution to the reader. The actual solution is found in the "Discussion" subsection, which follows. This practice makes no sense. Because both subsections address the problem solution, they should be combined into a single subsection, naturally labeled "Solution." It appears that the purpose of the current Solution statements is to provide a terse summary. If so, then it should be labeled as such, yet still included within the new Solution subsection.
Despite this illogical division of each solution into two subsections, the content of the problem solutions found in MySQL Cookbook should be quite valuable, for several reasons: Firstly, the author has chosen the sorts of problems, within each category, that the MySQL programmer would typically encounter. No doubt this is a consequence of Paul DuBois being the author of a number of MySQL books, as well as one of the earliest contributors to the online MySQL Reference Manual. Secondly, the solutions work, and have been demonstrated to do so. Thirdly, the writing style is straightforward, which is characteristic of O'Reilly's titles. Fourthly, all of the problem solutions contain sample code and its output, which not only demonstrate the validity of each solution (as noted in my second point), but also allows the reader to see how the solution works simply by reading the material, and not having to type in the sample code to get the output within their own development environment — assuming one is even at hand, when reading the book.
The bulk of MySQL-related code in use today, was created not just to be accessed within a database client program, such as mysql, but instead from interpreted programming languages — especially those used heavily on Web sites. This is one area where MySQL Cookbook really shines, because it contains a large amount of sample code in Perl, PHP, Python, Java, and even Ruby. That is not to say that every code sample in one language has corresponding samples for all of the other languages; that would undoubtedly make the book much longer than it currently is, and probably unwieldy. But in cases where all of the languages are capable of expressing brief solutions, then they are included.
Regardless of whether the reader chooses the print or online versions, there are roughly two ways to make use of this book. If a programmer wishes to significantly increase their knowledge of what MySQL can do for them, and also increase their comfort level with utilizing those capabilities, then they might elect to read the book from stem to stern. Given that this would involve reading over 900 pages, it would certainly take some time for the average developer, but arguably could be time well spent. At the other end of the spectrum, the reader might elect to peruse individual sections that look interesting — particularly if they are relevant to a current project. This approach is certainly doable, because each of the recipes is self-contained, without the cross-referencing seen in many non-recipe style books. Admittedly, there are some "See Also" sections, but they are relatively few in number, with largely optional information, and tend to simply enrich the book's presentation, rather than frustrating the reader by pointing to other areas of the book.
This new edition of MySQL Cookbook concludes with four appendices, and an index. The first appendix explains where to obtain the software for MySQL, the five API programming languages used in the book, and the Apache Web server. The second appendix shows how to execute programs written in those five interface languages, on the command line. The third appendix is a fairly substantial primer on Java Server Pages (JSP) and Tomcat, providing an overview of servlets and JSP, as well as how to install and set up a Tomcat server, the Tomcat directory structure, the basics of JSP pages, and more. The last appendix lists resources outside the book for MySQL and the five aforementioned languages.
Unlike far too many programming books on the market now, this book's index is generally quite thorough, which is essential for a work of this size (975 pages). The recipe titles in the table of contents, are detailed enough to make it possible for the reader to locate the appropriate recipe in the book for their particular problem — assuming the book addresses that problem — and are grouped by subject, making it easier to find related recipes, which oftentimes can provide insight into other problems that they do not address directly.
Despite the obvious effort that has gone into both editions of this book, there are still some areas for improvement, and most of them are related to the readability of the sample code. Admittedly, there are different schools of thought as to optimal coding style, including use of whitespace, the placement of braces, and other matters. This assessment can only be my own opinion, based upon years of reading other people's code. The sample code in MySQL Cookbook would be more readable if more whitespace were utilized to separate function and variable names from open and close parentheses. This is especially true for the SQL code and MySQL extensions, for which all of the keywords are in all uppercase. The code fragments and full programs written in the API languages — such as Perl and PHP — are more readable, though they sometimes suffer from nondescriptive variable names. One might argue that the aforesaid choices are needed to cut down on the space consumed by the code on the book's pages. But if that were true, then the author likely would not have wasted an entire line for each open brace. Last, and certainly not least for the programmer who would like to try out the author's sample code in their own environment, it is unfortunate and inexplicable as to why the sample code is not offered on the O'Reilly Web site for downloading.
All in all, MySQL Cookbook is a well-organized and neatly written work, which should be of tremendous value to any software developer trying to find proven solutions to common database programming problems.

or something
I have the PHP Cookbook and there are many useful tidbits, but this axiom applies "there is more than one way to code an Application" so I find them more a good resource for ways to do things I didn't know existed, but not necessaily the way that best suits me or my needs.
:-)
I had a chance to skim through the MySQL cookbook a week or so ago and will more than probably pick one up, though I think I need another shelf for my web development/linux books.
irCertaninly the ORielly programming series are very nice books indeed. Not quite used to their Linux OS books yet from them, the Wiley ones are more approachable.

I'm wondering if there's an emphasis on security measures relating to web-app dev. I'll have to pop by the bookstore and thumb through.
;)
Need to do that anyway, as my last O'Rly book (JavaScript Definitive Guide) has a split in the binding and does not have the nice "stay open" binding like some of the other newer titles. I really need to hold the books in had to see if it has binding issues, Amazon is not up to speed in that respect yet.

SELECT recipe FROM cookbook WHERE ingredient = 'Refried Beans'
I noticed there was a recipe which I'd like to see which was not covered. Is there a recipe for don't treat my data as garbage by default?
It was brought up in a reply to a comment here on Slashdot by Marten Mickos, CEO, MySQL AB. I've not heard if they managed to help out the people who are effectively forced into using MySQL but would rather not.
A MySQL cookbook reminds me of something I would use in college while learning to live flat broke. Great ways to spice up the old Hamburger Helper, Macaroni and Cheese, etc. You gotta be kidding me. The last time I checked out MySQL was a couple of years ago and then there were so many gotchas I wondered how heavy CRUD production apps could consider such a DB. It's like the MySQL designers figured rather than enforce data integrity and reject invalid transactions they would just kinda guess what you wanted and then put something into the DB on your behalf.
I sat in on his panel at Vancouver's PHP Conf. last month and found him pretty informative... if not a little bit boring while presenting it.
Of course it was the first or second panel of the day, I don't think many people can get too excited about statistical analysis queries of world wide PHP users at 8 in the morning.
It usually takes a couple of weeks for authors to re-enter society to the extent that they can extract the sample code and massage it into a releasable form. (For me it takes months, but I'm a bad example.) I assume that's what happened here.
how to invest, a novice's guide
I've been emailing errata to Paul from two of his books over the span of several months now and he's simply not updating the on-line errata pages. For example, the errata page for "MySQL and Perl for the Web" hasn't been updated since 2006-07-25; since 2006-02-11 for "MySQL"; and "MySQL Cookbook, 2nd Edition" has no errata at all yet it's a 975 page book.
Paul, your writing is first rate and I love everything about your books. I hope you are well--and get the errata updated soon, please.
BTW: Paul literally writes his books--with pencil and paper. In a coffee shop.

Maybe the author should have spent his time writing about a better RDBMS.
Check out Fred's blog post where he's trying to find MySQL people.
Aways funny to see these removed-from-the-trenches guys who think the solution to making their startup spaghetti code perform is to bring in a database guy/gal. We all know how this goes... the startup's founders/coders stonewall the database pro because they don't want anyone to see how shitty their code is.
So yeah, it's a joke to think that someone's going to come in and make everything go faster now, but hey, good chance to grab some of that VC money before it goes away.

I'd recommend trying their online library, which most certainly contains this book as well as about 10000 others on a wide variety of subjects, ATM. I used Safari last month and it was really amazing!! I plan on renewing my subscription when I have more reading time...
The dangers of knowledge trigger emotional distress in human beings.
So, the most common question novice programmers have is 'how do i program'? Am I the only one who read the review like that?
If you miss the underlying concept of being able to take pieces of functionality and use them to create additional functionality; no book can help you.
well I went to oreily and tried to buy it, but no ebook version - so I tried another online shop that sold it in e-book version got all the way to checkout and their payment processor site was down. So now I am going to open emule and get it there, can't say i didn't try to pay the $10...
HAHAHAAHAHAAH
Hence the growing popularity of programming "cookbooks," which are filled with "recipes," each comprising a concise statement of a focused problem, followed by a solution, with plenty of sample code to show how to implement it.
Of course, another option is to learn the "fundamentals" and "theory" of data management, so that you can "understand" data management at a more "abstract" and "fundamental" level, instead of relying on "cookbooks" and "recipes" that you can copy mindlessly. Then you can save "money" on "cookbooks" when the "next big thing" comes around, because you already "know" that it's the "same thing" with "different syntax".
Imagine a "heart surgery cookbook" for newbies? A "bridge designing cookbook"? An "accounting cookbook"? What do you think of surgeons, engineers, or accountants who carry those around, tucked under their arm?
On the other hand, it's quite "profitable" for "consultants" like "me" to come in a clean up the "garbage" that the "cookbook"-using "idiots" "write".
(I guess all the "quotes" are a nod to MySQL's ability to accept strings in place of other types? Is there a recipe to fix that?)

'nuff said.
MySql Cookbook? Fuck. What a waste of time. GET OVER IT FANBOYS - IT SUCKS and IS NOT FREE.
Postgres is better (the glaringly obvious replacement).
Firebird is better
MSSQL Express is better
Oracle Express is better
catshit pancakes are better.
Why the almighty "they" let you goddamn noobs continue working with that fucking POS glorified datastore is beyond common sense and well past insanity.
I love the Perl Cookbook, nearly the single most useful book I own. I recently started working on some Perl/MySQL stuff again about a month ago, so I bought this book. I have not found it as useful. Now, this may be because I'm not a MySQL power user, I poke at it about once a year, just infrequently enough that I have to relearn everything again-- but you'd think this would be exactly the book I need.
There's very little on subselects-- in fact, in trying to provide a page count, I can't find subselect in the index, even under select. The JOIN information is scattered through a few related recipes and is okay, but just okay. I had a pretty complicated (for me) SELECT statement I was trying to do, a LEFT JOIN with some WHERE information and a subselect with some other stuff...I don't recall the specifics, but the book was only moderately helpful, I wound up just trial and erroring my way through until it did what I wanted. There is some general management info, but no password recovery? Everytime I have to touch MySQL, step number one for me is typically password recovery, as I've forgotten everything since the last time.
It's a big book, and seems to cover a lot of ground (for example, about 70 pages of recipes relating to dates), so I'm sure there's some good in here. With the Perl Cookbook, I can't say that I've used the whole thing, but there are particular sections that I return to again and again (custom sorting on hash keys, etc...) The MySQL Cookbook just doesn't seem to be syncing up with my problems the way the Perl Cookbook does. I use more Perl than MySQL, though, so maybe it would do better if you knew MySQL in more depth than I do. It may be a problem with my limitations, but then again, I would have thought a Cookbook would be exactly the book to help.
1. Place "database" in dehumidifier.
2. Leave for 1 week.
3. "Database" should be dry. Check.
4. Using 1500 grit sandpaper, gently sand, taking care that your "database" does not suffer an integrity failure, otherwise you will need to begin with a new "installation". NB: Do NOT use wet n' dry.
5. Repeat step 4 with 2000 grit sandpaper, then buff with lambswool.
6. Apply Mequire's Gold Class polish, then buff dry with a terry cloth.
If they started doing that, then they couldn't make all those pretty graphs showing how fast their "database" is compared to their competitors. But it also allows them to have checkbox compliance.
Imagine a "checklist" for a pilot! What would you think of a pilot with a checklist tucked under his arm? I'd hope that my surgeon had a checklist too, that way I'd be far less likely to get an X-ray several years later revealing a surgical instrument left inside me.
Concerns over the (dubious) trustworthiness of MySeQueL to hold your precious data aside, a good recipe can prove invaluable for reasons besides making sure you're not forgetting anything.
I'm an engineer. At some stage, you have to understand the theory. However, I find that I learn best by osmosis. If I first learn how to do problems, then I have a context to place the theory and a motivation to learn it.
Do you build your skill as a writer by picking up Elements of Style, a dictionary and a book on grammar, or first addicting yourself to reading novels and then reading about theory? For most people it's the former. It's also how you learned spoken language as a child. The brain is in fact very well adapted to that mode of learning.
The problem is not with cookbooks but with people who have no desire at all to learn the theory, or who don't ask "What could I be potentially screwing up by taking this approach?".
If I have seen further it is by stealing the Intellectual Property of giants.
How is this newsworthy?
