WTF worthy man page suggestion...
+0 Vote Up -0Vote Down
I encountered the following text in a man page. Please tell me that I am not alone in thinking that the "typical" solution suggested is WTF worthy...

After calling "commit" or "rollback" many drivers will not let you
fetch from a previously active "SELECT" statement handle that's a child
of the same database handle. A typical way round this is to connect the
the database twice and use one connection for "SELECT" statements.


If the programmer really wants to reuse values from a SELECT statement which occurred within a transaction after the transaction is closed, they should cache those values themselves by populating some variable within their application. IMO, they definitely should not be using multiple connections to the same database from one unit of work unless they are

review: MySQL Cookbook
+0 Vote Up -0Vote Down

Last year O’Reilly released the 2nd Edition of the  MySQL Cookbook by Paul DuBois.  You can read my review here.

Whenever a publisher releases a 2nd Edition of a book, you know it was well received the first time around.  So that’s a good sign that the material has gotten people buying.  I would say in the computer reference and howto market, that’s a very good indication that the material is well written and relevant.  I certainly found it to be the case with this title.

If you’re looking for a quick & no nonsense howto book on MySQL development, look no further.  The book focuses on Ruby, Perl, PHP, Python and Java as examples.  So if you’re doing development, specifically web development, you’ll get a lot out of this title.

review: High Performance MySQL 2nd Ed.

I just finished reading the recently released 2nd Edition of High Performance MySQL by Baron Schwartz, Peter Zaitsev, Vadim Tkachenko, Jeremy Zawodny, Arjen Lentz & Derek Balling.  I’ve posted a review here on Amazon.

Wow, that’s quite a list of authors, but when you look at the material, you see why.  This book is a very indepth look at the MySQL server.  Intended for the intermediate to advanced DBAs and developers who want to know the inner workings of the server, as well as how to use many of it’s advanced features.

For instance the chapter on replication was quite good.  Given that you probably setup replication in five minutes, and are wondering weeks or months

Review of AssemblySys dataServices
+0 Vote Up -0Vote Down

On a large data migration project that I am currently spearheading, we have a large installed userbase of over 2 million users running on a social networking engine. The schema has been redesigned from scratch, and code is being written to match the new schema, using the all-powerful MySQL database as the system to manage all that data.

Since this social network is global, we need good and reliable location information. The current location model is flawed and full of holes, so we have chosen AssemblySys‘ data to replace it.

We are not using AssemblySys’ schema, as we’ve rolled our own. I’ve designed our new schema to be hierarchial in nature, treating all locations on the planet as ‘nodes’ with a tree relationship, with “Earth” being

review: Backup & Recovery by W. Curtis Preston
+0 Vote Up -0Vote Down

Just finished up O’Reilly’s Backup & Recovery by W. Curtis Preston.  The title is wide-reaching, covering backups at the operating system as well as on all the popular database platforms, including Oracle, MySQL, Postgres, Sybase, SQL Server and DB2.  Preston has an amazing grasp of a spectrum of technologies and platforms, and as an Oracle & MySQL DBA myself, I’d use this as my backup reference text any day.

I’ve posted my review of Backup and Recovery over at Amazon.

Thoughts on Google Chrome
+0 Vote Up -0Vote Down

So Google Chrome – Google's attempt at an open source browser, came out yesterday and I took it out for a spin. At its heart is the Webkit engine (also open source) and Google Gears, powered by SQLite (can MySQL rival SQLite in applications like this?). Here are my thoughts.

  • Fast – Chrome loads extremely fast, blazing even. Granted, my Firefox would probably load fast if I didn't have any addons as well. Sites like

Reviewing MONyog
+0 Vote Up -0Vote Down

I was contacted by the folks at MONyog and asked if I would review MONyog. Since using MONyog is something I have been wanting to do for a while, I jumped at the chance. Of course, “jumped” is relative; Rohit asked me at the MySQL User Conference back in April, and here it is two months later, in June. My apologies to folks for being slow.

This review is an overall review of MONyog as well as specifically reviewing the newest features released in the recent beta (Version 2.5 Beta 2). Feature requests are easily delineated with (feature request). This review is quite long, feel free to bookmark it and read it at your leisure. If you have comments please add them, even if it takes a while for you to read this entire article.

While the webyog website gives some information about what MONyog can do, it is a

Book review: "Xen Virtualization" by Prabhakar Chaganti (Packt Publishing)
Employee +0 Vote Up -0Vote Down

I recently received a review copy of the book "Xen Virtualization" by Prabhakar Chaganti (Packt Publishing) and finished reading it a few days ago.

The subtitle "A fast and practical guide" is a matching description - I managed to read the ~130 pages over the course of a week. The book is by no means an exhaustive reference manual, but it gives the reader a good overview about Xen and assists with performing the first steps and getting started.

The Kysoh Tux droid toy. First impressions
+0 Vote Up -0Vote Down
I just unpacked and started setting up the Kysoh Tux toy that I got at OScon. The lucky folks with a press badge were given a free one. I had to pay for mine.

The good:

Physically, it feels to be well and solidly made. It didn't feel like they were being cheap with the fabrication. It weighs just over half a kilogram.

Physical setup is straightforward. Unstrap the parts from the box. Click in the US power module into the internationalized power cord. Plug in the penguin unit, to charge it up. It can operate both plugged in, and on internal batteries, which it charges itself. Plug the fish unit into your computer with the included USB cord. It uses a mini-usb plug.

Book Review: Understanding MySQL Internals.
+0 Vote Up -0Vote Down
I actually received this book about a month ago but from necessity, I had to put it to one side and deal with more important issues. It is not a big book, only 235 pages, but it has an easy to read conversational style, unlike similarly titled technical books on the internals of other software.

If you're looking for a book about database theory, this book is not for you. It conveys to the reader a good overview as how MySQL functions without delving into the theories as to how the algorithms work or the rationale behind their design. The book does a good job of at least giving a drive-by look at most of the significant components of MySQL. libmysys, MySQL's platform library which allows MySQL to work on a very wide range of operating systems is mentioned only under the subsection titles 'Core API' and 'Utility API' and only lists about 30 of the functions available:

A review of MONyog
+0 Vote Up -0Vote Down

This is a review of Webyog's MONyog MySQL monitoring tool. The product is still in beta and has some rough edges, but holds promise. Its design includes some interesting architectural decisions I think will help distinguish it from MySQL's own Monitoring and Advisory Service.

MySQL Table Sync vs. SQLyog Job Agent
+0 Vote Up -0Vote Down

When I wrote my first article on algorithms to compare and synchronize data between MySQL tables, Webyog's Rohit Nadhani left a comment on the article mentioning the SQLyog Job Agent, which has a similar function. Although I have been developing MySQL Table Sync essentially in isolation, I have been meaning to give SQLyog Job Agent a try. I recently did so, and then followed that up with an email conversation with Rohit. This article is about my experience using the SQLyog Job Agent from the command line, some thoughts on the algorithm as best I can deduce it, and benchmark results against MySQL Table Sync.

A review of the Glom graphical database front-end
+0 Vote Up -0Vote Down

Glom is an interesting graphical database front-end I've been meaning to try out for some time. Someone asked about graphical database front-ends on the #mysql IRC channel recently, and that prompted me to install Glom and learn how to use it. My overall impressions? It lands squarely in the middle of its target audience's needs, but still has a quirk here and there. With a bit of polish it will be a fine product, and it's already a winner over Microsoft Access and Filemaker, two similar programs with which you might be familiar. In this article I'll walk through installing and configuring Glom, a simple database design, a quick peek under the hood, an archaeologist's experiences using it, and give my opinions about Glom in detail.

Forta's MySQL Crash Course
+0 Vote Up -0Vote Down

Ben Forta sent me a copy of his latest book: MySQL Crash Course a book based on his: Teach yourself SQL in 10 minutes book.

MySQL Crash Course is a concise guide (it's actually about the size of a novel, but 300 pages) to MySQL. I am a big fan of short and to the point books. Good job keeping it short Ben, I know you have written some hefty ones. ;)

The book doesn't focus on the system administration of MySQL, but rather the programming side of things - SQL.
