My So-Called Blog

I’ve written an article highlighting some recent developments with XML support in MySQL 5.1 and MySQL 6.0. Topics include:

• Outputting MySQL data in XML format; includes a look at the 3^rd-party lib_mysqludf_xql library
• Getting XML into MySQL; includes a discussion of the LOAD XML statement (new in MySQL 6.0)
• The ExtractValue() and UpdateXML() functions (new in MySQL 5.1)
• Security issues, including a look at a little nasty known as “XPath injection”

You can read it at the MySQL Developer Zone.

Alexander Barkov contributed a nifty stored procedure and a very helpful pre-publication review. Thanks, Bar!

I’ve had an introductory article to MySQL Cluster 5.1 Disk Data published in the September 2006 issue of International PHP Magazine.

If you’re using Cluster or you’re interested in doing so, and you’ve not yet tried out MySQL 5.1, you’ll find that disk data storage makes MySQL Cluster more flexible, scalable, and cheaper to run than MySQL 4.1 and 5.0 Cluster. In the article, I’ve outlined some reasons why this is so. The article covers the basics of creating disk-based Cluster tables, and discusses some Disk Data do’s and dont’s. There’s also some info about some other improvements to MySQL Cluster that are being made in 5.1, as well as some diagrams and sample PHP5 code for accessing a MySQL Cluster. Just in case you’re not that familiar with setting up a MySQL Cluster, I’ve also included a quick setup guide to help you get started.

You can read more about the article or download the PDF version from the International PHP September TOC page. A single issue is €4.00 or you can get a year’s subscription for €42.00.
