Today, March 22nd, is Bum Rush The Charts Day.  This is a day during which thousands of independent podcasters and bloggers will attempt to show the strength they have compared to traditional corporate media. How?  By making an indepedent single the #1 item on iTunes.  You can support this effort by buying the song "Mine Again" by Black Lab, a band that was dropped from two labels and had to fight back to get the rights to its own music.  Every commission made on the sale of the song is being donated to support college scholarships and 50% of the royalties the band earns will also be donated.  If you believe in podcasting and …

From time to time, MySQL employees are approached with proposals from universities and other research institutions about MySQL participating in research programmes financed by governmental initiatives in the US and in the EU. This is much appreciated. Often, there is a mutual interest, where

• academics need an industrial partner to anchor the results of the research into a real-world application and even to fulfil the requirements of getting a grant, and
• the MySQL user community needs new features in MySQL Server, or in the Connectors enabling the use of MySQL from various development environments.

I used to wear glasses (was nearsighted), but through some natural processes that I won’t go into here, I actually reversed my nearsightedness and now see clearly without the need for glasses. Having clear vision is a great thing, both for individuals and for companies.

One of the terrific aspects about MySQL is that the vision for the database is established with the help of the very active and innovative community of MySQL users who are daily pushing and extending the MySQL database server to do new and exciting things. We are in the process now of crafting the future vision of the server, and that process would be incomplete without your input.

Where would you like to see MySQL go in the coming years? What new areas would you like to see MySQL address? What does your business need MySQL to do that it currently doesn’t? We’re not talking about detailed feature requests here, but more of a “big picture” type of thing. …

In May 2007 XAMPP will be five years old and we think this is a good time to think about changes and improvements to XAMPP. That's what this survey is for: to find out what your needs are and what we can do to improve XAMPP in the next major release.

The survey will run for exactly one month (from March 22nd to April 22nd 2007), after which we will publish the results right here.

Thank you for taking the time to complete the survey. We appreciate your feedback and we will use it to make XAMPP even more useful and enjoyable. ;)

If there are any questions you don't want to answer, you don't have to. You choose.

I'll be giving a presentation about CouchDb tomorrow night at the PHP UG Dortmund. If you're in the area, come and say hello.

You'll learn what CouchDb is, why it is so cool and how to use it with PHP. The talk will be in German, but I'll make some material available in English some time after the presentation.

In case you'd like to see this or my High Availability talk at your local usergroup, company or conference, you can find contact information at my website. I'd like to hear from you!

I’m just back from SNAP Innovation, the developers of the Primebase XT (PBXT) storage engine, here in Hamburg / Altona. What a pleasure to visit a company that, despite its closed-source roots, has understood and embraced what Open Source is all about and how it can open up business possibilities!

Left: Paul McCullagh

PBXT is a pluggable storage engine that fits in with MySQL 5.1. It is fully transactional, and supports MVCC. That makes it a good fit for many purposes, but the area where it is an especially good fit is for the industry that SNAP has been serving for the past decades: the publishing industry. No matter whether print …

In my replication environment I had a hardware failure on master host. A 4.5.GB table containing blob images wa corrupted, so I issued a REPAIR TABLE and the effect was to repair the table but also to reduce the number of rows: master table had just 41 rows less than the copies on the slave hosts on a total of a hundred thousand rows.
So, the problem now is how to recover only those rows from a slave and re-populate the master table avoiding to dump the entire table. And how to do that with a single command line instruction?

We can use a couple of mysqldump options.
The first option to use is --where="where_condition", it dumps only rows selected by the given WHERE condition.

So let's try a first instruction.


slave1:/> mysqldump -u root -proot_pwd --where="idimg between 93305 and 93346" mydb images | mysql -h master_host -u root -proot_pwd mydb
