MySQL Workbench 5.2 AlphaMy understanding is the MySQL Workbench 5.2 has the core 5.1 modeling features as well as the new Query Browser. The Query Browser has been easy to use but the feature functionality is still in the alpha phase. Adding the Query Browser in the 5.2 release adds a nice dimension of being able to look at the data model, physical table and data very easily. So far I have

Today’s contradiction:

The new variable can be set per-session and globally, and is dynamic. The old variable is not dynamic, and only global in scope. Both default to FALSE in MySQL 5.1.

According to the manual, the new variable:

was used in MySQL 4.0 to turn on some 4.1 behaviors, and is retained for backward compatibility.

That same page notes the following about the old variable:

That’s right — the …

Tomas Ulin - Director MySQL Engineering

This could be your last chance to listen to and quiz Tomas Ulin on his detailed MySQL Cluster knowledge as he has recently moved from being the Cluster Engineering Director to looking after engineering for MySQL Server. Tomas was in charge for the vast majority of the 7.0 development cycle (and many releases before that) and maintained a very detailed knowledge of the technology – including writing some of the code.

Mat Keep will represent the product management team with some introductory material.

I will also be on hand for the Q&A.

The webinar (as always) is free and starts at 16:30 UTC (other timezones listed below) and you can register here. …

For the fourth time in a row, I will be speaking at FrOSCon, one of the most charming open source events in Europe.
Hosted in the bright environment of the Department of Computer Science of the University of Applied Sciences Bonn-Rhein-Sieg, this event will get you hooked from the beginning. The organization is done by volunteers, who have always done an amazing job, with even better results than more expensive and famous conferences.
This year, there will be some more action than ever before. In addition to the main event, the organizers have given away a few developers rooms, to let some projects build their own event within the main one. There will be a Java subconference, and, closer to my interests, the European edition of the OpenSQLCamp 2009, which applies to all open …
