Join us for a live webinar (http://www.mysql.com/news-and-events/web-seminars/display-630.html) and download a new whitepaper (http://www.mysql.com/why-mysql/white-papers/mysql_wp_session_mngmnt.php) where we discuss how to realize new value from data collected during web session management.

Session management has long been a key component of any web infrastructure – enhancing the user browsing experience through improved reliability, reduced latency and tighter security.

Increasingly organizations are looking to unlock more value from session management to further improve user loyalty (i.e. making the web service more “sticky”) and improve monetization of web services. There are two distinct developments that offer the promise of unlocking more value from session data:
1. Provide highly personalized browsing experiences by

I am going to Madrid, Spain, to participate in the Open Communities Forum on June 18-19.
As usual with Sun open events, the agenda includes several actors in the open source arena, such as MySQL, Java, Open Solaris, with topics ranging from web development to mobile integration.
It looks promising, and I look forward to this event, which is my first one in Spain.
On the first day, I will do an introductory talk about MySQL, and a more technical workshop for advanced users. The second day will be mainly dedicated to meeting users in the area, but I will also do a guest appearance in a talk about

The MySQL Campus Tour 2009 started very well at Cal Poly, San Luis Obispo, CA.
Despite the warm day, which would have tempted many attendees to desert the conference and go to the nearby beaches, there was a full room, with 82 people, many of them standing.
The presentation was appreciated (and so was the pizza that Sun had delivered to the classroom). I did the main part, while Sheeri was actively contributing with witty and informational remarks.
Most notable, after the session, we continued the cultural exchange to a local restaurant that bears my name (correctly spelled!), where this heap of bread caught my eye. Thanks to

I am looking forward to the MySQL Users Conference and Expo 2009. Since I am a tutorial speaker, my choice of tutorials to attend is limited. Upon completion of my duties, I will attend Greg Haase's tutorial on Build and Release Management for Database Engineers.
There are many reasons for that. For starting, Greg is the winner of the MySQl 5.1 Use Case competition where he has shown his DBA skills, and then, he is using the MySQL Sandbox

South Californians, mark your calendars! On February 24th at 7,30pm the Los Angeles Meetup Group will host Chris Schneider, Facebook DBA, who will talk about "Scaling MySQL".

Now, if I talk about scaling MySQL, I will refer to personal experience in my consulting career, when 10 million people connected all at once to my customer's web site. You may be interested in the story or simply yawn. But when a Facebook DBA talks to you about scaling, 10 million connection is low traffic, and scaling takes a completely different meaning.

(edit) mysql, session, workaround, delete, variables

I've come up with some interesting workarounds for missing features using @session variables and I'd like to share one with you today: DELETE ... JOIN ... LIMIT N;

okay, so we've got two tables, one with many duplicates and one with no duplicates.
We want to join the tables using 'id', but only want to delete N duplicates from t1.
MySQL's DELETE does not include LIMIT support when JOIN is used, so we need to work around
that using some fancy footwork:

mysql> select * from t1;
+------+------+
| id | abc |
+------+------+
| 1 | 1 |
| 1 | 1 |
| 1 | 1 |
| 1 | 1 |
| 1 | 1 |
| 1 | 1 |
| 1 | 1 |
| 1 | 1 |
+------+------+
8 rows in set (0.00 sec)

mysql> select * from t2;
+----+------+
| id | xyz |
+----+------+
