MySQL User Conference
Employee +0 Vote Up -0Vote Down

Long time no speak! Hey non-avid readers!

I’ve been keeping my head down lately working away in our support group, and haven’t had much time to get any tips down on my blog or even any thoughts in general.

Over the past few weeks I’ve been polishing up my presentation - MySQL for Oracle DBAs, which is on the last day - next Thursday, April 27th.

http://www.mysqluc.com/cs/mysqluc2006/view/e_sess/8465

If you’re reading this - and around at our user conference next week - seek me out and say “Hi!”.

I’ll work on a number of blog posts after the conference, which will give some of the information available in my presentation as well.

Look forward to saying “Hi!” to as many of you as possible!

Stripping Digits - The benefits of Benchmarking and Profiling
Employee +0 Vote Up -0Vote Down

Carsten Pedersen (Certification Manager of at MySQL AB) read my entry about stripping digits, and has done a good write up here on how this function could be improved, a great deal.

Have a read of Carstens link, and my previous entry if you didn’t catch it, before we progress.

As you see, I mentioned that “it performed fairly well”, but I admit given the nature of the request (a quick IRC question) I didn’t run a benchmark on it compared to something like Carsten’s REPLACE solution. I actually went with the REGEXP as the original question was actually something along the lines of “If I have a string such as “joe123″ how I can I strip the digits from the end to return just “joe”. I wrote the quick function as an example of what you can do in 5.0, as the user was still 4.x

MySQL 5.0 - Source Documentation
Employee +0 Vote Up -0Vote Down

Wow what a hectic month - just logged on and noticed I haven’t updated the site in a month! I have a part done entry on triggers that I haven’t had time to finish yet, look out for that in a couple of days. Work has been hectic, a lot of work going in to the MySQL Module of NORAD (a system/database monitoring tool that we distribute.. But that’s a story for another day), which I’m responsible for building the collections / window definitions for at the moment.

One of the windows I was building today was for “Open Tables” - sourced from SHOW OPEN TABLES; - yet I wasn’t entirely sure on what all of the output meant. Specifically “Name_locked”. The documentation doesn’t comment on this at all (the documentation for SHOW OPEN TABLES is particularly poor, even noting a “Comment” field that simply doesn’t exist (on 4.1 at least).
