Brisbane Users Group – MySQL Hackfest

Last night we had a number of keen souls at the Brisbane MySQL User Group . I was very impressed to see the majority of people with laptops at hand.

You can download my slides and code examples at my Articles page.

In our hands on Hackfest tutorial we created the new command SHOW USERGROUPS. Before anybody makes a comment, it was stated in the presentation that this command was made a dummy one, and is a poor candidate for two reasons.

  1. The results should be more dynamic, rather then hardcoded into the source tree
  2. USERGROUPS is not an ideal name due to comparisions to Users, Groups, Roles etc

Still it was productive, here was the outcome of our work for the evening.

mysql> SHOW USERGROUPS;
+----------------------+-------------------------+-----------------------------+
| Name                 | Location                | Website                     |
+----------------------+-------------------------+-----------------------------+
| Brisbane Users Group | Brisbane, QLD Australia | http://mysql.meetup.com/84/ |
| Boston Users Group   | Boston, USA             |                             |
