Hotsos Symposium 2010 — Dallas, I’m Coming!

What should you expect coming to the Hotsos Symposium 2010? It’s 3 days packed with sessions on all aspects of Oracle performance optimization whether it’s design, troubleshooting, development, methodologies and processes. Legendary Tom Kyte — who else can you expect for the keynote?! If you take an optional training day with Tanel Poder then you are likely to learn at least as much about troubleshooting Oracle database performance as you do during the conference and probably even more. Every presentation by Tanel has been an eye opener for me. If you’ve seen his material, you’d know what I’m talking about. Now, imagine that it’s not a one-hour session but the whole day! It will fry your brains so this day is for the strongest! :)

Basic Joins and Subqueries Video

Last month at the Boston MySQL User Group, I went through the meanings of INNER, LEFT/RIGHT OUTER, CROSS, NATURAL joins, how to do a FULL OUTER JOIN in MySQL, and what STRAIGHT_JOIN means. I also explained how to recognize when you want those types of joins, and best practices for the semantics of writing joins and design patterns. Subqueries were explained in this session, and some examples of how to think differently so that you end up writing JOINs instead of subqueries. The slides and video are posted here.
