MySQL Webinar: MySQL EXPLAIN, explained

Some time ago, Matt Lord and I delivered a webinar on the MySQL EXPLAIN feature.  This webinar is available for on-demand access here.  Based on the questions we got during the webinar, I want to emphasize that EXPLAIN does not execute the query, it only determines the query plan for the query.  Hence, EXPLAIN will not be able to evaluate how good the chosen query plan actually is.

If you have questions on this topic after listening to this webinar, feel free to ask questions; either as comments on this blog or at the MySQL Optimizer Forum.

You can also access other webinars on MySQL. New webinars will be announced here.
