SQLSaturday Cape Town Precon-Understanding Execution Plans with Hugo Kornelis

Hugo has almost 20 years of SQL Server experience in various roles. He has a strong database design background but also loves to write and tune complex queries.
For troubleshooting long-running queries, looking at the execution plan is often a good starting point. Once you know how the query is executed, you know why it's slow and what you can do to speed it up.
But what if the execution plan is just beyond your understanding? What if it uses operators you have seen before, but do not really understand? What if you look at the execution plan, but just don't see the problem?
In this full-day workshop, you will learn everything you need to be able to read and understand any execution plan. We'll start with an overview of execution plans as a whole, and then dive in and look at all the components, and how they fit together. This will increase your understanding on why the optimizer picks a plan, and what you can do to make it pick a better plan.
Whether you have read your share of execution plans or whether you wouldn't know where to find them, this workshop will teach you everything you need to know about execution plans.
