AskTOM Office Hours: Hash Joins and Database In-Memory
 
01:13:30
Held on April 20 2018 Andy Rivenes (@TheInMemoryGuy) and Maria Colgan (@SQLMaria) focused on a deep dive into hash joins and how they are used with Database In-Memory to make joins lightning fast. The session began by reviewing how traditional hash joins work and then addressed Bloom filters and how Database In-Memory uses them to effectively turn hash joins into scan and filter operations. The use of Join Groups was then discussed as a way to further enhance join performance in 12.2 and beyond.

Query Tuning 101: How to Compare Execution Plans
 
04:12
When you're tuning SQL query there's two important questions to keep in mind: * Have my changes made any difference? * If they have, is performance better or worse? In this video we'll look at how you can use SQL Developer to compare execution plans. This will enable you to differences between them and determine which plan performs better. ============================ The Magic of SQL with Chris Saxon Copyright © 2015 Oracle and/or its affiliates.

Does SQL table join order matter?
 
14:10
Have you ever wondered if the order of the tables in your FROM clause matter? In today's video, we look at why theoretically table join order *does* make a difference for performance and why SQL Server doesn't use the order you provide. We also look at different techniques for forcing SQL Server to use the join order you specified.
