Post date: Mar 08, 2022 12:29:7 PM
This will be a Beginners session highlighting the starting point for using the execution plans from SQL Server to assist in query tuning. Briefly, we will look at the history to get an idea of how Microsoft has improved the display through Graphical Plans and Missing Index suggestion. What is the difference between a Table and Clustered Index Scan? What is a Lookup? How do you improve performance of Lookups? What are the different types of Loops? How to get more information from the Plan with the properties window? We might even look at the Query Store.
