SQL Server Query Tuning & Optimization
2022TL; DR
This full-day seminar will show you how to optimize SQL Server queries and create high-performance applications. You will learn about the inner workings of the query processor so you can write better queries and provide the query processor with the quality information it needs to produce efficient execution plans. You’ll also get tips for troubleshooting underperforming queries.
Session Details
This full-day seminar will show you how to optimize SQL Server queries and create high-performance applications.
You will learn about the inner workings of the query processor so you can write better queries and provide the query processor with the quality information it needs to produce efficient execution plans. You’ll also get tips for troubleshooting underperforming queries.
Topics include:
- Learn about query processing improvements on SQL Server 2022
- Learn about intelligent query processing
– Understand how the query optimizer works
– Troubleshoot queries using extended events, SQL trace, dynamic management views (DMVs), the data collector, and other tools
– Work with query operators for data access, joins, aggregations, parallelism, and updates
– Speed up queries and dramatically improve application performance by creating the right indexes
– Understand statistics and how to detect and fix cardinality estimation errors
– Maximize OLTP query performance using In-Memory OLTP features, including memory-optimized tables and natively compiled stored procedures
– Monitor and promote plan caching and reuse to improve application performance
– Improve the performance of data warehouse queries using columnstore indexes
– Handle query processor limitations with hints and other methods

Dive into the Query Optimizer-Undocumented Insight
This 500 level session will focus on using undocumented statements and trace flags to get insight into how the query optimizer works and show you which operations it performs during query optimization.
Understanding Parameter Sniffing
This session will show you how parameter sniffing works and in which cases could be a problem. How to diagnose and troubleshoot parameter sniffing problems and their solutions will be discussed as well.
