On April 22, 2021 I will run an SQLpassion Online Training about Statistics & Plan Caching in SQL Server. Statistics are used by SQL Server to estimate how many rows are returned for a given query. Based on that assumption, the Query Optimizer compiles a physical Execution Plan, which is finally executed by SQL Server. The generated Execution Plan is also cached in the so- called Plan Cache for further reuse.
Because of this approach, a lot of different performance problems can occur in SQL Server, especially then when an inefficient Execution Plan is generated and reused over the time. During the webinar I will cover the following areas:
- Statistics
- Auto Create
 - Auto Update
 - Statistics Analysis
 - Multi Column Statistics
 
 - Cardinality Estimation
- Conjunctions
 - Disjunctions
 - Ascending Key Column Problem
 
 - Plan Caching
- Adhoc Query Caching
 - Parameterization
 - Optimize for Adhoc Workloads
 
 - Parameter Sniffing
- Local Variables
 - Recompilations
 - Plan Guides
 
 
This one-day long webinar is primarily for DBAs, Developers, and Consultants who want to make their SQL Server installations faster. Please check-out the this link for more details about the online training (detailed agenda, date, pricing) and how to sign-up.
Thanks for your time,
Klaus
