You’ve conquered my Fundamentals of Parameter Sniffing class, and now it’s time to get to work. You know you have parameter sniffing problems in your environment – and now you need to learn how to fix ’em.

In this 3-day course, you’ll learn:

  • How to spot the common places where plans diverge: parallelism, memory grants, index selection, and join types
  • How to capture good, bad, and terrible plans with the plan cache and Query Store
  • Ways to mitigate parameter sniffing with index changes, query tuning, and database-level settings
  • How SQL Server 2017 and 2019 try (and usually fail) to reduce it with Adaptive Joins, Adaptive Memory Grants, and Automatic Tuning

This course is 100% demos: the only slides are the introductions at the start of the class, and the recap at the end of the class. The rest of the time, we’ll be working in SQL Server Management Studio. Roll up your sleeves and join me!
