SQL Server Query Optimizer by Fabiano Amorim

Abstract

This full day training conference aims to empower the SQL Server professional with the ability to analyze execution plans, focusing on T-SQL query optimization, by understanding how the execution plan works, how it is created and how to influence the plan as a skeleton key to optimizing T-SQL code.

After presenting the Query Optimizer, we will explore how the execution plans are executed, analyzing the characteristics of key operators, with emphasis on performance.

If you want to dive into to the world of the Query Optimizer, this is the right workshop for you! We’ll have deep dive samples and hours of fun with advanced commands.
