This class's recordings will be available after the first live Fundamentals Week class finishes on July 17.

2026-07-16: First live class rotation for 2026! Lots of changes:

• "How SQL Server Builds Query Plans" chapter - remixed from a combination of Fundamentals & Mastering material.
• "Good Defaults for New Apps" chapter - all new
• "Tools to Improve Cardinality Estimation" chapter - remixed from a combination of Fundamentals & Mastering material.
• "Lab - Improve Cardinality Estimation" chapter - adapted from a former Mastering Query Tuning lab.

Even if you've been through Fundamentals of Query Tuning before in prior years, you're going to want to restart this one from scratch.
