Mastering Query Tuning

You need to speed up a SQL Server app, and you’re allowed to change the queries and indexes – but not the server hardware or settings. Good news – I’ll teach you how in 3 days of learning and fun. Join me, Brent Ozar, as I explain how to make your SQL Server apps go faster.

Labs & lectures include:

• How SQL Server builds query plans
• How to find the queries you need to focus on first so end users will notice an improvement
• How to choose between CTEs, temp tables, and APPLY
• How to tune for SELECT * and lots of rows
• How to write dynamic SQL that scales
• How to avoid pitfalls like deadlocks and bad batching
• How SQL Server 2017 & 2019’s new robots help (and hurt)
