Two Free Sessions Next Week: Fighting Bad Data and Deadlocks
I am excited and honored to be giving two free online sessions next week. Both events are sponsored by the fine folks over at Quest Software.

I’m proud, giddy, and just plain overly excited to be giving a pre conference session at the SQL PASS Summit in Seattle, Washington on November 5, 2018.
This is going to be a fun, demo-packed day which will teach you skills you can use throughout your career as a developer, database administrator, or data professional.

While features and tricks change from year to year (or even month to month), understanding isolation levels is critical for your long term future.
Are your users seeing bad data? If you’re using the default isolation level of read committed in SQL Server, chances are that sometimes your users get incorrect results. If NOLOCK hints lurk in your code, the odds are even higher that sometimes your customers see information that just isn’t right.
In this day-long, demo packed session, you’ll learn why a single statement may read rows twice, miss rows entirely, or return combinations of data that never existed in the database – and why that’s not a bug. You’ll learn what “read phenomena” are, which isolation levels are vulnerable to them, and the performance trade-offs which come from raising your isolation level to protect your users from bad data.
You’ll see how isolation levels work with newer technologies such as columnstore indexes, In-Memory OLTP, and Always On Availability Groups. You’ll discover why version-based isolation levels can be awesome, and what you need to look out for with these isolation levels to avoid race conditions that produce– you guessed it– incorrect results.
At the end of the day, we’ll pull together all this information into a guide. You’ll leave the seminar with the tools and knowledge to choose the right isolation levels for new and existing applications based on business and performance requirements.
A single pre-conference session is $499. You can also bundle pre-conference sessions with registration at the full Summit.
Attendees at my pre-conference session will not only get all the demos we show live, and a download of the PDF of slides, but also….
Access to a recorded online session of my 8 hour seminar, “Conquer Blocking & Isolation Levels” for a full year.
Want to revisit a topic and get the nitty gritty details? You’ll be able to watch anytime, online.
For four weeks following the conference, I’ll be sending outย SQLChallenges on blocking and isolation level problems.
Want even more learning? Following the SQLChallenges, attendees will get access to a series of four quizzes about blocking and isolation levels to confirm your knowledge.
Combining this with the SQLChallenges will fully establish your new knowledge in place, getting you the most value for your dollar.
I hope to see you at the PASS Summit! Sign up here to join my pre-conference session.
