My most recent Quizletter featured a quiz on ORDER BY in TSQL, complete with questions on the OFFSET and FETCH clauses which we got in SQL Server 2012.
One great thing about teaching TSQL School is that it reminds me of these cool options that can be easy to forget.
It’s been a fun, busy spring and early summer. I have loads of new courses to share, and great stuff is coming up soon!
A big thank you to all the SQLWorkbooks members who attended live events, or posted your comments and questions! Your questions are terrific, and you’ve made these events so much fun.
This week’s Quizletter featured a quiz on using the AVG() function in SQL Server.
I was inspired to write this quiz because I’ve been teaching “TSQL School” each week. When we covered aggregate functions, I remembered how tricksy AVG() can be.

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.
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. Why is That Data Wrong? How Choosing the Wrong Isolation Level Causes Bad Results Tuesday, June 12, Noon Pacific 24 Hours of PASS, Sponsored by Quest Software If you haven’t thought much about isolation levels in SQL Server, chances are your applications can return inconsistent data to your users: data that looks completely wrong.
A question came up in my webcast today on the topic of Snapshot and Read Committed Snapshot Isolation - what impact will enabling these have on my SQL Server instance?
This question came up in a webcast recently: if a filtered index is causing data modifications to fail, does disabling the filtered index fix the problem?
DBA vs Deadlock: How to Out-Index a Deadly Blocking Scenario June 14, 2018 8:30 AM – 9:30 AM PST <- This is past, but no worries, it was recorded Deadlocks strike fear into the hearts of even seasoned DBAs — but they don’t have to! In this session, you’ll get the code to cause a sample deadlock in SQL Server. You’ll see how to interpret the deadlock graph to find out where the conflict lies, and how to design an index to make the deadlock disappear.
I got a question recently about why a particular bit of code was failing when running.
