I received a question recently asking about disk access patterns for index seeks in SQL Server. The question suggested that index seeks would have a random read pattern.
Is this necessarily the case?
People have strong feelings about SQL Server Management Studio: they love it AND they hate it. In this week’s episode, I talk about why people have such conflicting feelings about SSMS, and how to work it all out.

A query is slow, and you figure out how to collect the query execution plan. Now what?
In this video, I talk “big picture” about what execution plans are, what “cost” is, why to collect “compiled for” values, and the steps I take to analyze execution plans while performance tuning queries.
I came across a fun deadlock when writing demos for my session on the Read Committed isolation level this week. (It’s OK to call it “fun” when it’s not production code, right?)
I was playing around with a nonclustered columnstore index on a disk-based table. Here’s what I was doing:
As a SQL Server DBA, do you need to be a master of PowerShell scripts?
In this 9 minute episode, I talk about how much you need to know about PowerShell, and examples of ways I personally use (and struggle with) PowerShell.
Last week, I had a great time giving a webcast for the terrific DBA Fundamentals Virtual Chapter. If you like free online training, check them out and sign up for future events.
I’ll be attending and presenting at the SQL PASS Summit in Seattle Washington this year from Oct 31-Nov 3. In this week’s 19 minute episode, I share why I’m excited about going and why I’ve purchased a seat for a pre-conference session. I also give my tips on how to get the most value out of a big conference like the PASS Summit.
I like to use the keyboard whenever I can in SQL Server Management Studio. It’s not always easy to remember every shortcut though– especially when those shortcuts change!

Over the years, readers have asked me: “How do you stay motivated?” Sticking with a learning plan, blogging, or becoming a public speaker isn’t easy.
In this 15 minute episode, I share how I think about motivation and what keeps me going.
