Whee! It’s the first day of the main SQL PASS Summit conference and I made it to the keynote early for the first time ever. The hype says we’re going to see some great presenters this morning.
One of the great things about writing presentations is that it spurs you to “clean up” your definitions. When it comes to writing a slide about something, I ask myself, “Do I really know what that is?” I check my assumptions, and clarify how I think about something.
This week I was working with SQL Server memory settings, and I “cleaned up” my understanding of the following definitions.
PASS Summit sessions have been scheduled, and I’m excited to be giving two sessions this year AND helping judge Speaker Idol!
I’m looking forward to teaching, learning a ton, and connecting with lots of people who love working with data.
SQL Server Service Packs are going away, starting with SQL Server 2017. I talk about why I think this is a good thing, and discuss Cumulative Updates, Service Packs, and the process of updating SQL Server.
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.
