When should I use a CTE?
If I had a dollar for every CTE solution to a simple query in the forums (pick any SQL forum), I’d be Mark Cuban. With that said I thought it would be a good idea to ask if a CTE was actually the right solution or if it’s just the new trend and everyone uses them just because they can and all the cool kids are too. Let’s put it this way: If I had a dollar for every time a CTE was misused, I’d be Mark Cuban… or at least Robert Herjavec.
I’m speaking at SQL Saturday 563 in Dallas
This will be my second time speaking at SQL Saturday in Dallas. My first was last year and it was a great time. I enjoyed hanging out with all the attendees and speakers. Who wouldn’t want to have a chat with Kalen Delaney or Bob Ward? The Dallas edition of SQL Saturday is on 9/24 in Arlington at the University of Texas. Be sure to set the date I’m sure this will be a lot of fun and there will be plenty to learn!
My session is A DBA’s guide to whole stack performance troubleshooting. You’ll want to check this out.

Using PowerShell to find Processor issues & more
One of the top three performance killers for SQL Server is lack of processing power. I’d say that it’s second only to storage latency and more of a concern than memory. Although with anything in SQL we can say it depends.
Inside the mind of a c# developer
I’ve been working with SQL Server for 18 years and over that long span I’ve seen a lot of different techniques for tuning and development.
There are essentially two principles of development, Code First and Database First. Naturally, being a life long database professional I’d say that Database First is the only way to properly approach a project. You’d start with a business analyst gathering requirements, build out the database ERD, and then start coding.
SQL Server 2016 FK operator bug?
I recently read an a blog on MSDN that covered new features for the query optimizer in SQL Server 2016. One of the topics covered was a new operator for foreign key checks.
This new operator certainly looked like it simplified the graphical plan considerably; so, I thought I’d test it out. Here’s what I found:
Off topic–Would you SQL your license plate?
I was recently browsing www.myplates.com and I’ll say it’s actually quite fun to see what plates people have randomly bought. I found it easy to spend 15 or so minutes typing in all sorts of fun and silly things into the search just to see what would come up.
Retrieving diagnostic data from SQL Server’s Default Trace
Have you ever tried to query the contents of the default trace and then spent more time trying to figure out the name of the oldest file than the actually analyzing the data?
Azure SQL Database waits you should be aware of…
I’ve been using Microsoft’s cloud database for some time now. I’ve had a few customers with various performance problems and thought I’d take a moment to highlight the interesting behavior you may run into as well.
