Read this before using SQL 2016 Temporal Tables
I’ve been testing the new Temporal Tables feature over the past day to see about using it in one of our production databases. It’s a neat feature that honestly adds a boat load of possibility around logging.
In my testing I noticed that user created tables seem to store the rows over quite a bit more pages. User created history tables were nearly double the size of an auto generated one. If you’re currently using the feature or plan to use it in the near future, you’ll want to think about this storage issue before you implement.
A quick note comparing ISNULL vs COALESCE
There are hundreds of blogs that compare the T-SQL ISNULL function with the ANSI standard COALESCE function. There are also plenty of arguments of why you should use one over the other.
Understanding the new MAXDOP settings in SQL 2016
If you have just begun using SQL Server 2016 or you have been using it for a while now you may not have noticed the new MAXDOP settings.
Splitting CSV strings in SQL 2016

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.

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.

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.
