This month’s T-SQL Tuesday is hosted by Deb the DBA (b|t), who invites us to give a long rant about a question that a coworker could be asking us, without knowing what they’ve just gotten themselves into by doing that.
Well… I’ve got just the thing 🤭

Following the rise in popularity of DevOps for Databases, many interesting questions are being asked on the topic.
One of these questions is: Should your SQL Database project be in the same source control repository and solution as the App code project? Or maybe they should be in the same repository but separate solutions? Or maybe they should be in completely separate repositories?

Who doesn’t like Filtered Indexes, am I right? They’re pretty great, honestly. If… of course… you’re able to actually create them and utilize them in your specific use cases. That… unfortunately, could often become a complicated, if near impossible, task. So, what if our use case is not trivial enough to allow for filtered indexes?

“Extended properties allow you to add custom properties to database objects”, so says the official Microsoft documentation. However, very few DBAs make use of them, if at all. This is actually a good thing, because indeed the scenarios in which this feature could be useful are relatively few and rare.
On the other hand, I also see DBAs essentially jumping through hoops to implement something, which could in fact very easily be implemented using Extended Properties.
What are these peculiar use cases? Let’s look at a few examples.

Do you find yourself facing performance problems and long lock chains caused by very frequent INSERT, UPDATE, or DELETE statements being executed on a table? Check out this neat trick that could help you out and make all the difference in the world.

In one of my previous posts, Fun with DATETIME Arithmetics, I introduced a way to use “math” to manipulate datetime values for effectively generating, calculating, and displaying intervals (i.e. difference between two datetime values). These mostly work with the addition and subtraction operators (+, -).
In one of the paragraphs, I mentioned multiplication and division, and posed the question about why anyone would ever need to do this.

Did you know that we can have basic datetime arithmetics in SQL server? We can use subtraction to find an accurate difference between two dates, and use addition to add an accurate interval to a datetime column or variable.

This month’s T-SQL Tuesday is hosted by Brent Ozar, who asks us to Blog about our Favorite Data Type (or Least Favorite).
I find it actually quite easy to decide both on a most-favorite, as well as a least-favorite data type in SQL Server. So, why not blog about both?
This is one of those things that I would have never expected to adopt, and yet here I am! Not just loving “infinite” loops, but also confident enough that I can convince you to feel the same!
