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 🤭

A few years ago, I created a couple of T-SQL scripts that can be used for comparing instance-level and database-level properties between two HA/DR replicas. Originally, this supported comparing only two servers. But recently, following a fan request, I upgraded the script to support an unlimited number of servers that you can compare to each other.
So, I figured, if one person found this useful, there must be more out there that would need this, right?

Turns out there’s a shortage of solutions online for easily managing partitioned tables in SQL Server. Well… I guess I’ll have to do it myself!
This is a T-SQL script that I’m cross-publishing with the official Madeira Data Solutions blog.
This script generates various permutations and variations of common and weak passwords and uses the PWDCOMPARE function to check whether there are any enabled SQL logins that have these passwords.

Which drawbacks are there to using the built-in sp_MSforeachdb stored procedure? What other alternatives are out there? Is there a simpler solution? Find out all this and more in this short post.

“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.

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.

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?
