This month’s #tsql2sday is hosted by John McCormack who asks us to share some useful snippets of code that can help us in our everyday jobs.
Well, honestly, this is more or less what my blog is mostly about anyway: sharing insights, scripts, and code snippets that I found to be helpful in my day-to-day job as a SQL Server consultant.

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.

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.

If you know me, you already know that I’m a huge fan of automation. Therefore, it’s natural to assume that I would dabble in Powershell at least once or twice or a few dozen, as a method to implement useful automations. After all, automation is pretty much the whole essence of Powershell in the first place.
As I used Powershell scripts more and more, I learned that there are a few things that are important to have whenever you use such scripts as part of automation (by “automation” I mean any sort of operation done “unattended”, i.e. without direct human interaction in real-time).

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.

Sometimes SentryOne would not be able to activate its “Full Access” monitoring mode. This article describes a simple but effective methodology to resolve such issues.
As part of its regular, ongoing, day-to-day activities, your SQL Server instance would naturally collect historical data about its automated operations. If left unchecked, this historical data could pile up, leading to wasted storage space, performance hits, and even worse issues.
MSDB would obviously be collecting data about the SQL Agent job executions. But there are also several other types of historical data that needs to be cleaned up once in a while. I hope to cover all bases and leave no historical data un-cleaned.
