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!

Following an incident at a customer’s production environment, Nathan Lifshes and I realized that we stumbled upon a yet-unknown bug in SQL Server, causing an access violation error, memory dumps, dropped connections, and even cluster fail-overs.

This month’s #tsql2sday came to us from Rob Volk (b|t), who asks us to explain databases using an analogy, as if explaining to a 5 year old. I’m actually a big fan of The Feynman Technique (aka ELI5), so I really wanted to participate. But to be honest, I nearly missed out this time simply because I couldn’t think of an idea this whole week.
On the very last day, when the posts already started rolling out by all the bloggers, I’ve read a few, and only then the muse finally hit me. I kid you not, the time is literally 23:59 here in Israel as I hit the publish button!
So anyways, the idea I had was for the ALTER TABLE..SWITCH TO command in SQL Server.

On June 3rd, the InfosecMatter blog published a post titled “Top #10 Vulnerabilities: Internal Infrastructure Pentest“. This blog post detailed the top most common vulnerabilities in Windows servers and networks found during more than 60 internal infrastructure penetration tests around the world. After reading this article, I was prompted to actively look for similar resources on SQL Server penetration testing, and I got some interesting findings. Check out my blog post at the Madeira Data Solutions website for the details.

You might have seen this blog post by Paul White: New Metadata-Only Column Changes in SQL Server 2016. It talks about how, when a table is compressed, you can change (i.e. increase) a column’s data type without having to create a new table and migrate the data into it, and without having to refactor all of the underlying data. But, not everything is rainbows and unicorns…

The #DataWeekender is a free online conference scheduled for May 2nd, organized by the SQL Server community’s finest, as an online replacement for all the SQL Saturdays and other SQL Server conferences that were being canceled en masse due to the COVID-19 situation.
One of my submitted sessions was accepted:

Its high importance and value should be a no-brainer. But it can be a very difficult topic, and the hardest thing about it, in my opinion, is knowing where to start. Hopefully, with this blog post, I can help you out with that.

Watch now! In this session, the second of a 2-part series, we will cover the rich tools, features, and methodologies in SSDT that allow DBAs to implement a continuous database development lifecycle, and how to solve common problems and edge cases.
This webinar was delivered as part of the PASS Global Hebrew Virtual Chapter, and as such is presented in Hebrew.
Watch now! In this session, the first of a 2-part series, we will learn what is Git Source Control? What are CI/CD Pipelines? What are Unit Tests? These are all topics that each DBA must familiarize themselves with before integrating with the software development lifecycle.
This webinar was delivered as part of the PASS Global Hebrew Virtual Chapter, and as such is presented in Hebrew.
A lot of DBAs would spend hours (and even days) sitting in front of their computer to write a stupendous amount of lines of code… Then take care of a lot of copy-paste and typing errors… Test the code and find errors… Fix the code… Run it again… And so on. All the while having to navigate within a huge forest of code.
I would presume that it doesn’t take a special kind of mind to stand up and say “just hold on a minute! Why am I working so hard with this mundane task?? Why can’t SQL Server do all of this for me??”
Because in fact… It can!
