My previous post on load testing Azure SQL covered the General Purpose Edition, let's move it up to the Business Critical Tier The Business Critical tier comes in two flavours: General and confidential compute. For my testing, I've stuck with the General SKU. I haven't seen confidential compute with customers, and it has very specific … Continue reading Load testing SQL: the sequel. Let’s get Business Critical!
My previous post on load testing Azure SQL covered the Premium Edition; today I'm moving to the General Purpose Tier. The GP tier comes in two flavours: regular and serverless. Serverless has only one hardware tier: Gen5. With provisioned, you can also select memory-optimised or confidential compute. In earlier tests, I never found significant differences … Continue reading Load Testing SQL: The sequel. General Purpose Edition
My previous post on load testing Azure SQL covered the Standard Edition; today I'm moving to the Premium Edition, which is Business Critical in DTU shape. Again, the calculation mixes CPU, Memory, and disk I/O. The main difference between Standard and Premium is cost. Premium is more expensive and aimed at mission-critical workloads. It has … Continue reading Loadtesting SQL: The Sequel: Premium Edition

Day 0: the MVP day On Monday, you have three options, depending on your relationship … Continue reading Microsoft Fabric and SQL Community Conference 2026, the Barcelona edition
I was trying out some things to learn more about RegEx when I ran into something weird. When using REGEX_LIKE in a query, I got an error in both SQL Server and Azure SQL Hyperscale. Now, I learned what will be shared in this blog from Cláudio Silva, Greg Low, and Erland Sommarskog. They were … Continue reading SQL Server REGEX_LIKE confusion

Because I had to learn how JSON works in SQL Server for my DP-800 exam, I decided to see how the JSON index works … Continue reading SQL Server 2025: Testing the JSON Index
When you start using SSMS with GitHub Copilot, there is no default set of instructions in place. The agent will just sort of do what it thinks is best. But you can make sure the agent has more knowledge of your local environment (yes, it can be a cloud database as well), how it should … Continue reading SSMS 22.6: Custom Copilot instructions
This month, Koen Verbeeck invites the blogging community to write about their thoughts on returning to on-premises. What could be struggles, things we have to re-learn, etcetera. When I read the invite, it immediately sparked inspiration, because there are increasing rumours around cloud exits. People musing about 'what if'. Some clients reference these questions, but … Continue reading T-SQL Tuesday #199: Back to on-prem?
The DP-800 training is new and was released to GA a few weeks ago. It now sits in the same family as DP-600 (Data Analytics using Microsoft Fabric), 700 (Data Engineering using Microsoft Fabric) and 750 (Data Engineering using Databricks). The full name of this training is "Develop AI-Enabled Database Solutions". This one sparked my … Continue reading DP-800: First Microsoft Learn experiences
Maybe you've read my blog post in the DP-700 certification series about mirroring data. You can find that one here. This blog will be longer and more technical. And involve SQL Server. To make reading a little easier, I've listed the Microsoft Learn pages at the end of this blog post. While writing the DP-700 … Continue reading Mirroring SQL Server 2025 to Microsoft Fabric, a level deeper
