What's the deal with logins and availability groups? I'm sure that we all, when creating a login that accesses a database that happens to be part of an availability group, diligently go and create that login on all secondary replicas, don't we?!

This is going to be a quick look at an issue that we recently encountered, I'm not going to go in depth into spinlocks and what they are (perhaps that could be the subject of a future post).

In this post I'd like to show you a little something to demonstrate how we can integrate one of these modules... Continue Reading →

So Microsoft have integrated Python into SQL Server, from the moment I heard that I thought to myself, "wow, this is exciting stuff" and not just for the machine learning, BI guys that it was marketed at.
