WARNING: do not do this in production. A quick blog post on a SSMS trick: how to quickly edit data. Sometimes you directly want to manipulate data without having to write a SQL statement. For example, in the development environment you want to modify a value in a column to test out a scenario, or […]
SUMX returns incorrect results with duplicates

Let’s dive into the issue with an example. The Problem Suppose we have employees entering timesheet data. An employee can work on multiple projects in […]
Cool Stuff in Snowflake – Part 11: RESULT_SCAN
I’m doing a little series on some of the nice features/capabilities in Snowflake (the cloud data warehouse). In each part, I’ll highlight something that I think it’s interesting enough to share.

Cloudbrew 2019 – Slides
Cloudbrew 2019 is over and it was a great event. Great speakers and a big audience. Even in my session there were a lot of attendees, which I found a bit surprising, because at general tech events there tend to be less people in the data tracks. Not this time however, I nicely filled room […]

It’s T-SQL Tuesday time again! This edition is hosted by Malathi (blog|twitter) and the subject is looking back at the past year. So what do I have to be thankful for?

Restarting SQL Server after adding a new SQL login
At a project, we asked if we could get a SQL Server login/user so we could make a connection from an Apache Airflow pipeline to the SQL Server instance. The answer was: “No, because then we would need to restart the server”. This sounded a bit strange, because I’ve never had to restart the SQL […]
