Reblog: Creating a Semi-additive Measure over a Parent-child Hierarchy

Originally this blog post would be titled “Disabling aggregations over a parent-child hierarchy”, but I thought it could create confusion with the Aggregation Design concept in Analysis Services (SSAS), which is something completely different.

What I want to describe in this blog post is a method forcing a parent-child… Read more

Reblog: What’s the deal with Excel and SSIS?

SQLKover update: When I read this old blog post of mine, all I can think about is: Power Query to the rescue!

How to drop a Temporal Table

No no, I didn’t say temporary, but temporal! SQL Server 2016 introduces a great new feature called Temporal Tables. Or in other words, system-versioned tables. We’ll see what catches on. In a gist, such a table keeps track of the history of its rows by the use… Read more

My first SQL 2016 bug

A little while back SQL Server 2016 CTP2 was announced and I have spent some time playing with it (read: spent hours creating a VM because there were hundreds of Windows updates).
