Some time ago I was writing some windowing functions on a set of data. Basically I was looking for the last date an event had occurred for each type of event. Let’s illustrate with an example: CREATE TABLE dbo.TestOver (ID INT IDENTITY(1,1) PRIMARY KEY NOT NULL ,[Group] CHAR(1) NOT NULL ,Value INT NOT NULL); INSERT […]

SQL Server Days 2014 is over, but it has been one great event. A very big thanks to the organizers! My session went pretty well, somewhere around 60 attendees I would guess and they didn’t seem too bored. I saw some other great sessions as well, such as Buck Woody (twitter) on Big Data (and […]
Lately I have been using more and more the awesomeness of the Alt-button in SQL Server Management Studio (SSMS). What do I mean with this? While holding the Alt-button on your keyboard, you can select a block of text instead of lines of text. Note that this is not an exclusive feature, you can do […]
SQL Server Management Studio (SSMS) has a lot of cool little tips and tricks. Last night, while presenting for 24 Hours of PASS, I used the Window Split function and noticed a few “oohs” and “aaahs” on Twitter. Here’s how you do it. Open a query in SSMS. In this case, I was looking at […]

This post contains all of the steps, software, and scripts that […]
After quite a while it has finally returned: another Stupid Me™®©! A reminder: Every time I do something “stupid”, which happens from time to time, I’ll do a little blog post on what happened and how I solved it. The reason for this is twofold: I’ll have a solution online I can consult if it […]

The book is published by Packt but I am relieved to say this time there were no significant editing issues. In fact it is quite well written and as far as I could tell […]
A few months ago I followed an introductory course about the data vault modeling technique for data warehouses at a local training provider. As part of the training, I received the book Modeling the Agile Data Warehouse with Data Vault written by Hans Hultgren who also is an instructor for the official data vault certification. […]
With “Matrix Infographic” I simply mean those infographics FiveThirtyEight (site | Twitter), the website of statistic revelation Nate Silver, uses to display forecasts of World cup matches. An example: I was wondering if something similar could be built using SSRS. And yes, it is possible and it isn’t that hard. My starting point is a […]
ITPROceed 2014 is now a thing of the past, but is has been an awesome – and free! – event. A very big thank you and “well done” to the organizers. It has been a great gathering of the #sqlfamily, with superb sessions about Azure, restoring databases with PowerShell, Hekaton (yes yes In-Memory OLTP), Administration […]
