I was asked to do a review of the book Microsoft Power BI Performance Best Practices (Amazon link), which means I got a copy for free. The book is written by Thomas Leblanc and Bhavik Merchant and published by Packt. As the title obviously implicates, the book aims to give you a set of best […]

Create a Numbers Table in Power Query
This is a quick blog post, mainly so I have the code available if I need it somewhere in the future 🙂 Sometimes you need a numbers table (also called tally table) when you’re working with data. It’s a table with one single integer column that contains incremental numbers (0,1,2,3,4,…). In a database, it’s fairly […]
Microsoft finally adds Tenant Switcher for Fabric / Power BI
Praise whatever deity you believe in, because it’s finally here, a tenant switcher for Microsoft Fabric (which includes Power BI). A what? Let me explain. When you have a organization with multiple tenants in Azure (also called directories in some products like Azure Devops), or you’re a consultant like me who works with multiple clients […]
Book Review – Humanizing Data Strategy by Tiankai Feng
This book was making its rounds on social media, and the concept seems interesting enough to make me want to read it. It’s a very short book (only 106 pages), but a pleasant read. It focuses on the people side of a data strategy, instead of focusing on technology and tools as sometimes many of […]

Connect to Power BI as a Guest User in another Tenant
Sometimes your Microsoft Entra ID account (formerly known as Azure Active Directory) is added as a guest user in another tenant. This happens quite a lot when you’re a consultant and your client can’t create a new user in their own tenant, so they add the account of your own company as a guest instead. […]
How to use a Script Activity in ADF as a Lookup
In Azure Data Factory (ADF, but also Synapse Pipelines and Fabric Pipelines), you have a typical scenario where you retrieve some metadata from a database and then loop over the metadata with a ForEach activity. For example, to copy all the table from a source database in a metadata-driven pipeline. The obvious choice would be […]
Database Build Error – Incorrect syntax near DISTINCT
I wrote a piece of SQL that had some new T-SQL syntax in it: IS DISTINCT FROM. This predicate checks if two expressions are equal taking NULL into account. I successfully ran the code on an Azure SQL Database. However, when I tried to deploy the code using an Azure Devops pipeline, it returned the […]

My session is about a topic I really love: writing window functions in T-SQL. Tackling the Gaps & Islands Problem with T-SQL Window Functions The gaps & […]
