Cool Stuff in Snowflake – Part 14: Asynchronous Execution of SQL Statements
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. It might be some SQL function that I’d really like to be in SQL Server, it might be something else. It’s been a while since I […]
Free webinar – Tackling the Gaps and Islands Problem with T-SQL Window Functions
I’m hosting a free webinar at MSSQLTips.com at the 19th of December 2024, 6PM UTC. The topic is about window functions, something that really interests me and that should be in the toolbox of every season SQL developer. The abstract: The gaps and islands problem is a common problem in data analysis. Some examples are: […]
System Views in Microsoft Fabric – Query references an object that is not supported in distributed processing mode
I have a metadata-driven ELT framework that heavily relies on dynamic SQL to generate SQL statements that load data from views into a respective fact or dimension. Such a task is well suited for generation, since the pattern to load a type 1 SCD, type 2 SCD or a fact table is always the same. […]

Get your Query History in Redshift
Because my Windows machine apparently decides to install updates over night (and thus reboot my machine), it has happened that I lost the query that I was writing for Redshift in the tool DBeaver. When you work with SQL Server Management Studio (SSMS), you typically don’t have this issue as a temporary copy is always […]

Why Managed Identities are Awesome
For the first workdays of this new year, I had the pleasurable task of resetting a bunch of passwords. The passwords belong to Azure AD users, service principals, SQL Server users etc. and all of these are tied into the ETL process of a data warehouse. Some are used to connect to source data, others […]

The nice people from Packt Publishing sent me a digital copy of Benjamin Nevarez new book to review: SQL Server Query Tuning and Optimization – Optimize Microsoft SQL Server 2022 queries and applications. It says first edition on the cover, but that’s because it’s the first time this book has been published by Packt. The […]
