DAX CASE Statement Functionality with IF, SWITCH and SWITCH True
The CASE expression is one of the most valuable tools in your T-SQL toolbox. I use it in almost every query I write. However, there isn't a direct equivalent of CASE in DAX. Since it's a different language entirely, I don't expect it. As my grandmother used to say, I am not surprised, just disappointed. If you don't know, DAX (Data Analysis Expressions) is a language for creating custom calculations and aggregations in Power Pivot, Power BI, and other data analysis tools. Two functions in DAX come close to replicating the functionality but come with limitations. Which one of these functions should you use? Please stay tuned.

Piping, Filtering and Using Flyway Output in PowerShell
Flyway's output is often overwhelmed with verbose messages, most of which we can ignore but some of which provide vital warnings about failed compilations, or useful details about what a migration or callback did. I'll show how to use some pipeline-aware PowerShell functions to filter out and save the bits we want and pass the results along in a form that is useful to the next process in the pipeline.
