Democratizing Self Service Cloud Analytics and ELT Supporting Modern Cloud Data Management Approaches

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.

Detecting Characters

I have a SQL Server 2022 English default installation on a server. I want to detect if there are any upper case characters in rows and I have this code:

SELECT CustomerNameID,
       CustomerName
 FROM dbo.CustomerName
 WHERE CustomerName = LOWER(CustomerName)
Here is the sample data I am testing with:
CustomerNameID CustomerName
1              John Smith
2              Sarah Johnson
3              MICHAEL WILLIAMS
4              JENNIFER BROWN
5              david jones
6              emily davis
7              Robert Miller
8              LISA WILSON
9              christopher moore
10             Amanda Taylor
How many rows are returned?
