DAX for Power BI videos | DAX for Power BI Part 2.4 - Working with Blanks

Posted by Andrew Gould on 21 August 2021

This video shows you how to work with blanks in your DAX expressions for calculated columns. You'll learn you to test for blanks using the IsBlank function and the Blank function. You'll see the difference between the equal to and strictly equal to operators and the importance of that difference when it comes to working with blanks. You'll learn how to produce a blank as the result of an expression and what happens when you involve a blank in some basic arithmetic. Finally, you'll see how to concatenate a blank into a string and how to use the Coalesce function to produce a replacement value.
