DAX for Power BI videos | DAX for Power BI Part 4.3 - Counting Values and Rows

Posted by Andrew Gould on 26 November 2021

This video shows you a variety of ways to count things in DAX. You'll learn how to count values in a column using the COUNT and COUNTA functions, and what effect blanks have on the result of the count. You'll see how to use the COUNTROWS function to avoid issues caused by blanks and how to count unique values using the DISTINCTCOUNT and DISTINCTCOUNTNOBLANK functions. Finally, you'll learn how to count the result of an expression using the COUNTX and COUNTAX functions, as well as how to combine these with the IF function to create a rudimentary CountIf setup.
