calculated column doesn't show blanks

[Anonymous]

I have a column in the dataset (Query), which has 3 values: 1, 0 and null.

When creating visualizations, I figured I need a different representation of that column. So, I created a Calculated Column:

CalcCol = IF(Col1 = 1, "Yes", IF( Col1 = 0, "No", Blank()))

But I see only Yes, No values in the new calculated column. I don't see Blanks at all. I think they are combined with No.

However, if I crate a Custom column in Edit Queries window to achieve the same, I get all three values.

I want to understand why this is the case and would really like to have the calculated column work the desired way, instead of having to create Custom column in edit queries (where it means refreshing the entire dataset and is clumsy given I have lot of huge queries).

Hi @Anonymous,

I have asked the Product Group and they replied that: "In DAX, the comparison operator = performs equivalence comparison. Since 0 and BLANK are equivalent values, operator = returns true when comparing 0 to BLANK. Users can use DAX function IsBlank to detect BLANK values. "

Hope it could help you.

Thanks Daniel. This is really helpful. It's just that "Column from Examples" in Edit Queries, works differently. 🙂
