Boolean Aggregate Functions?

MarkEvansHW — Fri, 11 Sep 2020 11:48:02 GMT

Is there any way to aggregate a boolean field so that the summary result with be TRUE if any of the detail rows are TRUE? Similarly, aggregate so that the summary result is TRUE if all of the detail rows are TRUE?

In postgresql and Redshift, these aggregating functions are named bool_or() and bool_and() - they are very handy at times. Does anyone know how to accomplish the same thing within Power BI? Thanks.

MarkEvansHW , Not very clear. But I doubt I noticed aggregating functions. Can you share sample data and sample output in table format? Or a sample pbix after removing sensitive data.

MarkEvansHW Yes, this works:

Measure 5 = IF(TRUE() IN SELECTCOLUMNS('Table (5)',"Column",[Column1]),TRUE(),FALSE())

PBIX is attached below sig

To check if any TRUE exists in a field use this measure:

AnyTRUE = CONTAINS(Table,Table[Column],TRUE())

To check if TRUE exists in all rows of a field, use this measure:

AllTRUE = NOT CONTAINS(Table,Table[Column],FALSE())
