Count records where two fields have distinct values

Question

Good afternoon,

I am looking for a way to  count in a layer how many records have two fields distinct, and show  the result in a text box.

Thanks

Hi @SanchezNuñez ,

The text widget supports Arcade expressions in the June 2025 AGOL release.

You can use a script like this in your expression:

var ds = $dataSources["dataSource_id"].layer;
var distinctItem = Distinct(ds, 'CNTRY_NAME');

return Count(distinctItem);

Regards,

This is what I need if I use a SQL Statement:

SELECT distinct
[ProjectNumber]
,[ProjectPage]
FROM ProjecTables

And the count will be

SELECT COUNT(*)
FROM (
SELECT distinct
[ProjectNumber]
,[ProjectPage]
FROM ProjecTables
) as dt

Please advise
