Category Field Filter not working on Countries and Boolean Fields


I am struggling to get this query working with the filter:

select co.country_name,
from "rails".users u
join "public".countries co
on = 
where 1=1
[[and {{country}}]];

I have mapped the country filter to the “public”.countries, country_name column in the filter widget.

When I do not use the filter I am get the table.

When I do use the filter, say filter for United States of America, I am getting this error:

[Amazon](500310) Invalid operation: invalid reference to FROM-clause entry for table "countries";

I have googled it and the error comes up when the column being referenced is not called in the from clause.

Any help is greatly appreciated.

Thank you!

Hi @VinayakK
Because you cannot use table aliases with Field Filters: - upvote by clicking :+1: on the first post

Hi @flamber,

Thank you very much for the fast reply. I have replaced all table aliases and it works now.
