Does anyone know if there is a way to create a sentence similar to this one:
return this.db.collection('places', ref => ref.where("CodPais", "<>", pais)).valueChanges();
I have tried using != and <> but neither seem to be valid. Is there another method that can be used?
When using the where() method, you will need to provide three parameters: a field for filtering, a comparison operation, and a specific value. The available comparison operators include <, <=, ==, >, or >=. iOS, Android, and Java require you to explicitly specify the comparison operator within the method.
