Hi! Let's have a typical schema: Company <- Employee
How can I add a scalar column (in a query or a mapper) to the Company containing the employees count? E.g. query(Company).all() will return list of Company instances and each will have an extra property with emloyees count. But I don't want that retrieved by an extra query for each company. I want that that in one query like "SELECT companies.*, count(employees.*) ...".
