[Assistant] SELECT c.first_name, c.last_name, COUNT(a.appointment_id) AS scheduled_appointment_count FROM government_services.citizens AS c JOIN government_services.appointments AS a ON c.citizen_id = a.citizen_id WHERE a.status = 'Scheduled' GROUP BY c.citizen_id, c.first_name, c.last_name;

[User] I got an error with that query. Let's simplify. Just show the first name, last name, and the total number of all appointments (regardless of status) for each citizen.

[Assistant] SELECT c.first_name, c.last_name, COUNT(a.appointment_id) AS total_appointment_count FROM government_services.citizens AS c JOIN government_services.appointments AS a ON c.citizen_id = a.citizen_id GROUP BY c.citizen_id, c.first_name, c.last_name;
