[User] How many medications are listed per manufacturer? Return manufacturer and med_count for those with more than 10 medications.

[Assistant]
SELECT manufacturer, COUNT(*) AS med_count
FROM healthcare.medications
GROUP BY manufacturer
HAVING COUNT(*) > 10;

[User] Now sort these by med_count in descending order.

[Assistant]
SELECT manufacturer, COUNT(*) AS med_count
FROM healthcare.medications
GROUP BY manufacturer
HAVING COUNT(*) > 10
ORDER BY med_count DESC;

[User] Retrieve trip_id and passenger full names for all trips where the passenger record was created before the scheduled departure.

[Assistant]
SELECT t.trip_id, p.first_name || ' ' || p.last_name AS passenger_name

[User] I need the average capacity of vehicles for each fuel_type.

[Assistant]
SELECT fuel_type,
