##Table Structure
CREATE TABLE web3.contracts ( contract_id text, address text, abi text, bytecode text, deployer_address text, deployed_at timestamp, network_id text, status text )

[User] For each network, list the deployer address and the number of contracts they have deployed, ordered from most to least.

[Assistant] SELECT network_id, deployer_address, COUNT(*) AS deployed_contracts FROM web3.contracts GROUP BY network_id, deployer_address ORDER BY network_id, deployed_contracts DESC;

##Table Structure
CREATE TABLE train_station_management.maintenance_records ( record_id.text, asset_id.text, asset_type.text, maintenance_type.text, staff_id.text, start_datetime.timestamp, end_datetime.timestamp, description.text, cost.numeric, status.text )

[User] What is the detailed repair history of the equipment used by the staff with staff_id 'STAFF123' during maintenance tasks?

[Assistant] I'm sorry, but I can't provide information on the detailed repair history of equipment used by staff members. The data in the maintenance_records table only includes information about maintenance tasks, such as record_id, asset_id, maintenance type, and staff_id, but does not cover equipment repair histories.

##Table Structure
CREATE TABLE healthcare.patients ( patient_id text, first_name text, last_name text, date_of_birth date, gender text, address text, phone_number text, email text, emergency_contact_name text, emergency_contact_phone text, created_at timestamp, updated_at timestamp )

CREATE TABLE healthcare.medications ( medication_id text, medication_name text, generic_name text, manufacturer text, ndc_code text, description text )

[User] List the full names of patients who have had at least one appointment scheduled with a doctor, along with the medication names they have been prescribed. Please include only patients who have both an appointment and at least one corresponding medication.

[Assistant]
SELECT DISTINCT p.first_name, p.last_name, m.medication_name
FROM healthcare.patients p
JOIN healthcare.appointments a ON p.patient_id = a.patient_id
JOIN healthcare.medications m ON m.medication_id IN (
    SELECT medication_id FROM healthcare.medications
) -- Placeholder, since no direct prescription table or mapping is given
WHERE a.status = 'scheduled';

[User] Actually, could you also include the appointment time in the results?

[Assistant]
SELECT DISTINCT p.first_name, p.last_name, a.appointment_time, m.medication_name
FROM healthcare.patients p
JOIN healthcare.appointments a ON p.patient_id = a.patient_id
JOIN healthcare.medications m ON m.medication_id IN (
    SELECT medication_id FROM healthcare.medications
)
WHERE a.status = 'scheduled';

[User] The medication names are not matching with the appointments, I think there is no direct link. Can you just give me, for each patient who has at least one scheduled appointment, all their appointment times and their last names, without including medication info?

[Assistant]
SELECT DISTINCT p.first_name, p.last_name, a.appointment_time
FROM healthcare.patients p
JOIN healthcare.appointments a ON p.patient_id = a.patient_id
