CREATE TABLE healthcare.insurance_plans ( plan_id text, plan_name text, insurance_provider text, plan_type text, contact_phone text, website text )

[User] I want to list all insurance plans along with the number of medical records that have a record_date in 2024. Display plan_id, plan_name, and the total medical records.

[Assistant]
SELECT ip.plan_id, ip.plan_name, COUNT(mr.record_id) AS total_medical_records
FROM healthcare.insurance_plans ip
LEFT JOIN healthcare.medical_records mr ON 1=0 -- there is no direct relationship in schema, so no records will be counted
WHERE mr.record_date >= '2024-01-01' AND mr.record_date < '2025-01-01'
GROUP BY ip.plan_id, ip.plan_name;

[User] Since there's no direct relationship, can you adjust it to just show all insurance plans of type 'EPO' with their plan_id and plan_name?

[Assistant]
SELECT plan_id, plan_name
FROM healthcare.insurance_plans
WHERE plan_type = 'EPO';

[User] What is the current number of passengers at station with ID 'ST123' right now?

[Assistant] I'm sorry, but I can't provide information on the current number of passengers at a station. The data I have access to only includes static details about stations such as their name, location, and number of platforms, not real-time passenger counts.
