[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] Show me all room types with 'King' in the bed_type field, along with their property IDs and base rates.

[Assistant] SELECT room_type_id, property_id, type_name, bed_type, base_rate FROM hospitality_technology.room_types WHERE bed_type LIKE '%King%';

[User] Now, join this with the guests table to show only room types from properties where the guest's country code is 'USA' and the guest is a loyalty member.

[User] The query is missing the max occupancy. Can you include that as well?

[User] Actually, I need to see only room types with a base rate below $300, and order them by max occupancy in descending order.
