[User] List all insurance products that have not been updated in the past year. Include product_id, product_name, and updated_at, and order by updated_at ascending.

[Assistant]
SELECT product_id, product_name, updated_at

##Table Structure
CREATE TABLE legal_services.clients ( client_id text, first_name text, last_name text, company_name text, email text, phone text, address text, date_registered timestamp, status text )
CREATE TABLE legal_services.lawyers ( lawyer_id text, first_name text, last_name text, bar_number text, firm_id text, email text, phone text, specialization text, hire_date timestamp, is_partner boolean )

[User] Find all clients and lawyers who share the same phone area code, and show each client's first and last name, each lawyer's first and last name, and the shared area code.

[Assistant] SELECT c.first_name AS client_first_name, c.last_name AS client_last_name, l.first_name AS lawyer_first_name, l.last_name AS lawyer_last_name, SUBSTRING(c.phone, 1, 3) AS area_code FROM legal_services.clients c JOIN legal_services.lawyers l ON SUBSTRING(c.phone, 1, 3) = SUBSTRING(l.phone, 1, 3);

CREATE TABLE blockchain.transactions ( transaction_id text, block_id text, sender_address text, receiver_address text, amount numeric, timestamp timestamp, signature text )
CREATE TABLE blockchain.smart_contracts ( contract_id text, creator_address text, code text, timestamp timestamp )

[User] I want to know how many times each smart contract has been invoked by transactions; also include the contract creator.

[Assistant]
SELECT sc.contract_id, sc.creator_address, COUNT(t.transaction_id) AS invocation_count
FROM blockchain.smart_contracts sc
LEFT JOIN blockchain.transactions t
  ON t.receiver_address = sc.contract_id

[User] I'd like to see only contracts with more than 100 invocations.

[Assistant]
SELECT sc.contract_id, sc.creator_address, COUNT(t.transaction_id) AS invocation_count
FROM blockchain.smart_contracts sc
LEFT JOIN blockchain.transactions t
  ON t.receiver_address = sc.contract_id
GROUP BY sc.contract_id, sc.creator_address
HAVING COUNT(t.transaction_id) > 100;

[User] Actually, I want to order them by invocation_count descending and limit to the top 5.

[Assistant]
SELECT sc.contract_id, sc.creator_address, COUNT(t.transaction_id) AS invocation_count
FROM blockchain.smart_contracts sc
LEFT JOIN blockchain.transactions t
  ON t.receiver_address = sc.contract_id
GROUP BY sc.contract_id, sc.creator_address
HAVING COUNT(t.transaction_id) > 100
ORDER BY invocation_count DESC
LIMIT 5;

[User] Also, show the timestamp when each of those top 5 contracts was created.

[Assistant]
SELECT sc.contract_id, sc.creator_address, sc.timestamp AS creation_time, COUNT(t.transaction_id) AS invocation_count
FROM blockchain.smart_contracts sc
LEFT JOIN blockchain.transactions t
  ON t.receiver_address = sc.contract_id

[User] I need the case_number and case_name along with the total billing amount (hours_spent * billing_rate) for cases that are currently open.

[Assistant]
SELECT c.case_number, c.case_name, SUM(te.hours_spent * te.billing_rate) AS total_billing
