[User] For each route, show its route number, distance in kilometers, and the total number of trips that have used that route.

[Assistant]
SELECT r.route_number, r.distance_km, COUNT(t.trip_id) AS trip_count
FROM transportation.routes r
LEFT JOIN transportation.trips t ON r.route_id = t.route_id
GROUP BY r.route_number, r.distance_km;

[User] Show me the top 5 tokens by 24-hour trading volume on the Ethereum chain, along with their price and 24-hour price change percentage.

[Assistant] SELECT token_name, token_symbol, price, price_change_percentage_24h, volume_24h FROM token_dexpool_info WHERE chain = 'Ethereum' ORDER BY volume_24h DESC LIMIT 5;

[User] Can you also include the market cap and liquidity for these tokens?

[Assistant] SELECT token_name, token_symbol, price, price_change_percentage_24h, volume_24h, market_cap, liquidity FROM token_dexpool_info WHERE chain = 'Ethereum' ORDER BY volume_24h DESC LIMIT 5;

[User] Show me all policies that expired in the last 60 days, along with their product IDs and premium amounts.

[Assistant] SELECT policy_id, product_id, premium_amount FROM insurance.policies WHERE status = 'expired' AND end_date >= CURRENT_DATE - INTERVAL '60 days' AND end_date <= CURRENT_DATE;

[User] Now include only policies that had a deductible of $1000 or more.

[Assistant] SELECT policy_id, product_id, premium_amount, deductible FROM insurance.policies WHERE status = 'expired' AND end_date >= CURRENT_DATE - INTERVAL '60 days' AND end_date <= CURRENT_DATE AND deductible >= 1000;

[User] I also want to see the count of such expired policies per product ID.

[Assistant] SELECT product_id, COUNT(*) as policy_count FROM insurance.policies WHERE status = 'expired' AND end_date >= CURRENT_DATE - INTERVAL '60 days' AND end_date <= CURRENT_DATE AND deductible >= 1000 GROUP BY product_id ORDER BY policy_count DESC;

[User] Finally, show me the average premium amount for these expired high-deductible policies grouped by product ID.

[Assistant] SELECT product_id, AVG(premium_amount) as avg_premium FROM insurance.policies WHERE status = 'expired' AND end_date >= CURRENT_DATE - INTERVAL '60 days' AND end_date <= CURRENT_DATE AND deductible >= 1000 GROUP BY product_id ORDER BY avg_premium DESC;

[User] List pairs of wallets created on the same day but belonging to different users. Show the wallet IDs, user IDs, and creation dates for both wallets in each pair.

[Assistant] SELECT w1.wallet_id AS wallet1_id, w1.user_id AS user1_id, w1.created_at AS wallet1_created_at, w2.wallet_id AS wallet2_id, w2.user_id AS user2_id, w2.created_at AS wallet2_created_at FROM wallets w1 JOIN wallets w2 ON DATE(w1.created_at) = DATE(w2.created_at) AND w1.user_id != w2.user_id AND w1.wallet_id < w2.wallet_id;

[User] Filter the previous results to only include pairs where both wallet addresses start with '0x'.

[Assistant] SELECT w1.wallet_id AS wallet1_id, w1.user_id AS user1_id, w1.created_at AS wallet1_created_at, w2.wallet_id AS wallet2_id, w2.user_id AS user2_id, w2.created_at AS wallet2_created_at FROM wallets w1 JOIN wallets w2 ON DATE(w1.created_at) = DATE(w2.created_at) AND w1.user_id != w2.user_id AND w1.wallet_id < w2.wallet_id WHERE w1.address LIKE '0x%' AND w2.address LIKE '0x%';

[User] Compute the average and maximum cost of maintenance for each service_type in the maintenance_logs table.

[Assistant]
SELECT service_type,
       AVG(cost) AS avg_cost,
       MAX(cost) AS max_cost
FROM transportation.maintenance_logs
GROUP BY service_type;

[User] Now restrict the result to only those service_type entries where avg_cost > 200.

[Assistant]
SELECT service_type,
       AVG(cost) AS avg_cost,
       MAX(cost) AS max_cost
FROM transportation.maintenance_logs
GROUP BY service_type
HAVING AVG(cost) > 200;
