[User] List all depot locations in the United States with their city and state information.

[Assistant] SELECT name, city, state_province FROM transportation.locations WHERE type = 'depot' AND country = 'United States';

[User] Can you include the full address and order by state_province first, then by city?

[Assistant] SELECT name, address_line1, city, state_province, postal_code FROM transportation.locations WHERE type = 'depot' AND country = 'United States' ORDER BY state_province, city;

[User] Now filter to only show depots in Texas or California and include their timezone.

[Assistant] SELECT name, address_line1, city, state_province, postal_code, timezone FROM transportation.locations WHERE type = 'depot' AND country = 'United States' AND state_province IN ('Texas', 'California') ORDER BY state_province, city;

[User] Actually, I need to see the latitude and longitude as well and limit to 5 results per state.

[Assistant] SELECT name, city, state_province, latitude, longitude FROM transportation.locations WHERE type = 'depot' AND country = 'United States' AND state_province IN ('Texas', 'California') ORDER BY state_province, city LIMIT 5;

[User] List all assets that have been traded at least 50 times, along with their total trade volume (quantity * price).

[Assistant] SELECT asset_id, COUNT(*) AS trade_count, SUM(quantity * price) AS total_volume FROM trading_platform.trades GROUP BY asset_id HAVING COUNT(*) >= 50;

[User] Now filter these results to only show assets where the average trade price is above 100.

[Assistant] SELECT asset_id, COUNT(*) AS trade_count, SUM(quantity * price) AS total_volume, AVG(price) AS avg_price FROM trading_platform.trades GROUP BY asset_id HAVING COUNT(*) >= 50 AND AVG(price) > 100;

[User] Can you modify the query to also show the most recent trade timestamp for each asset?

[Assistant] SELECT asset_id, COUNT(*) AS trade_count, SUM(quantity * price) AS total_volume, AVG(price) AS avg_price, MAX(traded_at) AS last_trade FROM trading_platform.trades GROUP BY asset_id HAVING COUNT(*) >= 50 AND AVG(price) > 100;

[User] Could you provide the total number of game sessions and the number of distinct players for each game genre? Display the genre, session count, and player count.

[Assistant] SELECT g.genre, COUNT(gs.session_id) AS session_count, COUNT(DISTINCT gs.player_id) AS player_count FROM gaming_technology.game_sessions AS gs JOIN gaming_technology.games AS g ON gs.game_id = g.game_id WHERE g.genre IS NOT NULL GROUP BY g.genre ORDER BY g.genre;

[User] Thanks. Can you modify the query to only include games that were released after the year 2020?

[Assistant] SELECT g.genre, COUNT(gs.session_id) AS session_count, COUNT(DISTINCT gs.player_id) AS player_count FROM gaming_technology.game_sessions AS gs JOIN gaming_technology.games AS g ON gs.game_id = g.game_id WHERE g.genre IS NOT NULL AND g.release_date >= '2021-01-01' GROUP BY g.genre ORDER BY g.genre;
