[User] Show me the top 5 users who have the highest total trade volume (quantity * price) as buyers, along with their email addresses and the number of distinct assets they traded.

[Assistant] SELECT u.user_id, u.email, COUNT(DISTINCT t.asset_id) AS distinct_assets_traded, SUM(t.quantity * t.price) AS total_trade_volume FROM trading_platform.users u JOIN trading_platform.trades t ON u.user_id = t.buyer_id GROUP BY u.user_id, u.email ORDER BY total_trade_volume DESC LIMIT 5;

[User] Now modify the query to include only trades that happened in the last 30 days and show the average trade price for each buyer.

[Assistant] SELECT u.user_id, u.email, COUNT(DISTINCT t.asset_id) AS distinct_assets_traded, SUM(t.quantity * t.price) AS total_trade_volume, AVG(t.price) AS average_trade_price FROM trading_platform.users u JOIN trading_platform.trades t ON u.user_id = t.buyer_id WHERE t.traded_at >= NOW() - INTERVAL '30 days' GROUP BY u.user_id, u.email ORDER BY total_trade_volume DESC LIMIT 5;

[User] Actually, I want to see the top 5 buyers by total trade volume who also have wallets, and include their wallet addresses.

[Assistant] SELECT u.user_id, u.email, w.address AS wallet_address, SUM(t.quantity * t.price) AS total_trade_volume FROM trading_platform.users u JOIN trading_platform.trades t ON u.user_id = t.buyer_id JOIN trading_platform.orders o ON t.order_id = o.order_id JOIN trading_platform.utxos w ON o.wallet_id = w.address WHERE w.spent = false GROUP BY u.user_id, u.email, w.address ORDER BY total_trade_volume DESC LIMIT 5;

[User] Show me the top 5 ERC20 tokens with the highest total supply, along with their names and contract addresses, but only include tokens where the price is greater than $0.1.

[Assistant] SELECT tm.name, tm.contract_address, tm.total_supply, tpl.price FROM token_metas tm JOIN token_prices_latest tpl ON tm.contract_address = tpl.address WHERE tm.is_erc20 = 1 AND tpl.price > 0.1 ORDER BY CAST(tm.total_supply AS decimal) DESC LIMIT 5;

[User] I think there's an error in your query - it should be 'tpl.symbol' not 'tm.symbol'. Also, can you add the decimals to the results?

[Assistant] SELECT tm.name, tm.contract_address, tm.decimals, tm.total_supply, tpl.symbol, tpl.price FROM token_metas tm JOIN token_prices_latest tpl ON tm.contract_address = tpl.address WHERE tm.is_erc20 = 1 AND tpl.price > 0.1 ORDER BY CAST(tm.total_supply AS decimal) DESC LIMIT 5;

[User] Now filter these results to only show tokens with decimals equal to 18.

[Assistant] SELECT tm.name, tm.contract_address, tm.decimals, tm.total_supply, tpl.symbol, tpl.price FROM token_metas tm JOIN token_prices_latest tpl ON tm.contract_address = tpl.address WHERE tm.is_erc20 = 1 AND tpl.price > 0.1 AND tm.decimals = 18 ORDER BY CAST(tm.total_supply AS decimal) DESC LIMIT 5;
