[User] Actually, I also want to see the user ID of the user who placed the order.

[Assistant] SELECT o.order_id, o.order_type, o.quantity, a.name, w.user_id FROM trading_platform.orders o JOIN trading_platform.assets a ON o.asset_id = a.asset_id JOIN trading_platform.wallets w ON o.wallet_id = w.wallet_id WHERE o.status = 'completed' AND o.quantity > 10;

[User] The previous query didn't work because some completed orders might not be linked to a wallet? Can you show the order ID, type, quantity, asset name, but also include the user ID if available through the wallet linkage, and still filter by 'completed' status and quantity > 10?

[Assistant] SELECT o.order_id, o.order_type, o.quantity, a.name, w.user_id FROM trading_platform.orders o JOIN trading_platform.assets a ON o.asset_id = a.asset_id LEFT JOIN trading_platform.wallets w ON o.wallet_id = w.wallet_id WHERE o.status = 'completed' AND o.quantity > 10;
