CREATE TABLE orders ( order_id INT PRIMARY KEY AUTO_INCREMENT, user_id INT, amount DECIMAL(10,2), status ENUM('待支付', '已支付', '已取消') DEFAULT '待支付', created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP );
CREATE TABLE products ( product_id INT PRIMARY KEY AUTO_INCREMENT, name VARCHAR(255), price DECIMAL(10,2), description TEXT );
CREATE TABLE payments ( payment_id INT PRIMARY KEY AUTO_INCREMENT, order_id INT, payment_method ENUM('支付宝', '微信支付', '信用卡'), status ENUM('待支付', '已支付', '已取消') DEFAULT '待支付', paid_at TIMESTAMP );
