创建Goods和GoodsDetai表和添加数据

可以使用以下SQL语句创建Goods和GoodsDetail表：

CREATE TABLE Goods (
    id INT PRIMARY KEY AUTO_INCREMENT,
    name VARCHAR(100) NOT NULL,
    price DECIMAL(10, 2) NOT NULL,
    description VARCHAR(255)
);

CREATE TABLE GoodsDetail (
    id INT PRIMARY KEY AUTO_INCREMENT,
    goods_id INT NOT NULL,
    color VARCHAR(50),
    size VARCHAR(50),
    FOREIGN KEY (goods_id) REFERENCES Goods(id)
);

然后，可以使用以下SQL语句向Goods和GoodsDetail表中添加一些数据示例：

INSERT INTO Goods (name, price, description) VALUES ('iPhone 12', 999.99, 'The latest iPhone model');
INSERT INTO Goods (name, price, description) VALUES ('Samsung Galaxy S21', 899.99, 'Flagship Android smartphone');

INSERT INTO GoodsDetail (goods_id, color, size) VALUES (1, 'Black', '128GB');
INSERT INTO GoodsDetail (goods_id, color, size) VALUES (1, 'White', '256GB');
INSERT INTO GoodsDetail (goods_id, color, size) VALUES (2, 'Phantom Gray', '128GB');
INSERT INTO GoodsDetail (goods_id, color, size) VALUES (2, 'Phantom Violet', '256GB');

这样就创建了Goods和GoodsDetail表，并向表中添加了一些示例数据
