PHP プログラミング ガイド: 複数の製品仕様 SKU を実装する方法

CREATE TABLE products (
  id INT PRIMARY KEY AUTO_INCREMENT,
  name VARCHAR(255) NOT NULL,
  description TEXT
);

CREATE TABLE specifications (
  id INT PRIMARY KEY AUTO_INCREMENT,
  name VARCHAR(255) NOT NULL
);

CREATE TABLE specification_options (
  id INT PRIMARY KEY AUTO_INCREMENT,
  specification_id INT,
  option_name VARCHAR(255) NOT NULL,
  FOREIGN KEY (specification_id) REFERENCES specifications(id)
);

CREATE TABLE skus (
  id INT PRIMARY KEY AUTO_INCREMENT,
  product_id INT,
  sku_code VARCHAR(255) NOT NULL,
  specification_values TEXT,
  price DECIMAL(10, 2),
  stock INT,
  FOREIGN KEY (product_id) REFERENCES products(id)
);
