Review Summary
I am approving your solution because your task.sql file fully implements the required ShopDB schema and meets all core specifications. You correctly created the ShopDB database and defined the Products, Customers, Orders, and OrderItems tables with the exact columns and allowed data types (INT, DATE, VARCHAR(50), VARCHAR(100)). All primary keys are INT AUTO_INCREMENT and properly declared as primary keys, which matches the task requirements. The foreign key relationships are also correctly set up: Orders.CustomerID references Customers(ID), and OrderItems.OrderID and OrderItems.ProductID reference Orders(ID) and Products(ID) respectively, all using ON DELETE SET NULL as requested. Functionally, this script should run successfully on MySQL and produce the desired schema for the online shop. As a small, non-blocking improvement, you could remove any stray trailing characters (like extra backticks) after the last ); to keep the script perfectly clean. Overall, you’ve met the task requirements well—nice work on a clear and compliant SQL schema.
