Review Summary

Your solution demonstrates correct transaction logic for placing the OrderItems insertion and Products warehouse update within the transaction boundary. However, this requires changes before approval.

Critical blocker: Your task.sql must begin with DROP DATABASE IF EXISTS ShopDB; followed by recreating the database using the script from create-database.sql before executing USE ShopDB;. The task explicitly requires recreating the database from scratch, and without this step, test reruns will fail because tables won't be empty.

Additional improvement: Your INSERT INTO OrderItems uses a hardcoded OrderID = 1 which assumes the Orders table is empty. Use LAST_INSERT_ID() or a subquery to dynamically retrieve the newly created order's ID, ensuring the script works correctly regardless of existing data.

Once you add the database recreation commands at the beginning of the script and fix the OrderID retrieval, the implementation should work correctly.

The task requires recreating the database from scratch. Add DROP DATABASE IF EXISTS ShopDB; at the beginning to ensure a clean state, then create the database using the script from create-database.sql before proceeding.

Review Summary

Your solution is approved. The implementation successfully meets all requirements: the database is recreated from scratch using DROP DATABASE IF EXISTS ShopDB; followed by CREATE DATABASE ShopDB; and USE ShopDB;, all required tables (Products, Customers, Orders, OrderItems) are created and populated with sample data, the OrderID is retrieved dynamically via LAST_INSERT_ID() instead of being hardcoded, and the transaction properly wraps both the OrderItems insertion and the Products warehouse update. All checklist items have been satisfied with no remaining issues.
