Thank you for your hard work on this task! Your SQL script is well-structured and meets most of the requirements. However, there are a few critical issues with the foreign key constraints that need to be addressed before we can approve the pull request. Specifically, the ON DELETE SET NULL action requires the foreign key columns to be nullable, which is not currently the case for the ProductID and OrderID columns in the OrderItems table, and the CustomerID column in the Orders table. Please update these columns to be nullable to ensure the foreign key constraints work as intended. Once these changes are made, your solution will be ready for approval. Keep up the great work! 😊

The CustomerID column in the Orders table should be nullable to support the ON DELETE SET NULL action. Consider changing the definition to CustomerID INT NULL.

Great job on addressing the previous issues with the foreign key constraints! 🎉 The SQL script is mostly correct, and you've made the CustomerID column in the Orders table, and the OrderID and ProductID columns in the OrderItems table nullable, which is necessary for using ON DELETE SET NULL. This aligns well with the task requirements.
However, ensure that the logic aligns with your database requirements. If the intention is to allow these fields to be nullable, then your implementation is correct. Otherwise, reconsider the foreign key constraints or the nullability of these columns.
The code now meets the task requirements and constraints as specified. There are no missing or unrelated files. Keep up the good work, and make sure to review the comments to further improve your code. Addressing these critical issues in the future will help you avoid similar problems and enhance your learning experience. Keep pushing forward! 🚀
