Thank you for your hard work on this SQL script! 😊 You've done a great job in setting up the database and tables with the necessary relationships. However, there's a critical issue that needs to be addressed before we can approve the pull request. The foreign key columns (CustomerID, OrderID, and ProductID) in your tables need to allow NULL values because the ON DELETE SET NULL action is used. Without allowing NULLs, this will cause errors when trying to set these columns to NULL upon deletion of the referenced rows. Please update the column definitions to allow NULL values, and then we can proceed with approval. Keep up the great work! 🚀

The CustomerID column should allow NULL values since the foreign key constraint uses ON DELETE SET NULL. Add NULL to the column definition to avoid errors.

Great job on addressing the previous critical issue by allowing NULL values for the foreign key columns (CustomerID, OrderID, and ProductID) in the Orders and OrderItems tables. This change ensures that the ON DELETE SET NULL action works correctly, preventing errors when referenced rows are deleted. Your code now meets the task requirements and is ready for approval. 🎉
