Thank you for your hard work on this SQL script! 😊 While your solution meets many of the task requirements, there are a few critical issues that need to be addressed before we can approve the pull request:
-
Foreign Key Constraints: The
ON DELETE SET NULLoption is used in your foreign key constraints, but the related columns (OrderIDandProductIDinOrderItems, andCustomerIDinOrders) are not nullable. This will cause errors when trying to set these columns toNULL. Please make these columns nullable to align with theON DELETE SET NULLbehavior. -
Data Type for Price: The
Pricecolumn in theProductstable is currently anINT, which may not accommodate fractional values that are common in pricing. Consider changing this to aDECIMALtype to better handle such cases.
Once these issues are resolved, your script will be in great shape! Keep up the great work, and I'm looking forward to your updated submission. 🚀

Consider using a DECIMAL type for the Price column instead of INT to handle fractional prices, which are common in product pricing.

The CustomerID column in the Orders table should be nullable if you intend to use ON DELETE SET NULL. Otherwise, this will cause an error when trying to set a non-nullable column to NULL.

Great job on addressing the previous issues! 🎉 The SQL script is now well-structured and meets the task requirements. You've successfully updated the Price column in the Products table to DECIMAL(10,2), which is perfect for handling fractional values. Additionally, making the CustomerID in the Orders table, as well as OrderID and ProductID in the OrderItems table nullable, aligns with the ON DELETE SET NULL behavior in the foreign key constraints.
While the code is approved, remember to review the comments to further enhance your skills. Addressing any critical issues in the future will help you avoid similar problems and improve your coding proficiency. Keep up the great work and continue learning from your experiences! 🚀
