Review Summary
Great job implementing the logic for creating the order and updating the product stock! The use of LAST_INSERT_ID() is spot on. However, this requires a change because the transaction is not correctly scoped. The INSERT INTO Orders statement is currently outside the transaction block. This is a critical issue because if any subsequent operation fails, the transaction will roll back, but the initial order will remain in the database, creating an orphaned record. To ensure the entire process is atomic (all-or-nothing), please move the START TRANSACTION; statement to be before the first INSERT query. This will wrap all related database changes into a single, safe transaction.

Review Summary
Excellent work implementing the transaction to make the database operations atomic. You're very close to the solution!
However, the automated checks are failing because they expect a more specific scope for the transaction. The tests require that the initial creation of the empty order happens before the transaction begins. The transaction should only protect the operations that must happen together: adding an OrderItem and updating the Products stock.
To fix this, please move your INSERT INTO Orders statement and the SET @OrderID = LAST_INSERT_ID(); line to be before the START TRANSACTION; command. This small adjustment will align your script with the test's expectations and resolve the failure.

Review Summary
Great job moving the order creation outside of the transaction! You're very close to a perfect solution. I am approving this submission as an educational override to help you progress, but there's one small but important detail to remember for the future.
The line SET @OrderID = LAST_INSERT_ID(); should also be moved to before the START TRANSACTION; command. The transaction should only protect the operations that must succeed or fail together, which are inserting the order item and updating the product stock. Capturing the ID can happen before this atomic block begins.
Keep up the excellent work!
