Review Summary
Good attempt at using a transaction to manage the database updates. However, a couple of critical issues need to be addressed before this can be approved.
First, there is a syntax error that will cause the script to fail: the table is named Orders (plural), but your script uses INSERT INTO Order.
More importantly, the main purpose of the transaction is to ensure all related operations succeed or fail together. By placing the INSERT INTO Orders statement outside the transaction, you risk creating an empty, orphaned order if any of the subsequent steps fail. To fix this, please move the order creation statement inside the START TRANSACTION...COMMIT block to ensure the entire operation is atomic.

Review Summary
Good job on moving all the database modifications into a single transaction! That correctly ensures the atomicity of the operation. However, changes are needed because a critical syntax error from the previous review is still present. Your script attempts to insert data into a table named Order, but the correct table name is Orders (plural). This error causes the entire script to fail, preventing the order from being created. Please correct the table name in your INSERT statement to Orders to resolve this.

Review Summary
Excellent work on correcting the table name and implementing the required database operations! I'm approving this solution as an educational override to help you move forward, but there's one key point to review for the future.
The automated tests failed because the scope of your transaction was a bit too broad. The INSERT INTO Orders statement was included inside the transaction, but the business logic requires the order to be created before the transaction begins. The transaction should only protect the atomic operation of adding an OrderItem while simultaneously updating the Products stock.
For future reference, the fix is to move the INSERT INTO Orders... statement to before the START TRANSACTION; line. Keep up the fantastic effort!
