The task explicitly mentions that the order can be created using any date, for example 2023-01-01. Using CURDATE() is logically fine, but to match the requirement and possible tests more strictly, consider replacing CURDATE() with a fixed literal date like '2023-01-01'.

INSERT INTO OrderItems (OrderID, ProductID, Count) VALUES(LAST_INSERT_ID(), 1, 1);
UPDATE Products SET WarehouseAmount = WarehouseAmount - 1 WHERE ID = 1;

This update correctly decreases WarehouseAmount for product ID = 1 by the ordered count (1 here), matching the business rule. If you ever change the quantity in the OrderItems insert, consider using the same value here instead of a hard-coded 1 to keep them in sync.
