Good to use the correct database with USE ShopDB; — ensure you ran the create-database.sql script beforehand so this database exists before running these statements.

You created an index on Customers(Email), which is appropriate for login-by-email queries. The task also expects indexes on other tables/columns inferred from the usage scenario — those are currently missing.


CREATE INDEX Name ON Products(Name);

CREATE INDEX CustomerID ON Orders(CustomerID);

CREATE INDEX OrderID ON OrderItems(OrderID);

CREATE INDEX ProductID ON OrderItems(ProductID);
