Anyone can help me with this quiz?

See if there are any customers who have a different city listed in their billing city versus their customer city.
Here is the code i put. Also the quiz uses this database

SELECT Customers.CustomerId
FROM Customers left join Invoices

Hello @shuzeinashuzu9192911 , You will need to do an inner join the Customers and Invoices tables first, using CustomerId, in order to generate a list of BillCity values for that customer.
