How to return lists of invoices ordered by using SQL server?

write a SQL query to return a list of all the invoices. For each invoice, show the Invoice ID, the billing date, the customer’s name, and the name of the customer who referred that customer (if any). The list should be ordered by billing date.

// Invoices

      ,[ReferredBy]  
  FROM [eNtsaRegistration].[dbo].[Customers]
