Question

我需要顯示cust_id，客戶的姓氏和姓氏，產品名稱<-（來自產品表）和銷售日期<-（來自銷售表），還需要按最新日期的順序顯示。

到目前為止，這是我得到的：

SELECT   
   customer.cust_id, 
   customer.forename, 
   customer.surname, 
   products.prod_name, 
   sales.Date_of_sale
FROM customers c
    INNER JOIN sales s ON c.cust_id = s.cust_id
    INNER JOIN products p ON s.product_id = p.product_id
ORDER BY s.Date_of_sale DESC

任何幫助，將不勝感激。
