Question

我需要显示cust_id，客户的姓名和姓氏，产品名称＆lt ;-(来自产品表）和销售日期＆lt; - （来自销售表），我还需要按最近的日期顺序显示第一

这是我到目前为止所得到的：

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

任何帮助都将不胜感激。
