显示产品列表之类的内容的 sql 语句是什么

Question

如何在图片

中显示客户"Peacock cafe bar"购买的产品（description，serial number，price）

我显示 3 个表

我试过

select 
from ...
where(
    select
    from ...
    as ...
    where 
    “”
)

Answer 1

我记得你应该在你的表上使用联合查询，比如：

select * from ProductsTable as Products
join  
(select Buys.ProCode from CustomerTable as Customer
join BuysTable as Buys
on Customer.code = Buys.custcode) as customerbuys
on Products.code = customerbuys.ProCode

Answer 2

尝试这样的事情：您将希望通过它们的键连接您的表，然后像这样在 WHERE 子句中过滤结果。

SELECT
   p.pr_serial
 , p.pr_descr
 , p.pr_price
FROM   Customers AS c
JOIN Buys AS b
    ON c.cust_code = b.cust_code
JOIN Products AS p
    ON b.pr_code = p.pr_code
WHERE  c.cust_name = 'Peacock cafe bar';
