我还想要订单详细信息，例如订单列

Question

select o.*,x.cust_name  from(
select cust_name from customer c where salesman_id IN(
select salesman_id from Orders o where ord_date ='2012-08-17'))x 

我只有客户名称，但我还需要订单列。我想在子查询中解决

ord_no	purh_amt	ord_date	cust_id	salesman_id	cust_name
70011	75.29	2012-08-17	3003	5007	jozy
7004	110.5	2012-08-17	3009	5003	geoff

Answer 1

如果我理解你想要实现的目标，你需要像这样的内部连接：

select ord_no,cust_name,ord_date 
  from customer c
  inner join orders o
    on (c.salesman_id = o.salesman_id)
  where o.ord_date = '2012-08-17';
