好吧,我正在进行一项任务,我们正在使用JOIN ... ON语句,而且我不确定我做错了什么,但是当我将SQL代码运行到数据库中时什么都没有出现.

编辑:没有收到任何错误.代码运行没有缺陷.

谁知道我做错了什么？对于这种情况,INNER JOIN是正确的联接吗？(可以在代码末尾找到Join语句...)

 SELECT orders.order_ID as 'Order ID'
      , orders.order_date as 'Order Date'
  , CONCAT(customers.customer_first_name, ' ', customers.customer_last_name) as 'Customer'
   , customers.customer_city as 'City'
FROM Orders
JOIN Customers
  ON orders.customer_ID = customers.customer_ID
 WHERE customer.customer_state = 'OH'
 ORDER BY orders

所有的SQL ......
