mysql - Mysql查询不显示不等值的行

Question

我的 mysql 查询有一个小问题。我只想显示订单状态不同于6. 但是 Theid_order有多个雕像，这意味着例如：

id_order = 8421
**has two statuses:**
id_order_state=8 and
id_order_state = 6.

这是我的表的示例：链接

我试过：

SELECT * FROM order_history WHERE id_order_state != 6 (but here I need more code that I can't handle)

谢谢你的帮助

编辑：订单 8421、8422 不应显示在结果中

Answer 1

试试这个

> SELECT * FROM order_history WHERE id_order_state <> 6

或者

> SELECT * FROM order_history WHERE id_order_state NOT IN ( 6)

Answer 2

尝试：

SELECT i.* FROM order_history i
left join order_history e 
       on i.id_order = e.id_order and e.id_order_state = 6
WHERE  e.id_order_hitory is null

Answer 3

像这样？

SELECT * 
FROM order_history 
WHERE id_order NOT IN 
(SELECT id_order FROM order_history WHERE id_order_state = 6);
