mysql查詢不顯示行不等於值

Question

我的mysql查詢有一個微不足道的問題。我只想顯示訂單狀態不同於6的行。但id_order有多個雕像這意味着如：

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

我這裏是我的表：

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

感謝所有幫助

我嘗試：訂單8421,8422不應顯示在結果中

Answer 1

嘗試：

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 2

試試這個

> SELECT * FROM order_history WHERE id_order_state <> 6 

或

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

Answer 3

就這樣？

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