SQL select其中id ='x'的所有記錄的狀態爲'y'

Question

我有一個表incoming，其中包含電子郵件列表及其附件。

我導入每個附着物的，並對其進行處理，此時作爲5

當個人的電子郵件中的所有行被標記爲5該行被標記的話，我可以移動/刪除的電子郵件，因爲它已被正確處理。

不過，我掙扎寫一個SQL查詢是選擇msg_uid，因爲具有相同msg_uid所有行的5

例表

----------------------------------------------------- 
| id | STATUS | i2d_id | msg_uid | i2d_msg   | 
----------------------------------------------------- 
| 16 | 5  | 98390 | 53  | Result is ready. | 
----------------------------------------------------- 
| 17 | 3  | 98391 | 53  | Result is ready. | 
----------------------------------------------------- 
| 18 | 5  | 98392 | 53  | Result is ready. | 
----------------------------------------------------- 
| 19 | 3  | 98393 | 53  | Result is ready. | 
----------------------------------------------------- 
| 20 | 5  | 98394 | 53  | Result is ready. | 
----------------------------------------------------- 

狀態這不會允許我刪除的電子郵件（有些人狀態3

但

----------------------------------------------------- 
| id | STATUS | i2d_id | msg_uid | i2d_msg   | 
----------------------------------------------------- 
| 16 | 5  | 98390 | 53  | Result is ready. | 
----------------------------------------------------- 
| 17 | 5  | 98391 | 53  | Result is ready. | 
----------------------------------------------------- 
| 18 | 5  | 98392 | 53  | Result is ready. | 
----------------------------------------------------- 
| 19 | 5  | 98393 | 53  | Result is ready. | 
----------------------------------------------------- 
| 20 | 5  | 98394 | 53  | Result is ready. | 
----------------------------------------------------- 

會成功。

Answer 1

SELECT msg_uid 
FROM yourTable 
GROUP BY msg_uid 
HAVING COUNT(*) = COUNT(CASE WHEN STATUS = 5 THEN 1 END) 

Answer 2

此查詢會讓同比找到每一個結果，所有的STATUS值是5特定msg_uid：

SELECT * 
FROM incoming i 
WHERE NOT EXISTS(SELECT 1 FROM incoming 
       WHERE msg_uid = i.msg_uid 
       AND `status` <> 5);
