如何通過mysql獲取數據

我有如下的列表播放器。如何通過mysql獲取數據

+-----------+------------+------------+ 
| player_id | mission_id | reg_time | 
+-----------+------------+------------+ 
|   1 |   1 | 1508392600 | 
|   1 |   2 | 1508392800 | 
|   1 |   3 | 1508392900 | 
|   1 |   4 | 1508392822 | 
|   2 |   1 | 1508392500 | 
|   2 |   2 | 1508392600 | 
|   2 |   3 | 1508392900 | 
|   3 |   1 | 1508392600 | 
|   3 |   2 | 1508392600 | 
|   3 |   3 | 1508392900 | 
|   3 |   4 | 1508392900 | 
|   4 |   1 | 1508392600 | 
|   4 |   3 | 1508392900 | 
+-----------+------------+------------+

我想獲得所有player_id具有

mission_id = 1，2和reg_time < = 1508392800和

mission_id = 3，4和reg_time> 1508392800如下

+-----------+------------+------------+ 
| player_id | mission_id | reg_time | 
+-----------+------------+------------+ 
|   1 |   1 | 1508392600 | 
|   1 |   2 | 1508392800 | 
|   1 |   3 | 1508392900 | 
|   1 |   4 | 1508392822 | 
|   3 |   1 | 1508392600 | 
|   3 |   2 | 1508392600 | 
|   3 |   3 | 1508392900 | 
|   3 |   4 | 1508392900 |

到目前爲止您嘗試了什麼？ –

你已經提到了你的問題本身的所有條件。這是一個使用邏輯運算符將它們放入WHERE子句的問題。嘗試一下，如果在SQL語句中有任何失敗，請在此處發佈聲明。 – prabushitha

你可以試試這個代碼來得到你想要的結果。

SELECT * 
from `players` AS p 
where (exists (select * 
      from `players` as p1 
      where p1.player_id = p.player_id 
        AND p1.mission_id = 1 AND p1.reg_time <= 1508392800) 
    AND exists (select * 
      from `players` as p2 
      where p2.player_id = p.player_id 
        AND p2.mission_id = 2 AND p2.reg_time <= 1508392800)) 
AND (exists (select * 
      from `players` as p3 
      where p3.player_id = p.player_id 
        AND p3.mission_id = 3 AND p3.reg_time > 1508392800) 
    AND exists (select * 
      from `players` as p4 
      where p4.player_id = p.player_id 
        AND p4.mission_id = 4 AND p4.reg_time > 1508392800))

表中的reg_date列在哪裏提供，以及如何獲得執行的查詢 –

感謝您的建議。我試過你的代碼，但看起來不像我預期的我的預期結果像+ ----------- + ------------ + ------ ------ + | player_id | mission_id | reg_time | + ----------- + ------------ + ------------ + | 1 | 1 | 1508392600 | | 1 | 2 | 1508392800 | | 1 | 3 | 1508392900 | | 1 | 4 | 1508392822 | | 3 | 1 | 1508392600 | | 3 | 2 | 1508392600 | | 3 | 3 | 1508392900 | | 3 | 4 | 1508392900 | + ----------- + ------------ + ------------ + –

@ NareshKumar.P抱歉會相應地改變它 – Miggy
