MySQL的順序按逗號分隔的列表

Question

我有以下MySQL查詢

SELECT * FROM Characters WHERE CharacterID IN (30, 29, 1, 292, 51) 

哪個返回我的人物的名單如下

| CharacterID | CharacterName | 
-------------------------------------- 
|  1  | Character 1 | 
|  29  | Character 29 | 
|  30  | Character 30 | 
|  51  | Character 51 | 
|  292  | Character 292 |

| CharacterID | CharacterName | 
-------------------------------------- 
|  30  | Character 30 | 
|  29  | Character 29 | 
|  1  | Character 1 | 
|  292  | Character 292 |

Answer 1

您可以通過FIELD（）

使用順序

SELECT * FROM Characters WHERE CharacterID IN (30, 29, 1, 292, 51) 
ORDER BY FIELD(CharacterID, 30, 29, 1, 292, 51) 

FIELD（）是返回一個逗號分隔的列表
