标题: mysql中字段类型转换排序
所以我们也可以用CAST解决问题：

select server_id from cardserver where game_id = 1 order by CAST(server_id as SIGNED) desc limit 10;
+-----------+
| server_id |
+-----------+
| 10       |
| 8       |
| 7       |
| 6       |
| 5       |
| 4       |
| 3       |
| 2       |
| 1       |
+-----------+
也可以使用CONVERT来搞定此问题：

select server_id from cardserver where game_id = 1 order by CONVERT(server_id,SIGNED) desc limit 10;
+-----------+
| server_id |
+-----------+
| 10       |
| 8       |
| 7       |
| 6       |
| 5       |
| 4       |
| 3       |
| 2       |
| 1       |
+-----------+
