mysql 使用order by field() 自定义排序



1、mysql field自定义排序函数的格式

 

order by field(value,str1,str2,str3,str4,,,,,,strn)

其中value后面的参数自定义，不限制参数个数

 

含义

将获取出来的数据根据str1,str2,str3,str4等的顺序排序

 

 

2、mysql order by field 实例

 

mysql> select * from driver_log order by field(name,'Suzi','Ben','Henry');



--结果


+--------+-------+------------+-------+

| rec_id | name  | trav_date  | miles |

+--------+-------+------------+-------+

|      2 | Suzi  | 2006-08-29 |   391 |
