mysql 使用order by field() 自定义排序
一、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
二、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 |
+--------+-------+------------+-------+
