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
按 name 以 'Suzi','Ben','Henry' 的顺序排列
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 || 7 | Suzi | 2006-09-02 | 502 || 1 | Ben | 2006-08-30 | 152 || 9 | Ben | 2006-09-02 | 79 || 5 | Ben | 2006-08-29 | 131 || 8 | Henry | 2006-09-01 | 197 || 6 | Henry | 2006-08-26 | 115 || 4 | Henry | 2006-08-27 | 96 || 3 | Henry | 2006-08-29 | 300 || 10 | Henry | 2006-08-30 | 203 |+--------+-------+------------+-------+
