在 MySQL 表中，我想对通过 ORDER BY FIELD() 获取的记录组进行排序
更具体地说， 假设，我运行了以下查询:
SELECT name,status,date FROM memberTickets ORDER BY FIELD(status,7,10,3,4) ASC
得到如下结果:
---------------------------------------------------------
| name | status | date |
---------------------------------------------------------
| A | 7 | 2015-05-05 00:00:00 |
---------------------------------------------------------
| B | 7 | 2015-05-07 00:00:00 |
---------------------------------------------------------
| C | 7 | 2015-05-03 00:00:00 |
---------------------------------------------------------
| D | 10 | 2015-05-08 00:00:00 |
---------------------------------------------------------
| E | 10 | 2015-05-01 00:00:00 |
---------------------------------------------------------
| F | 10 | 2015-05-05 00:00:00 |
---------------------------------------------------------
| G | 10 | 2015-05-05 00:00:00 |
---------------------------------------------------------
| H | 3 | 2015-05-03 00:00:00 |
---------------------------------------------------------
| I | 3 | 2015-05-08 00:00:00 |
---------------------------------------------------------
| J | 3 | 2015-05-01 00:00:00 |
---------------------------------------------------------
| K | 4 | 2015-05-05 00:00:00 |
---------------------------------------------------------
| l | 4 | 2015-05-07 00:00:00 |
---------------------------------------------------------
现在，我想以这样的方式对记录进行排序，使记录组的位置保持不变(按字段顺序设置)，但每组中的记录按日期属性降序排列，如下所示:
---------------------------------------------------------
| name | status | date |
---------------------------------------------------------
| A | 7 | 2015-05-07 00:00:00 |
---------------------------------------------------------
| B | 7 | 2015-05-05 00:00:00 |
---------------------------------------------------------
| C | 7 | 2015-05-03 00:00:00 |
---------------------------------------------------------
| D | 10 | 2015-05-08 00:00:00 |
---------------------------------------------------------
| E | 10 | 2015-05-05 00:00:00 |
---------------------------------------------------------
| F | 10 | 2015-05-05 00:00:00 |
---------------------------------------------------------
| G | 10 | 2015-05-01 00:00:00 |
---------------------------------------------------------
| H | 3 | 2015-05-08 00:00:00 |
---------------------------------------------------------
| I | 3 | 2015-05-03 00:00:00 |
---------------------------------------------------------
| J | 3 | 2015-05-01 00:00:00 |
---------------------------------------------------------
| K | 4 | 2015-05-07 00:00:00 |
---------------------------------------------------------
| l | 4 | 2015-05-05 00:00:00 |
---------------------------------------------------------
关于如何做到这一点有什么想法或建议吗？
最佳答案
您通常可以像这样为 ORDER BY 指定任意数量的排序参数
SELECT name,status,date FROM memberTickets ORDER BY FIELD(status,7,10,3,4) ASC, date DESC
