关于mysql：GROUP_CONCAT ORDER BY

GROUP_CONCAT ORDER BY

我有一张桌子：

1
2
3
4
5
6
7
8
9
10
11
12

+-----------+-------+------------+
| client_id | views | percentage |
+-----------+-------+------------+
| 1 | 6 | 20 |
| 1 | 4 | 55 |
| 1 | 9 | 56 |
| 1 | 2 | 67 |
| 1 | 7 | 80 |
| 1 | 5 | 66 |
| 1 | 3 | 33 |
| 1 | 8 | 34 |
| 1 | 1 | 52 |

我试过group_concat：

1
2
3
4
5
6
7
8

SELECT li.client_id, group_concat(li.views) AS views,
group_concat(li.percentage) FROM li GROUP BY client_id;

+-----------+-------------------+-----------------------------+
| client_id | views | group_concat(li.percentage) |
+-----------+-------------------+-----------------------------+
| 1 | 6,4,9,2,7,5,3,8,1 | 20,55,56,67,80,66,33,34,52 |
+-----------+-------------------+-----------------------------+

但我希望按顺序获取视图，例如：

1
2
3
4
5

+-----------+-------------------+----------------------------+
| client_id | views | percentage |
+-----------+-------------------+----------------------------+
| 1 | 1,2,3,4,5,6,7,8,9 | 52,67,33,55,66,20,80,34,56 |
+-----------+-------------------+----------------------------+
