我有一个类似于这样的表格:链接
+-----------+-------+------------+
| 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 |
我尝试了 group_concat
:
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 |
+-----------+-------------------+-----------------------------+
但是我想按顺序获取视图,例如:
+-----------+-------------------+----------------------------+
| client_id | views | percentage |
+-----------+-------------------+----------------------------+
| 1 | 1,2,3,4,5,6,7,8,9 | 52,67,33,55,66,20,80,34,56 |
+-----------+-------------------+----------------------------+
