我有一个表some_table像
+--------+----------+---------------------+-------+
| id | other_id | date_value | value |
+--------+----------+---------------------+-------+
| 1 | 1 | 2011-04-20 21:03:05 | 104 |
| 2 | 2 | 2011-04-20 21:03:04 | 229 |
| 3 | 3 | 2011-04-20 21:03:03 | 130 |
| 4 | 1 | 2011-04-20 21:02:09 | 97 |
| 5 | 2 | 2011-04-20 21:02:08 | 65 |
| 6 | 3 | 2011-04-20 21:02:07 | 101 |
| ... | ... | ... …简而言之,我正在尝试按列进行分组,但仅当该列不是null或者0在这种情况下我仍然想要获取这些行,但只是没有分组.我有这张桌子some_table:
+--------+----------+---------------------+-------+
