mysql - SELECT * FROM MySQL 中的组合

Question

这是我的 MySQL 数据库:

+-----+------------+----------+----------------+--------------+-----------------+
| id  | data       | hora     | conexoes_total | conexoes_sim | conexoes_lentas |
+-----+------------+----------+----------------+--------------+-----------------+
|   1 | 2013-11-18 | 00:00:02 |            200 |            1 |              30 |
|   2 | 2013-11-18 | 10:15:03 |             14 |            2 |              25 |
|   3 | 2013-11-18 | 10:30:03 |             53 |            3 |              25 |
|   4 | 2013-11-18 | 10:45:02 |             60 |            5 |              26 |
|   5 | 2013-11-18 | 11:00:02 |             66 |            3 |              27 |
|   6 | 2013-11-18 | 11:15:03 |             74 |            5 |              27 |
                                         .
                                         .
                                         .

我想从每个 00:00:% 数据中选择 * 并插入最后一个值.. 我已经知道如何选择午夜值:SELECT * FROM audiencia WHERE hora LIKE '00:00:%';，这就是我得到的:

+-----+------------+----------+----------------+--------------+-----------------+
| id  | data       | hora     | conexoes_total | conexoes_sim | conexoes_lentas |
+-----+------------+----------+----------------+--------------+-----------------+
|   1 | 2013-11-18 | 00:00:02 |            200 |            1 |              30 |
|  57 | 2013-11-19 | 00:00:02 |            446 |            1 |              97 |
| 153 | 2013-11-20 | 00:00:02 |            300 |            3 |             173 |
| 349 | 2013-11-21 | 00:00:02 |             42 |            2 |              94 |
+-----+------------+----------+----------------+--------------+-----------------+

但现在我想显示插入表中的最后一个值以及上面的结果.. 我如何管理对我执行此操作的命令？

Answer 1

(SELECT * FROM audiencia WHERE hora LIKE '00:00:%')
UNION
(SELECT * FROM audiencia ORDER BY id DESC LIMIT 1);
