我有一个表,其中有两列。一列(callstart)显示调用开始时间。显示调用结束时间的另一列(callend)。
现在我想做一个单日的结果,这将是在那里的条件,如有多少个电话运行的时间。在那个时间已经开始了多少个电话。
表格:
+-------------+-------------+------+-----+---------------------+-------+
| Field | Type | Null | Key | Default | Extra |
+-------------+-------------+------+-----+---------------------+-------+
| id | int(11) | NO | | NULL | |
| user_id | int(11) | YES | | 0 | |
| callstart | datetime | NO | | 0000-00-00 00:00:00 | |
| callend | datetime | NO | | 0000-00-00 00:00:00 | |
+-------------+-------------+------+-----+---------------------+-------+
4 rows in set (0.00 sec)
预期结果:
+----+-----------+---------------------+----+-----+
| id | user_id | date | cc | cps |
+----+-----------+---------------------+----+-----+
| 1 | 3 | 2018-04-02 19:47:27 | 0 | 1 |
| 2 | 3 | 2018-04-02 19:48:52 | 1 | 1 |
| 3 | 3 | 2018-04-02 19:48:53 | 1 | 0 |
| 4 | 3 | 2018-04-02 19:48:54 | 1 | 0 |
| 5 | 3 | 2018-04-02 19:48:55 | 1 | 0 |
+----+-----------+---------------------+----+-----+
在上述结果中:
cc:在特定时间运行的并发调用。在特定时间开始的呼叫。
注:
1. mysql version is 5.5.
2. In above table,Data will be available only for single day( A call which has been ended on day upto call has been started on a day).
3.I have make it working with php script.But its take long time to manage 6 months record.So i would like to make query which can gives result for every single day.

按热度按时间qvtsj1bj1#
编辑:我以前不理解这个问题,但看到预期的结果让我明白了这一点。为了在时间窗口中每秒钟有一行,您需要创建一个包含所有要显示的时间的表。
像这样:
然后,需要运行以下查询:
这是小提琴
