从本周星期一 18:00 选择值

Question

我只在本周的星期一和 18:00 到 19:00 尝试从 MySQL 获取值。我该怎么做？

结果应该是：1

m_z_analytics

|id|m_type|date_added         |
|1 |test1 |2018-06-25 18:02:09|
|2 |test2 |2018-06-26 19:44:24|


SELECT COUNT(id) AS id FROM m_z_analytics WHERE
Week(date_added) = Week(CURRENT_TIMESTAMP) AND
date_added >= (NOW() - INTERVAL 7 DAY) AND
date_added < (NOW() - INTERVAL 6 HOUR)

Answer 1

使用WEEKDAY() 或DAYNAME() 函数测试星期几，使用HOUR() 测试一天中的时间。

SELECT COUNT(*)
FROM m_z_analytics
WHERE date_added BETWEEN NOW() - INTERVAL 1 WEEK AND NOW() - INTERVAL 6 HOUR
AND HOUR(date_added) = 18
AND DAYNAME(date_added) = 'Monday'

您不需要WEEK() 函数，因为时间间隔缩小到当前一周。
