SQL查询以查找开始日期和结束日期之间的总小时数

Question

这是我的示例表

id  from_time   to_time    user_login_id
1  1583721900 1583782500       2
2  1583721900 158378255        2
3  1583721900 1583782555       5
4  1583721900 1583782555       3

（日期时间存储在 UNIX 时间戳中）

我希望 SQL 查询在给定日期内获取开始和结束之间的总小时数

例如：我想从表中获取 01-02-2020 到 31-02-2020 之间的总小时数

 from-time             to_time         user_login_id
01-01-2020 10:00   01-01-2020 12:00       1
01-2-2020 10:00    02-01-2020 12:00       1
02-02-2020 10:00   02-02-2020 12:00       2
03-02-2020 10:00   03-02-2020 12:00       2

输出：

user_login_id total_hour
 2              4

它应该从 01-01-2020 之后开始的时间到 31-01-2020 之前结束的时间给出

提前致谢

这可能会按您的预期工作

SELECT FROM_UNIXTIME(`from_time`,'%Y-%m-%d %h:%i:%s'),FROM_UNIXTIME(`to_time`,'%Y-%m-%d %h:%i:%s'),user_login_id,SUM(TIMESTAMPDIFF(HOUR, FROM_UNIXTIME(`from_time`,'%Y-%m-%d %h:%i:%s'),FROM_UNIXTIME(`to_time`,'%Y-%m-%d %h:%i:%s'))) as total_hour
FROM 
  your_table_here
WHERE 
(FROM_UNIXTIME(`to_time`,'%Y-%m-%d') BETWEEN  STR_TO_DATE("01-03-2020",'%d-%m-%Y') and STR_TO_DATE("31-03-2020",'%d-%m-%Y')) and 
(FROM_UNIXTIME(`from_time`,'%Y-%m-%d') BETWEEN  STR_TO_DATE("01-03-2020",'%d-%m-%Y') and STR_TO_DATE("31-03-2020",'%d-%m-%Y'))
GROUP BY `user_login_id`

//here 01-03-2020 is considered as start date and 31-03-2020 is end date that you have to make dynamic
//note :- it will produce result only in hours and ignore minute difference if any
