sql-基于另一个表上的列的条件查询（日期范围）

Question

我这里有2张桌子， 一个像查询表（会话），一个像交易表（事务）

session     
id  start_time          end_time
1   2020-08-13 06:47:18 2020-08-13 18:48:42
2   2020-08-13 18:49:21 2020-08-14 06:52:31

transaction 
id  payment_time
1   2020-08-13 06:49:18
2   2020-08-13 06:54:11
3   2020-08-14 06:44:00
4   2020-08-14 06:47:37

如何查询以获取下面的输出，它可以根据查找表值返回会话？

end_result      
id  payment_time          session
1   2020-08-13 06:49:18    1
2   2020-08-13 06:54:11    1
3   2020-08-14 06:44:00    2
4   2020-08-14 06:47:37    2

Answer 1

SELECT t.id AS id, t.payment_time, s.id AS session
FROM [session] s
INNER JOIN [transaction] t ON s.start_time <= t.payment_time AND s.end_time >= t.payment_time

Answer 2

您可以尝试以下操作：

select T.id, T.payment_time, S.id
from [transaction] as T
inner join [session] as S on T.payment_time between S.start_time and S.end_time
