SQL 开始日期和结束日期匹配

Question

我有一张包含客户 ID 和开始日期的表以及一张包含客户 ID 和结束日期的表。

表A

customer_id	start_date
1	2022-01-01
1	2022-04-01
1	2022-07-01
2	2022-01-15
2	2022-03-25
3	2022-04-01
3	2022-08-01
4	2022-09-01

表B

customer_id	end_date
1	2022-01-25
1	2022-05-03
2	2022-03-24
2	2022-03-29
3	2022-04-15

有没有一种方法可以获得如下所示的输出？

期望的输出

customer_id	start_date	end_date
1	2022-01-01	2022-01-25
1	2022-04-01	2022-05-03

Answer 1

此提示在 SQL Server 中使用 TSQL。

select A.customer_id, A.start_date, B.end_date
from 
    (select X.costumer_id, X.start_date, ROW_NUMBER() over (order by X.start_date) as ORDEM from TableA X) A
    left outer join (select X.customer_id, X.end_date, ROW_NUMBER() over (order by X.end_date ) as ORDEM  from TableB X) B on A.customer_id = B.customer_id and A.ORDEM = B.ORDEM
order by A.customer_id, A.start_date
