sql - 取下一个日期值 SQL Server

Question

我有一张表 (A) 和另一张表 (B)，其中包含以下信息:

我想做的是在图像中得到类似FINAL DATA 的东西...... 如果 Receipt 值与同一天的 ExecutionDate+ExecutionTime 不匹配...查询应该取第一个 next ExecutionDate+ExecutionTime

让我向您解释一下我想从 2 家零售商那里得到什么:

COSTWH - 2017-12-26 11:15:09:000

这个应该取值

SellThru Refresh - 表B中2017-12-26 23:30:00

因为接收日期早于执行时间(11:15:09:000 对 23:30:00)所以最终数据应该是这样的

COSTWH - 2017-12-26 11:15:09:000 - 2017-12-26 23:30:00

对于 AMAZONCA - 2017-12-26 23:59:08:000 -----

表B的值应该是

SellThru 刷新 - 2017-12-27- 04:30:00

为什么？ --- 因为收货日期是在当天最后一次执行之后('2017-12-26 23:59:08:000' VS '2017-12-26 23:30:00')所以查询应该取下一个最接近的执行，在这种情况下是 '2017-12-27','04:30:00'

所以 AMAZONCA 的数据应该是这样的

亚马逊 - 2017-12-26 23:59:08:000 - 2017-12-27 04:30:00'

Answer 1

那么应该是这样的:

select distinct Retailer
     , ReceiptDate
     , (select min(CAST(ExecutionDate AS DATETIME) + CAST(StartTime AS DATETIME))  -- first appearance
        from TableB
        where CAST(ExecutionDate AS DATETIME) + CAST(StartTime AS DATETIME) >= TableA.ReceiptDate) DataRefresh  
from TableA 
order by Retailer
     , ReceiptDate 

结果是这样的:
