这个简单的查询有什么不对？

Question

select ReplenishDate,Amount
from vw_replenishmentData
where (select max(ReplenishDate) from vw_replenishmentData)

Answer 1

您的where语句无效，请尝试以下操作：

select ReplenishDate,Amount 
from 
vw_replenishmentData 
where ReplenishDate= (select max(ReplenishDate) maxDate from vw_replenishmentData)

Answer 2

问题是您需要在哪里使用列名来过滤结果，例如.. where columnname = (select max(...

而不是使用subquery使用Top 1 with Ties。

select Top 1 with ties ReplenishDate,Amount
from vw_replenishmentData
order by ReplenishDate desc
