在SQL中系统日期时间前10分钟获取记录

Question

我需要在系统当前日期时间前10分钟找到记录。

select Id,TimeStamp from ISAlive where RecordUpdatedDate < GETDATE() --SYSDATETIME()

Answer 1

select Id, TimeStamp
from ISAlive
WHERE RecordUpdatedDate = dateadd(minute,-10,getdate())

可能是一个起点。当然，它可能不会完全匹配...

...如果您想获得符合该标准的最新记录，请尝试

SELECT TOP 1 ID, TimeStamp
FROM ISAlive
WHERE RecordUpdatedDate <= dateadd(minute, -10, getdate())
ORDER BY RecordUpdatedDate DESC

Answer 2

SELECT Id, TimeStamp
FROM ISAlive 
WHERE RecordUpdatedDate < DATEADD(minute,-10, SYSDATETIME());

Answer 3

NOW() + INTERVAL 2 MINUTE
NOW() + INTERVAL 5 MINUTE               
NOW() + INTERVAL 10 MINUTE

Answer 4

您可以使用now（）完成此操作

SELECT Id, TimeStamp
FROM ISAlive 
WHERE RecordUpdatedDate <= NOW() - INTERVAL 10 MINUTE;
