sql server - Get records 10 min before system datetime in SQL

Question

i need to find the records 10 min before system current datetime.

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

Answer 1

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

might be a starting point. Of course, it probably won't match exactly...

...if you want to get the most recent record that fits that criteria, however, try

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