Question

I have a table that looks like this

id   |   refreshTime   |   lastRanAt             |   otherFeilds
1    |   60            |   2012-05-14 14:25:08   |   somthing
2    |   30            |   2012-05-14 15:25:08   |   something else
3    |   20            |   2012-05-03 16:25:08   |   foo

I would like to return results where the ‘lastRanAt’ datetime is less than the currentTime minus the refreshTime (the refreshTime is in minutes)

Can this be done in one query?

Thanks in advance

Answer 1

Something like this?

select * 
from Table t
where lastRanAt < dateadd(mi, (t.refreshTime * -1), getdate())
