I have a table like this:
[SDate - DateTime] [Value - Decimal]
2010-11-16 10:32:22 1
2010-11-16 10:58:08 2
and I need a query to group records by n minutes interval.
Output can be for example(grouped by 60 minutes):
2010-11-16 10:10:00 avg(Value)
2010-11-16 10:11:00 avg(Value)
2010-11-16 10:12:00 avg(Value)
Up to now, I have been using this query to group by 10 minutes interval because intervals were between 0 and 60 minutes:
(DATEPART(MINUTE, SDate) / 10)
But now the interval can be 125436758
minutes, for example.
I can not create new tables and the user-defined interval must be n minutes.
I am using SQL SERVER 2012. Thanks.
