Re: possible to do a group by on a time interval? (or some other way to do this)

Maybe something like:

SELECT FLOOR(EXTRACT(minute FROM mytimestamp) / 15)*15 AS period
   , COUNT(*)
FROM   metrictable
GROUP BY FLOOR(EXTRACT(minute FROM mytimestamp) / 15)*15

seselect max(mytimestamp) as time, sum(mymetric) as bytes
from metrictable
where mymetric > ( select max(mymetric) from metrictable) - (1/96)


"mytimestamp" is a timestamp data type. I want to get a sum for every 15 minute interval in the table. I will add a where clause to limit how far back I want to go. The where clause I have there now is just an example. tried group by, group by rollup, analytic with a window.
do i need the model clause? I have never used that. I really do think there is 
a way to do this in straight sql. Been working on it for a while....
