Aggregation according to multiple criteria at once

Hello to Everybody, I'm doing an averaging over one column using some specific range in another column multiple times. Actually the query looks like: select avg(value) from myTable where time<N and time>M. i'm calling that query from the python script multiple times. Can i call the query once in order to reduce the number of requests to the monetDB?
