unfortunatly i can not do so because drop the database need an exclusive access to it :(

on the other way, i thing about storing all the data on a different server / database. but now is it possible to do from stored procedure

For
Select

from
OtherServer:OtherDatabase TableStat
GROUP BY
xxx
DO begin
Update AggregateTable set ....
END
