Thanks again, Jackson, but your query is not right :(
Here is a sample output:
your query:
SELECT o.origine, sum(o.bytes), sum(d.bytes), '09/02/1999
00:59:59'::datetime
FROM day o, day d
where o.origine=d.destinazione
and o.origine << '194.74.133.0/24'
and o.when between '09/02/1999 00:00:01' and '09/02/1999 00:59:59'
and d.when between '09/02/1999 00:00:01' and '09/02/1999 00:59:59'
GROUP BY o.origine,4;
result (only for host 194.74.133.11, query is too long):
194.74.133.11|18569856|13493249|09/02/1999 00:59:59.00 MET
simple query to check first sum:
SELECT o.origine, sum(o.bytes)
FROM day o
where o.origine = '194.74.133.11'
and o.when between '09/02/1999 00:00:01' and '09/02/1999 00:59:59'
GROUP BY o.origine;
194.74.133.11|250944
Huge difference! Moreover, your query is slow, much much slower than two
separate queries. I would have used it though, if it worked. Postgresql
keeps crashing on my loop. :(
Thanks
