Hi all,
I have three questions about 1 table CREATE TABLE public.logs ( rule_name varchar(32) NOT NULL, bytes int8 NOT NULL, pkts int8 NOT NULL, hostname varchar(100), that_time int4 NOT NULL ) WITH OIDS; Question 1. If I run the following query: select cast(min(that_time) as abstime), cast(max(that_time) as abstime), (sum(bytes)/(1024*1024)) as "Totaal in Megabytes" from logs where that_time between cast( abstime('2004-10-1 00:00') as int4) and cast( abstime('2004-11-1 00:00') as int4) and rule_name = 'Incoming 83 50 in' or rule_name = 'Outgoing 83 50 out' I expect that the outcome will be between "2004-10-1 00:00" and "2004-11-1 00:00" (the month october). However, I get the following result: min max Totaal in Megabytes "2004-09-01 00:00:01+02" "2004-11-23 11:50:01+01"; "82768.623353004456" The min date is the date of the first entry ever, the max entry the last entry ever. Why is this? Question 2. If I refrase the above query to: select cast(min(that_time) as abstime), cast(max(that_time) as abstime), (sum(bytes)/(1024*1024)) as "Totaal in Megabytes" from logs where rule_name = 'Incoming 83 50 in' or rule_name = 'Outgoing 83 50 out' and that_time between cast( abstime('2004-10-1 00:00') as int4) and cast( abstime('2004-11-1 00:00') as int4) I get a diffent answer (see the Totaal in Megabytes): min max Totaal in Megabytes "2004-09-01 00:00:01+02" "2004-11-23 12:00:01+01" "92406.078444480896" My question why is this? Question 3. Querying for just "rule_name = 'Incoming 83 50 in'" gives 34990 Megabytes, just querying for "rule_name = 'Outgoing 83 50 out'" gives 5524 Megabytes. How does that compare to the queries above? Groeten, Joost Kraaijeveld Askesis B.V.
