I have the following query:

src_ip, src_cc, dst_ip, dst_cc, signature, signature_id, ip_proto
ORDER BY maxTime DESC LIMIT 5000
The part that is causing the strange result is probably this:
AND (map1.cc != 'US' OR map2.cc != 'US') AND (map1.c_long != 'US' OR
map2.c_long != 'US')
the value could be 'US' or 'UNITED STATES' depending on user input so
I check both table fields against their input.
On my system (fbsd 5.1.48) 'US' is not shown, on another system (linux
5.1.54), 'US' appears in the results.
Is there a better way to write this?
Is this what you mean?
SELECT
COUNT(signature) AS count, MAX(timestamp) AS maxTime, INET_NTOA(src_ip),
map1.
cc as src_cc, INET_NTOA(dst_ip), map2.cc as dst_cc,
signature, signature_id, ip_proto
FROM event
LEFT JOIN mappings AS map1 ON event.src_ip = map1.ip AND map1.cc != 'US' AND
map1.c_long != 'United States'
LEFT JOIN mappings AS map2 ON event.dst_ip = map2.ip AND map2.cc != 'US' AND
map2.c_long != 'United States'
WHERE timestamp BETWEEN '2011-10-11 03:00:00' AND '2011-10-12 02:59:59'
GROUP BY src_ip, src_cc, dst_ip, dst_cc, signature, signature_id, ip_proto
ORDER BY maxTime DESC LIMIT 5000

Is it OK to keep adding to those joins?
Sure. At some point, though, you might consider an intermediate table to
precompute/hide some of the complexity.

In a view there could be say
50 countries. The user can keep on adding more to exclude. So would I
just expand on the ANDs like so:
AND map1.cc !='CA' AND map1.cc !='US' AND map1.cc !='LV'... ?
