Re: *****SPAM***** Re: if-clause to an exiting statement

Scott hi,

I know it does not sound logic however I do need to set the row count
to 1 in case row count returns 0 , can you show how to add that case
clause and dummy line in my below code ?

SELECT a.eventuei AS _eventuei,
a.nodeid AS _nodeid,
a.ipaddr AS _ipaddr,
now() AS _ts
FROM events a
WHERE
a.eventuei='uei.opennms.org/comns/backup-success-trap' AND
(eventcreatetime > now() - interval '10 minutes')

Thanks !!!!
