Hello,
[I sent this email off yesterday, but didn't appear to make it to the list. Hope nobody gets this twice :(]
I have a rule that I've been trying to run against a certain table, but it always spits out blank rows, in addition to the rows I want.
I have Apach logging to a postgresql 7.3 database with each parameter seperated by a |. I then create a rule to seperate these logs into more logical columns, like this:
create rule split_log as on insert to messyTable where message like '%website.url%' do insert into cleanTable values (
split_part(syslogtb.message,' | ',1),
split_part(syslogtb.message,' | ',2),
.....
split_part(syslogtb.message,' | ',n)
);
where n is the number of parameters Apache logs.
Without the rule, everything gets properly inserted into mesyTable. I want to rule in place to seperate out the information. But the rule produces a cleanTable that contains the expected stuff, but it also contains duplicates of that stuff, and several empty rows. Is there any obvious way to avoid either?
Thanks!
