Re: assistance on self join pls

Dear Darren,

Your question is not very clear to me.

On what columns do you want to aggregate?

suppose u want to aggregate on outsite and inside ip
you shud group by those columns and run a aggregate function
like sum or avg etc , suppose u want the total traffic for
every pair you can do this:

select  inside_ip,outside_ip , sum(outbound_bytes) as total_traffic from
connection_data group by inside_ip,outside_ip ;

Hope it helps.
