hey guys

I'm trying to use ip2country technique to show my users'flags

simple thing to do is to write a sql statement and show users from session table and then query to see if their ip is in what range and show their flags

it simple but dengerous becuase when showing 300 users online and fetching from session table and then query once again ip2country table to get the flags there will be surelly memory overusage problem

now i wrote a query to make it in one query :

SELECT s.session_ip,ipc.* FROM session s
    left join ip2country ipc ON ipc.ip_lo<=s.session_ip AND ipc.ip_hi>=s.session_ip
    WHERE s.session_time  > '".( time() - 60) )."' 

now its clear above query is wrong cause ips saved in ip2country table is long string 1000013824 and ips saved in session table are real ip e.g. 193.169.0.0

now i know how to convert from ip to long in php ip2long() but is there any command in mysql to do it with out building another query !?
