이걸 어떻게 표시해야 하나요?
bbs/current_connect_ss.php?gr_id=그룹아이디 이런식으로는 안되던데.

select a.mb_id, b.mb_nick, b.mb_name, b.mb_email, b.mb_homepage, b.mb_open, b.mb_point, a.lo_ip, a.lo_location, a.lo_url from g4_login a left join g4_member b on (a.mb_id = b.mb_id) where a.mb_id <> 'typemoon' and a.mb_id in (select mb_id from g4_group_member where gr_id = 'ss') order by a.lo_datetime desc

1064 : You have an error in your SQL syntax. Check the manual that corresponds to your MySQL server version for the right syntax to use near 'select mb_id from g4_group_member where gr_id = 'ss')

error file : /bbs/current_connect_ss.php

이런 에러가 뜨는데 mysql 버전 문제인가요?

5.0.45 버전인데 이상하군요.
뭔가 잘못 적용한 곳이 있으려나요...

뭐가 문제인지 모르겠군요.
아무튼 답변 감사합니다.^^
