following is what i ran in sql+

try
select * from e1 where fname like '%'+sys_context('userenv', 'session_user')
+'%';
I suspect the string SYS_CONTEXT returns is not only 'SYSTEM' but with some other
empty spaces.

thanks for your advice. i think i found the problem. it's
not what sys_context returns contains empty spaces but the
fname in e1 contains empty spaces. i will try more. thanks
again.
