Hi,

I am using oralce 10gR1 on windows.I have a user with the name of "HRMS" has system privilege.

SQL> select * from dba_sys_privs where grantee='HRMS';

GRANTEE PRIVILEGE ADM
------------------------------ ---------------------------------------- ---
HRMS CREATE TRIGGER NO
HRMS CREATE PROCEDURE NO

And want to revoke alter table rights from this user.In above command it has only two privilege but this user can do alter table.Please tell me how i restrict this user. one thing is more this is schema user.


Thanks
