you cannot do it with ALL
but you can do it with one script:


here is the short one:

set termout off
set feedback off
set heading off
set trimspool on
set linesize 200
set pagesize 0

spool revoke_all.sql

select 'revoke all on ' || table_name|| '  from <user_name> ;' from all_tables where owner not in ('SYS', 'SYSTEM');

spool off
@revoke_all.sql


save this in a file , say test.sql

and call this file in sqlplus

SQL> @test.sql



that will be it

The above solution will work fine. Another way to do this would be with a PL/SQL block

declare
  user_name varchar2(30) := 'SCOTT'; -- the name of the user that you like to revoke privileges from
begin
  for rec in (select table_name
                 from all_tables
                 where owner not in ('SYS','SYSTEM')) loop
    execute immediate 'revoke all on '||rec.table_name||' from '||user_name;
  end loop;
end;

hi there

well u can use a pl/sql block to solve ur problem for all the users. well what ora-dba has given , u have to hard code the username.

u can go by seazodiac method since it will be easy to do it.
also u can get the username at runtime also.

regards
annamalai

Dear annamalai,
you can easily change my code so that the username doesn't have to be hard coded:

define user_name = "SCOTT"

begin
  for rec in (select table_name
                 from all_tables
                 where owner not in ('SYS','SYSTEM')) loop
    execute immediate 'revoke all on '||rec.table_name||' from &user_name';
  end loop;
end;
