hi
thanks for the response.
the code drops the users.
but i want to retain the users,
and the tables of the users alone has to be deleted. so that i can use the user names again.

Replace MAG% with your USER%
COMMENT OF dbms_output i you dont want (if you prefer to have it,
make sure you have set serveroutput on and dbms_output.enable('100000000') or any high value)

 1  declare
  2  cursor c1 is select owner,table_name from dba_Tables where owner like 'MAG%' order by owner;
  3  begin
  4  for mag in c1 loop
  5  exit when c1%notfound;
  6     execute immediate ('drop table '||mag.owner||'.'||mag.table_name||' cascade constraints');
  7     DBMS_OUTPUT.PUT_LINE ('drop table '||mag.owner||'.'||mag.table_name||' cascade constraints');
  8  end loop;
  9* end;
mag@mutation_mutation > /
drop table MAG.DEPT cascade constraints
drop table MAG.EMP cascade constraints

It's (most probably) a permissions issue. Your access to DBA_ views has been granted through a role. In order to use it in a procedure the grant should be done directly to the user. Look here for more info, or search the board. It's a frequent issue.

Same cause/action. SYSTEM is no dictionary owner, he has been given grants through DBA role. Read my previous post.
