This procedure enables to drop any object in an Oracle database if you have the rights for it. It will give you a clean spool file -- no ORA-00942 messages -- when installing or dropping objects where you are not sure if they exist or not. This produces no error messages even if the object does not exist. It may be useful when looking for any other errors in big spool files after installing hundreds of tables, views, packages, etc. The script has been tested on v. 8.1.7. 
create or replace procedure dropObject (ownerName in varchar2, objectName in varchar2) is 

  
  cursor C1 is 
  select 'DROP '||o.object_type||' "' || o.owner || '"."' || o.object_name ||'"' 
    from sys.dba_objects o 
   where o.owner       = ownerName 
     and o.object_name = objectName ; 

  DDL_CURSOR integer; 
  ddl_statement varchar2(500); 

BEGIN 

 DDL_CURSOR := dbms_sql.open_cursor; 
 OPEN C1; 

 LOOP 

   FETCH C1 INTO ddl_statement; 
   EXIT WHEN C1%NOTFOUND; 
   dbms_sql.parse(DDL_CURSOR, ddl_statement, dbms_sql.native); 
     
 END LOOP; 

 dbms_sql.close_cursor(DDL_CURSOR); 
 CLOSE C1; 

END;
