Delete from dba_objects

Question

My database version is Oracle 10.1.0.2.0.
I logon as a ABC schema and by mistake I ran @catproc.script.
Now its created so many unwanted objects under that Schema (abc).
Now I wanted to delete all unwanted objects from abc schema.
Most of the unwanted objects starts from DBMS.
I can delete manually one by one from dbconsole.
But it takes long time (almost 200 objects need to delete).
My question if I delete from dba_objects as below.
will it delete all objects under abc schema starts with DBMS?
Is it correct way to do it?
delete from dba_objects
where owner = 'ABC' and OBJECT_TYPE ='PACKAGE'
and object_name like 'DBMS%';

Answer 1

There are probably objects created under the ABC schema that do not start with DBMS. To ensure that you get all objects created by catproc.sql, you could do something like:
SELECT 'DROP ABC.'||object_type||' '||object_name||';'
FROM (SELECT object_name, object_type
      FROM dba_objects
      WHERE owner = 'ABC'
      INTERSECT
      SELECT object_name, object_type
      FROM dba_objects
      WHERE owner = 'SYS')
WHERE object_type NOT IN ('PACKAGE BODY', 'TRIGGER', 'INDEX', 'LOB')As with all scripts generated from the data dictionary, check it carefully before you actually run it.
