You mean to say.. you need to cleanup the USER. and DON't want to DROP USER (SCHEMA) (USER=SCHEMA)

1. connect to the USER whos objects you want to drop.
2. spool output of following sql

SELECT 'DROP '||object_type||' '||object_name ||';' FROM user_objects

3. and execute statements generated by spool file.

You may get some errors while dropping objects having dependancies.. that u have to take care..

Do you mean the USER must remain after the objects are gone?

One way is to drop the user with the cascade option then recreate it. The other is to write some PL/SQL to identify and drop all the objects doing stuff like:

BEGIN
FOR cur_rec IN (SELECT object_type, object_name FROM user_objects) LOOP
BEGIN
EXECUTE IMMEDIATE 'DROP ' || cur_rec.object_type || ' ' || cur_rec.object_name;
EXCEPTION
WHEN OTHER THEN
NULL;
END;
END LOOP;
END;
/

This may need a bit of work as I've not got a server available to check it at the moment.

Personally, I'd

DROP USER username CASCADE;

and then re-create the user as it was. Quickest and most simplistic.
