Is it possible via script/tool to generate authomatically many delete statements based on the tables fk relations, using Oracle PL/SQL?

In example: I have the table: CHICKEN (CHICKEN_CODE NUMBER) and there are 30 tables with fk references to its CHICKEN_CODE that I need to delete; there are also other 150 tables foreign-key-linked to that 30 tables that I need to delete first.

Is there some tool/script PL/SQL that I can run in order to generate all the necessary delete statements based on the FK relations for me?

(by the way, I know about cascade delete on the relations, but please pay attention: I CAN'T USE IT IN MY PRODUCTION DATABASE, because it's dangerous!)

I'm using Oracle DataBase 10G R2.

This is the result I've written, but it is not recursive:

This is a view I have previously written, but of course it is not recursive!

... and it contains the error of using DBA_CONSTRAINTS instead of ALL_CONSTRAINTS...
