how to handle parent-child hierarchy in db2 udb V9.5

Hi Gurus,

I need to archive data from all child tables before deleting/archiving data from parent table. I can find out the hierarchy of tables through syscat.references and CTE. I need to prepare insert statements like "insert into archive.child table from select * from schema.child where..." for the child at leaf node and traverse upto the highest level in the hierarchy. Can someone please advise how is it possible in db2 udb?

I have something like: A is parent of B and C. C is parent of D. D is parent of E and F. Before deleting/archiving data from A, I need to prepare statements to archive data from E and F and then go upto A.

Any help is highly appreciated.
Sam.
