Copy rows from the same table and update the ID column

Question

I have the following table

I have inserted Product B to it and it gives me an ID of 15

Answer 1

insert into Table (DefID,ProdID,Definition,Desc)
       select DefID,15,Definition,Desc from Table where vo_user='jloe';

Answer 2

INSERT INTO ProuctDefinition (ProdID, Definition, Desc)
SELECT
  xxx, Definition, Desc
FROM
  ProductDefinition
WHERE
  ProdID = yyy

The xxx is your new ProdID and the yyy is your old one. This also assumes that DefID is automagically populated on INSERT.
