Not sure if you've gotten far on your solution, but you may want to have a look at a Oct 27, 2006 posting titled "concatenating historical records" in the comp.databases.ibm-db2 group. In it, I mentioned two solutions I know of: one uses a recursive CTE (in Oracle you can add SYS_CONNECT_BY_PATH to this mix--see page 122 of Anthony Molinaro's _SQL Cookbook_, published by O'Reilly), and the other uses the XMLAGG function.
