The current issue of "Oracle Magazine" has an article on creating
custom aggregate functions, which naturally got me thinking about how
to do this in DB2.
I found some articles on creating custom aggregate functions in DB2,
written close to three years ago by Knut Stolze:
http://www-128.ibm.com/developerwork...309stolze.html
Mr. Stolze says in the first article that "[c]urrently, there is no
direct way to implement your own user-defined aggregate function." I'm
wondering if this still represents the state-of-the-art, or if there is
now (or will be in V9) a non-Java way to do it.
