sorry -- if you follow the links from the URL I provided in the previous answer,
you eventually end up in the OracleR Database Data Cartridge Developer's Guide
and there, in chapter 11:
http://download-uk.oracle.com/docs/cd/B19306_01/appdev.102/b14289/dciaggfns.htm#
sthref488
you'll see complete coverage (including an example) of how to do it. but I guess
you folks figured that out yourself already -- after all, the Oracle
documentation is your biggest friend and best source of information -- right?
:-)
cheers,
Lex.

Subject: Instead of SUM() I require MULTIPLY
I just came up with a function I would like, but don't think exists.
TABLE TEST (X NUMBER)
=====================
2
2
4
select sum(x) from test;
will return 8...
what I need is
select multiply(x) from test;
will return 16, because 2*2*4 is 16.
Anyone ever seen a SQL aggregate function like this? I don't think it exists but
I hold out hope.
