Hi Nicolas,
In old releases of Cloudscape, customers were able to create their own
aggregates. This functionality was removed from Derby probably because
the syntax was considered non-standard. Most of the machinery for this
feature is still in the code and it should be easy to re-enable once we
agree on acceptable syntax. I have logged enhancement request 672 to
track this issue.
Regards,

Hi
I wonder how I can create an aggregate function like count or max ?
The idea is i want to process in the same time a list of row and
return something.
For example, I need to get from a list of flights (rows of table
flight) the average delay.
Is it possible in Derby and how ?
Thank you
Nicolas
