Do you want to support either of those in production? Get support calls and/or enhancement requests for same?

I have experience with non-trivial systems which have put business logic in database stored procedures. They were not pretty. One example was a single stored proc having north of 40 parameters and was central to a high-volume transaction workflow.

That is how I learned at the time Oracle had a max of 4 threads available to stored procs and that SGA usage can reach out and bite you in "fun and interesting" ways.
