Hi.
I need to define a synthtic field for a Sequel::Model source dataset. I'd
like getting a sum field with any Model query. How can it be done?
Thank you very much.

It sounds like you want to add a SELECTed expression to the model's dataset:

Our DBA mentioned that he uses LIMIT 0 himself.
But from what I gather in regards to the ORDER BY RANDOM(), its because when
you don't have column that has small gaps between values (such as our pk
UID's), then attaching an order by with a random value can actually help the
query pull a result.
