A quick and dirty trick would be to have a normal auto-increment field and, after insert, compute "case" and update the insert.


where f is your function.

Problem with that is that I want to have more control on case#. So if
this case is from A source the auto increment starts at case# 3000 and
if its from source B auto increment starts with case# 4000.
