A typical application for low numbers (not letting them increase over time) is the "human readabilitly" if you need them outside the DB as labels on boxes for "real life transactions". One solution is writing a function using a self join on the column on a.n + 1 = b.n searching for NULL results; then returning the a.n+1. I have this somewhere in the jungle of my source code snippets. Tell me if you need me searching for it :) Emil
