Subject Generator
Author Robert F. Tulloch

Given an existing table, I need to a field to contain a unique
number and thereafter when inserting a record, use a generator to
get the unique number.

I added a new field (not unique for now). I want to populate it
with numbers from a generator. Can this be done with an existing
table? Or just write a statement to fill the field with
incrementing numbers, then set the generator start to the next
sequential number?
