Hi all,
I've just bumped into a need to maintain a sequential numbering of
database rows, which are created by more concurrent WO application
instances.
Whilst I can think of a number of possible solutions, I'd like to ask
for your experience before implementing one? Strangely enough I
haven't done this yet, and thus can't well estimate the advantages and
disadvantages of different possible approaches (locking, UNIQUE
column, etc...) and their respective gotchas.
Thanks,
