What about the holding of a value in a table and doing a raw row fetch and if on committal there is a conflict alert user to change?

hmm, I would have a look at the primary keys.
those are ensured by EOF and the DB to be unique, so any number which is

No. Primary keys are not guaranteed to be in sequence without "holes". You may use a stored procedure or something like that to increment a counter - beware of rollbacks.


If there is no requirement for a real sequence without holes, pk may work. Or, depending on the database, any mechanism that can be used for integer pk generation.
