[Quoted] Does the suggestion of assigning the primary key from a sequence via a pre-insert trigger guarantee no gaps in sequence numbers, or does it help cut down on the quantity of gaps? Ultimately, if you cannot tolerate any gaps at all I fail to understand how deferring acquisition of a sequence number to a pre-insert time will stop the wasting of this number should a rollback be done.

I've been wrong before... corrections humbly requested.
