Subject Numeration without hole, Is right Before Insert Trigger?
Author Luigi Siciliano
I must assign a serial number, without hole, in a column of a fiscal
I must assign the number only when I know if the document is complete
and I think the right moment is on a Before Insert Trigger for the table.

Is right or the insertion can fail? If not right, when I must assign the
number to be sure of not have a hole in numeration?
