One thing I have tried is
Set Generator to 0
Select Gen_ID(GEN_Name,(Select max(ID) from TABLE)) from rdb$Database
The select statement forces the update of the generator value by Max(ID)
from table. RDB$Database is used because it has one record and I only
want to increment the generator once by max(ID)
