Easiest way I've found is to read NextVal on the relevant sequence, and use
the value you get for the key field.
Since the field will be loaded, the "default" function that assigns the
number, kind of like an Access Autonumber - will *not* override the value
you manually insert.
So:
Get nextval on sequence
.addnew
recordset!idfield = thenextvalyougot
