No, no, you're missing missing my point.

My question was; Assuming all fields on a record are optional, and the Id is auto-incremented,
then what is left to INSERT in the SQL command?

I'm trying to create a generic AddRecord method that gets called whenever the user clicks
the Add Record button, but that adds another twist; in a generic method, you won't know what
data to insert to create a new record.

I used to use:
nNewId = GetNewPrimaryKey()
INSERT INTO MyTable (Id) VALUES (nNewId)
But now since the Id is auto-incremented, there is really no way to use a SQL INSERT
command.

In addition, an integer field is not for irrational people
