Al,
Sounds as if you solved it, but:
I agree with the others that you want to get everything in shape before appending to SQL Server. In your shoes I'd use SELECT expressions into a new cursor, eg
select EVL(DateTimeColX,.NULL.) as DateTimeColX, ...
(but watch out if the very first value is blank or VFP will throw a "cannot determne field type" error) and then append from that cursor. Also, if rows are safe I'd look at the tablebuffering since SQL Server needs lots of room for database log if it's all one fat append.

"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
