I've built an app very similar to the jumpstart sample app, but when I close the data maintenance form and choose to save my changes, I get this message:

Dynamic SQL generation for the UpdateCommand is not supported against a SelectCommand that does not return any key column information.

This is the SQL Statement being called in the Biz object:
SELECT * From lkup_caregivers WHERE ID = " + careGiverID.ToString()

Can someone tell me which step I missed?

Thanks,
Mike
