Title:
Enforce unique and not null
Hi all, I have a concern with vfp. After working several years with vfp tables I have had duplicate and null records even I have asked for unique and not null in my table definition. By the way, i use mostly free tables.
1. Why this does not work ?
2. how can this be enforced ?
Thank you all
Norman Avila
