Why on earth.... Until you wrote what you did in response to Charlotte, hers is exactly the solution I imagined.... A user has a security level, and the record has a security level, and any time a user has a security level above that required for the record, they can see it. You need joins to the user privileges table. I don't get the not updatable part. I am not much good with that aspect, I believe it is handled through relationships. Dunno - but quality databases do it all the time. Absolutely, users never see the table. Only a view prepared for them. -----Original Message----- From: accessd-bounces at databaseadvisors.com [mailto:accessd-bounces at databaseadvisors.com] On Behalf Of Non-Linearly Sent: Sunday, March 18, 2012 4:03 AM To: 'Access Developers discussion and problem solving' Subject: Re: [AccessD] Split table's records according to user acoount Thank you very much, so in the worst case I need so many levels of security as there are users... (although in this worst case that I do not have overlap then it will the same to assign each record with a user account).
