Access to DB records via a primary key for portal users

Access to DB records via a primary key for portal users

Hi,
I'm a potential new user of Zoho Creator. Is it possible to identify Portal users so each user can only access records with their primary key in the db? There are relationships between many tables also so this access limitation must carry through the entire application. The database was created by migrating it from MS Access into Zoho Creator - ive tried it with a sample db and it looks ok but the Queries are all lost and the forms are lost??

Does migrating a large DB from MS Access also import the Access Reports, Queries Tables and ALL relationships? This is critical to me subscribing to use Zoho The ability to allow Portal (read Only) access and Access Limitation by User Primary-key is the main reason we need this type of solution.

Any help appreciated.
