Manage view access to tables within the same database

Applies to: ✅ Microsoft Fabric ✅ Azure Data Explorer

Principals gain access to resources, such as databases and tables, based on their assigned security roles. The viewer security role is only available at the database level, and assigning a principal this role gives them view access to all tables in the database.

In this article, you learn methods for controlling a principal's table view access.

Structure data for controlled access

To control access more effectively, we recommend that you separate tables into different databases based on access privileges. For instance, create a distinct database for sensitive data and restrict access to specific principals by assigning them the relevant security roles.

Restricted View Access policy

To restrict access to specific tables, you can turn on the Restricted View Access policy for those tables. This policy ensures that only principals with the unrestrictedViewer role can access the table. Meanwhile, principals with the regular viewer role can't view the table.

Row Level Security policy

The Row Level Security (RLS) policy allows you to restrict access to rows of data based on specific criteria and allows masking data in columns. When you create an RLS policy on a table, the restriction applies to all users, including database administrators and the RLS creator.

Create a follower database

Create a database shortcut in Fabric and follow only the relevant tables that you'd like to share with the specific principal or set of principals.
