Security Setup to Restrict SQL Queries of All Fusion Tables

Summary:

We have a custom SQL Query role but it allows users to query all tables across each functional area. However, auditing requirements force us to restrict SQL query access to specific Oracle Fusion functional areas (AR, AP, GL, etc.).

We use SplashBI SQLConnect Tool to query Fusion tables.

Is there a supported way to restrict SQL access to specific modules or schemas?

If module‑level restriction is not supported, what is the recommended best‑practice approach for governance and security.
