How To Use Database Policies / Virtual Private Database (VPD) To Restrict Data In Application and SQL?

Example

As an example, in a Vision environment, the organization Seattle Manufacturing (M1 / id 207) has various subinventories like FGI, Stores, FldSvc, INTRANSIT, FloorStock, etc.

What if you wanted users only access to FGI and Stores? Or some dynamic listing of subinventories by user or responsibility?

Note: In the images below, user details / company name / address / email / telephone number represent a fictitious sample (based upon made up data used in the Oracle Demo Vision Instance). Any similarity to actual persons, living or dead, is purely coincidental and not intended in any manner.

Also note, a database policy would apply to all users in the environment using SQL, forms, reports, and custom programs.

Using database policies is not supported and this is provided as an example. If you hit performance issues or application problems, please disable any custom code to confirm the application still behaves normally. You are responsible for debugging your own custom code and correcting any issues that it causes.
