I want to create a DB read user and allow him to connect to DB via SQL Developer tool with below restrictions :
User shouldn't be able to query data or DB structure into the box locally and upload to somewhere externally using browser
The challenge we see here is although the read only user doesn't have the ability to export the schema dump but still he can query any table and export the output of that table from SQL developer because thats is a feature of SQL developer. How can I restrict the user to even export the output of a query from SQL developer.
