Most BI tools like Oracle's OBIEE and SAP's BOXI have a way to configure a data source where a database stored procedure can be called to initialise the database context. So the logged-in username can be asserted into the database and row-level security can be enforced by the database.
For example in SAP's BOXI, there is a connection property called "ConnectionInit" and you can call a procedure to assert the BOXI username into it: "BEGIN my_database_context.init('@Variable('BOUSER')'); END;".
Can this be done in QlikSense? Please show me how. This is a necessary feature for us to consider a BI product.
