Hi all,
Is there any way to find whether a logged in user is a sysdba o not?
I used the following to connect to the db:

OracleConnection oraConnection = new OracleConnection();
            string conString = @"Data Source =orcl;User Id =test;Password =test";
            oraConnection.ConnectionString = conString;
            oraConnection.Open();

Please guide me through this matter.
