    {
      IDictionary<int, string> TEMP = new Dictionary<int, string>();
      oConHandler = new CConnectionHandler();
      try
      {
        oCommand = new OracleCommand(Q_SELECT_ALL_FROM_TABLE(membercode, status), oConHandler.OpenConnAkses());
        oCommand.ExecuteScalar(); // Execute sql syntax
       //-- load into Idictionary 
      //-- How can i do that ???

      }
      catch (Exception ex)
      {
        olog.WriteLogFile("Error while execute load_data_temp_msgs at : " + DateTime.Now.ToString() + "\n" + "Reason : " + ex.Message);
      }
      finally { oConHandler.CloseConnAkses(); }
      return TEMP;
    }

C#

private string Q_SELECT_ALL_FROM_TABLE(string membercode, string status)
{
   string Q_SQL = "SELECT * FROM T_MEMBER WHERE BANKCODE='" + membercode + "' AND STATUS='" + status + "'";

   return Q_SQL;

I don't believe you want to use ExecuteScalar for this. Execute scalar will only return a single value (first column of first row of dataset with everything else being ignored). I think ExecuteReader is what you want.

I think something like this might work:

using(OracleDataReader reader = oCommand.ExecuteReader())  //Instead of oCommand.ExecuteScalar;
{

   while(reader.read)
   {
      TEMP.Add(Convert.ToInt32(reader.Item("{the name of column containing int value}"),reader.Item("{the name of column containing string}").ToString());
   }
}
