            DataSet ds = new DataSet();
            string strSql = string.Format(" select * from student where id={0}",ID);
            try
            {
                IDbCommand command = session.Connection.CreateCommand();
                command.CommandText = strSql;
                SqlDataAdapter da = new SqlDataAdapter(command as SqlCommand);
                da.Fill(ds);
            }
