string sqlCmd = @"SELECT r.row_id AS resp_id,
                         r.name AS resp_name
                  FROM srb.s_resp r,
                       srb.s_per_resp pr,
                       srb.s_contact c,
                       srb.s_user u
                  WHERE r.row_id = pr.resp_id
                    AND u.row_id = c.row_id
                    AND c.person_uid = pr.per_id
                    AND UPPER(u.login) = @login
                 ORDER BY r.name";

OracleConnection con = new OracleConnection(getConnectionString(username, password));
OracleCommand command = con.CreateCommand();

conSiebel.Open();
command.CommandType = CommandType.Text;
command.Connection = con;
command.CommandText = sqlCmd;

command.Parameters.Add(new OracleParameter("login", username));

IDataReader reader = command.ExecuteReader(CommandBehavior.CloseConnection);
reader.Close();

我试图将@login参数添加到上述查询中，但未添加，有人可以帮助我解决此问题吗？
