java调用存储过程和函数

存储过程:有参数

    String rSet=null;
    CallableStatement cStatement=null;
    try {
       cStatement=connection.prepareCall("{Call sellTicketPROC(?,?,?,?,?,?,?)}");
       cStatement.setString(1, lineID);
       cStatement.setString(2, beginStation);
       cStatement.setString(3, endStation);
       cStatement.setString(4, date);
       cStatement.setString(5, TrainNum);
       cStatement.setString(6, seatTyle);
      cStatement.registerOutParameter(7,Types.VARCHAR);
       cStatement.execute();
       rs=cStatement.getString(7);//得到输出结果

调用函数:

sql="{?=call function_test(?,?)}";
st.registerOutParameter(1, Types.VARCHAR);
cStatement.setString(2, lineID);
cStatement.setString(3, beginStation);
