java调用存储函数，有些数据可以执行成功，有些却报异常是什么原因？

Question

/**
* 获取书籍总点击量
*
* @param bookid 书籍id
* @return 书籍总点击量
* @throws Exception
*/
@Override
public int getClickAllById(int bookid) throws Exception {

    ResultSet rs = null;
    DataParameter[] parameters = new DataParameter[] { 
            adoHelper.getReturnParameter(),
            adoHelper.getParameter("inintbookid", bookid, DataType.INTEGER),
            adoHelper.getOutputParameter("outcurlist", DataType.CURSOR) };

    rs = adoHelper.executeReader(Config.getConfig("bookconnectionstring"), "FN_GETBOOKALLINFOBYID",
            parameters);

    int clickAll = 0;
    if (rs.next()) {
        clickAll = rs.getInt("CLICKRATE_ALL");
    }


    return clickAll;
}


    调用这个存储函数，传入的bookid有些可以执行成功，有些却报异常。异常信息是：
    2015/12/21 16:43:28 | INFO  - MLog                       - MLog clients using log4j logging.

然后我这个做了定时任务，每15分钟执行一次这个程序，定时用的Timer。
数据库用的是Oracle

Answer 1

FN_GETBOOKALLINFOBYID
数据库中有这个函数么？是不是拼写错了。
