关于java,sql问题,急啊!
这是一个获取所有文章标题压栈到Vector里的功能代码.

String   strSql;
ResultSet   rs;

Vector   Topic   =   new   Vector();
Topic   topicform   =   new   Topic();


strSql   =   "select   topicid,topic,level,clicktimes   from   okancn_topic   where  

sortid= "+1   +   "   order   by   time   DESC ";

rs   =   db.OpenSql(strSql);
while(rs.next()){
          topicform.setTopicid(rs.getInt(1));
          topicform.setTopic(rs.getString(2));
          topicform.setLevel(rs.getInt(3));
          topicform.setClicktimes(rs.getInt(4));
          System.out.println( "一次压栈 "+rs.getString(2));
          //压栈
        Topic.addElement(topicform);
}
        topicform   =   (Topic)Topic.get(0);
        System.out.println( "一次 "+topicform.getTopic());
        topicform=   (Topic)Topic.get(1);
        System.out.println( "二次 "+topicform.getTopic());

比如我okancn_topic表里有两条不同记录
打印的结果怎么是 "一次asdfasdf,二次asdfasdf "     (asdfasdf是我的标题)
都是同一个记录,怎么回事啊，

显示一下topicid看看
