                one.add(rs.getString(10));
                one.add(rs.getInt(11));

    }

我试图展示结果的页面

<%
SearchDAO searchDAO = new SearchDAO();
ArrayList all = searchDAO.viewAllDrivers();
int size = all.size();
%>


<table width="95%" align="center"  style="border:#D22929 solid 2px;padding:10px;" border="0">
  <tr>
    <th bgcolor="#D22929" scope="col"><span class="style10">Driver Name </span></th>

    <th bgcolor="#D22929" scope="col"><span class="style10">Ation</span></th>
  </tr>

<%
for(int i=0;i<size;i++){
ArrayList one=(ArrayList)all.get(i);
%>
<tr style="height:30px; padding:4px;">
    <td><div align="center"><%=(String)one.get(1)%></div></td>
    <td><div align="center"><%=(String)one.get(2)%></div></td>
    <td><div align="center"><%=(String)one.get(3)%></div></td>
    <td><div align="center"><%=(String)one.get(4)%>&nbsp;</div></td>
    <td><div align="center"><%=(String)one.get(5)%>&nbsp;</div></td>

</tr>
<% } %>

推荐答案

此错误意味着您的 adddriver 只有 6 列，因此 8 是无效的列索引.

This error implies that your adddriver only has 6 columns, so 8 is an invalid column index.

这意味着所有这些语句都有无效的索引:

This means all of these statements have invalid indices :

            one.add(rs.getString(8));
            one.add(rs.getString(9));
            one.add(rs.getString(10));
            one.add(rs.getInt(11));

也许您的数据库表不包含您认为的内容.

Perhaps your DB table doesn't contain what you think it does.
