<br /> 通过<a class="link_keyword" href="http://www.qqread.com/keywords/jsp.html" target="_blank">jsp</a>实现对数据的批量更新<br />
<br />
我这有一个程序，不知能不能帮到你！！ <br /><-- <br />
这是a1.jsp页面程序 <br />
--> <br /><table border="0" align="left" class=ppc_download_ad_frame cellspacing=0 cellpadding=0 width="1%" style="margin-top:10px;margin-right:7px;margin-bottom:3px;margin-left:0px">
<tr>
<td id=a><img height=9 width=9></td>
<td id=b width="100%"><img height=1 width=1></td>
<td id=c><img height=9 width=9></td>
</tr>
<tr>
<td id=d><img height=1 width=1></td>
<td id=e valign=top height="100%"><!-- frame contents -->
<table cellspacing=0 cellpadding=0 border=0>
<tr>
<td><div id="w_hzh"></div></td>
</tr>
</table>
<!-- /frame contents --></td>
<td id=f><img height=1 width=1></td>
</tr>
<tr>
<td id=g><img height=9 width=9></td>
<td id=h><img height=1 width=1></td>
<td id=i><img height=9 width=9></td>
</tr>
</table><jsp:useBean id="pool" scope="page" class="sql_link.sql_link"/>//引用<a class="link_keyword" href="http://www.qqread.com/database/" target="_blank">数据库</a>连接bean <br /><html> <br /><head> <br /><link rel="stylesheet" type="text/css" href="main.css"> <br /><title>Untitled</title> <br /></head> <br /><body> <br /><form name=f1 action="a2.jsp" method="post"> <br /><table> <br /><%ResultSet rs = null; <br />
int i=0; <br />
rs=pool.Query("select id,姓名,性别 from 数据库名"); <br />
while(rs.next()) <br />
{ <br />
i++; <br />
String tax="ta"+String.valueOf(i); <br />
String tbx="tb"+String.valueOf(i); <br />
String tcx="tc"+String.valueOf(i); <br />
%> <br /><tr> <br /><td> <br /><input type=hidden name="<%=tcx%>" value="<%rs.getInt(1)%>"> <br /><input type=text name="<%=tax%>" value="<%=rs.getString(2)%>"> <br /></td> <br /><td> <br /><input type=text name="<%=tbx%>" value="<%=rs.getString(3)%>"> <br /></td> <br /></tr> <br /><% <br />
} <br />
%> <br /><input type=hidden name=hh value="<%=i%>"> <br /></table> <br /></form> <br /></body> <br /></html> <br />
//------------------------------------------------------------------------------ <br />
//a2.jsp接受从a1.jsp页面传过来的数据并存入数据库！！ <br /><jsp:useBean id="pool" scope="page" class="sql_link.sql_link"/>//引用数据库连接bean <br /><html> <br /><head> <br /><link rel="stylesheet" type="text/css" href="main.css"> <br /><title>Untitled</title> <br /></head> <br /><body> <br /><% <br />
int key=integer.parseInt(request.getParameter("hh")); <br />
for(int i=1;i<=key;i++) <br />
{ String tax="ta"+String.valueOf(i); <br />
String tbx="tb"+String.valueOf(i); <br />
String tcx="tc"+String.valueOf(i); <br />
int id=Integer.parseInt(request.getParameter(tcx)); <br />
String xm=request.getParameter(tax); <br />
String xb=reqquest.getParameter(tbx); <br />
pool.Update("update 数据库名 set 姓名=´"+xm+"´,性别=´"+xb+"´ where id="+id+""); <br />
} <br />
pool.close(); <br />
%> <br /></body> <br /></head> <br />
//这样就ok了！
</div>
</div>
