[求助]为什么只可以读取ACCESS的数据，却写不进去
这是reg.asp的代码：<!--#include file="conn.asp"-->
<%
if request("action")="reg" then
set rs=server.createobject("adodb.recordset")
rs.open "select * from user where name='"&trim(request("name"))&"'",conn,1,1
if rs.recordcount>0 then
response.write "<script language='javascript'>window.alert('您输入的用户名已存在，请返回重新输入！');history.back(-1);</script>"
response.end()
end if
sql="select * from user"
set rs=server.createobject("adodb.recordset")
rs.open sql,conn,1,3
rs.addnew
rs("name")=trim(request.form("name"))
rs("pwd")=trim(request.form("pwd"))
rs("wenti")=trim(request.form("wenti"))
rs("daan")=trim(request.form("daan"))
rs.update
rs.close
set rs=nothing
response.write "<script language=javascript> alert('注册成功，点击确定立即登录！');location.replace('login.asp');</script>"
response.end
end if
%>
