大家帮我看看,这段修改代码,为什么老是不执行

[grand777]

<% dim action,e_id
action=request.QueryString("action")
action=request.QueryString("e_id")

select case action
case "update"
set rs2=server.CreateObject("adodb.recordset")
rs2.open "select * FROM dbo.e_yielder where e_id='"&e_id&"'", conn,1,3

rs2("parentid")=trim(request("parentid"))

rs2.Update
response.Write "<script language='javascript'>alert('修改成功');history.go(-1);</script>"
rs2.close
set rs2=nothing
end select
%>

一点修改,过来就显示一个空白页面,没有执行完,不知道是什么地方错了

[tokilcoom]

rs.addnew
rs("key")=**
rs.update

[tokilcoom]

或者用update xx set a=**,b=** where id=**

[hz890]

action=request.QueryString("action")
action=request.QueryString("e_id")
应改为：
action=request.QueryString("action")
e_id=request.QueryString("e_id")
action 怎么能重复赋值呢？

<% dim action,e_id
action=request.QueryString("action")
e_id=request.QueryString("e_id")


set rs2=server.CreateObject("adodb.recordset")
rs2.open "select * FROM dbo.e_yielder where e_id='"&e_id&"'", conn,1,3
select case action
case "update"
rs2("parentid")=trim(request("parentid"))
rs2.Update
response.Write "<script language='javascript'>alert('修改成功');history.go(-1);</script>"
end select
%>

e_id 是字符串还是编号呀? 代码这样写是编号哦.
