list-xiugaisave.asp 代码：
<%
set conn=server.createobject("adodb.connection")
conn.open "driver={microsoft access driver (*.mdb)};dbq="&server.mappath("test.mdb")


exec="select * from test where id="&request.form("id")
set rs=server.createobject("adodb.recordset")
rs.open exec,conn,1,3
rs("aa")=request.form("aa")
rs("bb")=request.form("bb")
rs.update
rs.close
set rs=nothing
conn.close
set conn=nothing
response.redirect "list.asp"
%>


Description: [Microsoft][ODBC Microsoft Access Driver] 语法错误 (操作符丢失) 在查询表达式 'id=' 中。


该如何修改 谢谢各位！

<input type="hidden" name="id" value="<%=rs("id")%>">

试试
id=request.querystring("id")
sql="select * from test where id="&id&""

把这也用同样的方法也改过来
exec="select * from test where id="&request.form("id")
