调ACCESS数据库问题

[zyzhcxx]

我在access的表里设ID为自动编号。
set conn=server.createobject("adodb.connection")
dsn="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=H:\jwc\jwc.mdb;Persist Security Info=False"
conn.open dsn
set rs=server.createobject("adodb.recordset")
dim id
id=request.querystring("id")
sql="select * from dongtai where id ='"&id&"'"
rs.open sql,conn,3,3
错误
Microsoft JET Database Engine 错误 '80040e07'
Data type mismatch in criteria expression
