ASP Microsoft JET Database Engine 错误 '80040e10' 至少一个参数没有被指定值。

<%set db = server.CreateObject("adodb.Connection")db.open"Provider=Microsoft.Jet.OLEDB.4.0;Data source="+Server.MapPath("tiger.mdb")+";"%><%dim strsql,rsdim ip1,riqi1,shijian1ip1=Request.ServerVariables("REMOTE_ADDR")riqi1=date()shijian1=time()response.write(ip1)response.write(" ")response.write(riqi1)response.write(" ")response.write(shijian1)strsql="insert into tigerdata(ip,riqi,shijian) values (ip1,riqi1,shijian1)"db.execute(strsql)%>

<%set db = server.CreateObject("adodb.Connection")db.open"Provider=Microsoft.Jet.OLEDB.4.0;Data source="+Server.MapPath("tiger.mdb")+";"%><%dim strsql,rsdim ip1,riqi1,shijian1ip1=Request.ServerVariables("REMOTE_ADDR")riqi1=date()shijian1=time()response.write(ip1)response.write(" ")response.write(riqi1)response.write(" ")response.write(shijian1)strsql="insert into tigerdata(ip,riqi,shijian) values (ip1,riqi1,shijian1)"db.execute(strsql)%>

这是你的代码原来的样子，
问题应该是出在执行语句：
insert into tigerdata(ip,riqi,shijian) values (ip1,riqi1,shijian1)
这里没有指定对应字段的值或者数据类型不正确。
建议修改为：
strsql="insert into tigerdata(ip,riqi,shijian) values ('"& ip1 & "',#"&riqi1&"#,#"&shijian1&"#)"

book之没有被传过去，变成了book=request.cookies("bookid")set rs=server.createobject("adodb.recordset") books="select * from data where bookid ="rs.open books,conn,1,3 所以出现了错误.检查book变量是否有值
