ASP数据库中添加数据

我做了一个添加电脑的ASP页面,一个是index.asp,一个是tianjia_conn.asp,现在已经连接数据库,也可以向数据库中添加数据,但是关键是现在可以添加重复的数据,一条命令可以添加几十次上百次,我本来想法是添加数据之前查询一下数据库中是否有这条数据,如果有就跳出窗口说“数据已经存在”,如果没有这条数据则添加,请问怎么实现,下面是代码index.asp
<form name="form1" method="post" action="tianjia.asp" onsubmit="return checkform();">
<table width="100%" border="0" cellspacing="0" cellpadding="0">
<tr align="center">
<td width="35%" align="right">IP:</td>
<td width="16%" align="left"><input name="IP" type="text" id="IP"></td>

就是在插入钱先查询一遍,如果有就提示重复。
dim sql,rs
set rs=server.createobject("adodb.recordset")
sql="select * from us where MAC='"&MAC&"'" '这里我用MAC来判断是否存在,当然你可以改成其它的
rs.open sql,conn,1,3
if not rs.eof then
response.write "该MAC地址在数据库中已经存在"
response.end
end if
dim sql,rs
set rs=server.createobject("adodb.recordset")
sql="select * from us where MAC='"&MAC&"'" '这里我用MAC来判断是否存在,当然你可以改成其它的
rs.open sql,conn,1,3
if not rs.eof then
response.write "该MAC地址在数据库中已经存在"
response.end
end if

你添加数据 又不需要返回值!你写得麻烦了 可以用<%
set rs=conn.execute("Select count(*) as num form us where ip="&ip)
If rs.eof then
conn.execute("Insert into us ('字段','字段') values (后面是值)")
else
Response.write "false"
end if
%>
set rs=conn.execute("Select count(*) as num form us where ip="&ip)
If rs.eof then
conn.execute("Insert into us ('字段','字段') values (后面是值)")
else
Response.write "false"
end if
%>
