[求助]一段程序——数据库上传问题

我用了豆腐的附件上传到数据库的技术,上传下载都已经成功完成了。
但当没有附件的时候表单的其他内容就没办法传到数据库里了,我知道要加一个限制语句,可是加哪句我实在不知道了,拜托帮我看看好不?

下面是我的添加界面:

Set objUpload = New doufuUpload
objUpload.MaxSize=10485860 '允许10M的附件上传
objUpload.upload
%>

<%
DBSaveUpload objUpload.file("File1")
%>
<script language=javascript>
alert("新问题添加成功!")
{
window.location.href = "add_wt.asp"
}
</script>
<%end if%>
<%
function OpenConn()
set conn=server.createobject("ADODB.Connection")
Conn.Open "Provider=OraOLEDB.Oracle.1;Persist Security Info=True;User ID=sjkgl;Password=sjkgl;Data Source=ljl"
set OpenConn=Conn
end function
sub DBSaveUpload(Fields)
set conn=openConn()
Set RS = Server.CreateObject("ADODB.Recordset")
RS.Open "select * from wtgl1", Conn, 2, 2
RS.AddNew
Rs("lb")=objUpload.form("lb").value
Rs("nrms")=objUpload.form("nrms").value
Rs("sspt")=objUpload.form("sspt").value
Rs("tcr")=objUpload.form("tcr").value
Rs("yxj")=objUpload.form("yxj").value
Rs("fl")=objUpload.form("fl").value

'If Filename<>"" Then '就是这里应该怎么写?
Rs("filename")=Fields.Filename
RS("ContentType")=Fields.ContentType
RS("fj").AppendChunk Fields.Blob
'end if
RS.Update
RS.Close
Conn.Close
end sub
%>


我祛除了里面的其他代码,这样方便查看````
