看来楼主真的该先学学asp了 基础啊。。。
这个只需要在我3楼的基础上改一句就行:
If dbrs.eof Then
dbrs.addnew
dbrs("学号")=rs("学号")
dbrs("姓名")=rs("姓名")
dbrs("导入时间")=Date
dbrs.update
dbrs.close
Else
response.write rs("学号") & " " & rs("姓名") & "已存在<br />"
End If

set conn2 =server.createobject("adodb.connection")
conn2.open "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" &EexcelDB& ";Extended Properties=Excel 8.0"
sql = "select * from [sheet1$]"
set rs = conn2.execute(sql)
strsql = "select * from userinfo"
while not rs.eof
set rs1 = server.createobject("adodb.recordset")
rs1.open strsql,conn,1,3
rs1.addnew  
rs1("username") = fixsql(rs(0))

response.write "<script language='javascript'>" & chr(13)
