html head http-equiv=Content-Type content=text/html; charset=gb2312 title/title /head body % LANGUAGE = VBScript % % Const ForReading = 1, ForWriting = 2, ForAppending = 8 Const TristateUseDefault = -2, TristateTrue = -1, TristateFalse

< %
set rs=server.CreateObject("adodb.recordset")
db="db.mdb"

set conn=server.CreateObject("adodb.connection")
connstr="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & Server.MapPath(db)
conn.open connstr

Set rs=Conn.OpenSchema(20)
Do Until rs.EOF

If rs(3)="TABLE" Then
response.write "表名:"&rs(2)&"<br />"
Set rs1=server.CreateObject("adodb.recordset")
sql="select * from "&rs(2)
Set rs1=conn.execute(sql)
response.write "字段名:"
For i=0 To rs1.fields.count-1
response.write rs1.fields(i).name&" "
Next
response.write "<br />"

Do While Not rs1.eof
response.write " "
For i=0 To rs1.fields.count-1
t=rs1.fields(i).name
response.write rs1(t)&" "
Next
response.write " "
rs1.movenext
Loop
response.write " "
End If
