将ado方便的转化为xml文件_asp技巧

<!– #include file="adovbs.inc" –>

删除已经存在的文件
Dim objFSO
Set objFSO = Server.CreateObject("Scripting.FileSystemObject")
If objFSO.FileExists(Server.MapPath("db_xml.xml")) Then
    objFSO.DeleteFile Server.MapPath("db_xml.xml")
End IF
Set objFSO = Nothing

定义变量，很好的习惯
Dim cnnXML   ADO 连接
Dim rstXML   ADO 记录集

Set cnnXML = Server.CreateObject("ADODB.Connection")

cnnXML.Open "Provider=SQLOLEDB;Data Source=10.2.1.214;" _
    & "Initial Catalog=samples;User Id=samples;Password=password;" _
    & "Connect Timeout=15;Network Library=dbmssocn;"

Set rstXML = Server.CreateObject("ADODB.Recordset")
Set rstXML = cnnXML.Execute("SELECT * FROM scratch ORDER BY id;")

Response.Write "<p>Saving data as XML…</p>" & vbCrLf

保存xml各式的文件.
rstXML.Save Server.MapPath("db_xml.xml"), adPersistXML

关闭数据库连接，释放对象
rstXML.Close
Set rstXML = Nothing
cnnXML.Close
Set cnnXML = Nothing

Response.Write "<p>XML file written…</p>" & vbCrLf
Response.Write "<p>Click <a href=""db_xml.xml"">here</a> to view the file.</p>" & vbCrLf
