而且修改是使用update命令
大致如下步骤
xxx.asp
<%
ac = request("ac")'获取表单提交动作
if ac = "upd" then '是提交表单命令，进行修改数据库 *** 作
a=request("a")
exec = "update [tb1] set a=" &a
conn.execute(exec)'修改
response.write("<script>alert('修改成功！')location.href='xxx.asp'</script>")'修改成功d窗，跳回原界面
end if
%>
<form action="?ac=upd" method="post">
<input type="text" name="a" />
<input type="submit" name="sub" value="submit" />
</form>
《ASP编程大全》在此谁敢不从！1.提取字段列表
//<%
Set cn=Server.CreateObject("ADODB.Connection")
cn.Open "Provider=SQLOLEDBData Source=localhost" &_
"Initial Catalog=pubsUser ID=saPassword="
Set rs=cn.Execute("Select * from authors")
While Not rs.EOF
Response.Write rs("au_fname")
rs.MoveNext
Wend
rs.Close
cn.Close
//%>
2.返回数据集函数
Public Function GetData() As ADODB.Recordset
Dim cn As ADODB.Connection
Dim rs As ADODB.Recordset
Set cn=CreateObject("ADODB.Connection")
cn.Open "Provider=SQLOLEDBData Source=localhost" &_
"Initial Catalog=pubsUser ID=saPassword="
Set rs=CreateObject("ADODB.Connection")
rs.LockType=adLockBatchOptimistic
rs.CursorLocation=adUseClient
rs.CursorType=adOpenStatic
rs.Open "Select * from authors",cn
Set rs.ActiveConnection=Nothing
cn.Close
Set cn=Nothing
Set GetData=rs
End Function
3.从XML文件中读取数据
<!-- Metadata type="typelib" file="c:\program files\common files\system\ado\msado15.dll"-->
<%
'response.write admoderead &" " &adopenstreamfromurl
'response.End()
set rs = server.CreateObject("adodb.recordset")
Set stmData = Server.CreateObject("ADODB.Stream")
stmData.Charset="gb2312"'这一句很重要，否则会报一个错误。Recordset cannot be created from the specified source. The source file or stream must contain Recordset data in XML or ADTG format.移山祝大家好运^_^
xmbm = request.QueryString("xmbm")
if xmbm = "" then xmbm = "110100001"
Dim result
dim xml, XMLlength
Set DCOMServer = CreateObject("RemObjects.SDK.COMServer")
DCOMServer.MessageType = "TROBINMessage"
DCOMServer.ChannelType = "TROWinInetHTTPChannel"
DCOMServer.SetChannelProperty "TargetURL", "http://192.168.1.119:8089/BIN"
Set DCOMService = DCOMServer.CreateService("DCOMService")
xml = cstr("<?xml version="&chr(34)&"1.0"&chr(34)&" encoding="&chr(34)&"gb2312"&chr(34)&" ?>" &chr(13)&chr(10))
xml = xml &cstr(DCOMService.GetItem(xmbm))'用于生成XML主体的DCOM服务，实际中请灵活运用。
Set MegaDemoService = nothing
'response.write xml
'response.End()
stmData.Open
stmData.WriteText xml
stmData.SetEOS
'stmData.SaveToFile server.MapPath("zzzz"&session.SessionID&".xml"),2
'response.End()
stmData.Position = 0
rs.open stmData
if not rs.eof then
response.write "<table border = 1 cellpadding=5 cellspacing=0 bordercolor=black style='border-collapse:collapse'><tr bgcolor='#ddddeee'>"
for each fld in rs.fields
response.write "<td>" &fld.name &"</td>"
next
response.write "</tr>"
do while not rs.eof
response.write "<tr>"
for each fld in rs.fields
response.write "<td>" &fld.value &"</td>"
next
response.write "</tr>"
rs.movenext
loop
end if
rs.close

4.把数据写入XML文件

xmldoc.async = fasle
End Sub

set xmldoc = Nothing
End Sub
Public Property Let filePath(str)
xmlfile = str
End Property
Sub getRs(rs)
dim xmlhead
dim pNode,sNode
dim aNode,tNode
dim tableName
dim rf
dim i
set xmlhead = xmldoc.createProcessingInstruction("xml","version=""1.0"" encoding=""GB2312""")
xmldoc.insertBefore xmlhead,xmldoc.childNodes(0)
tableName = split(rs.Source,chr(32))
set pNode = xmldoc.CreateElement(tableName(3))
xmldoc.appendChild pNode
redim aNode(rs.Fields.Count-1)
do while not rs.eof
set sNode = xmldoc.CreateElement(tableName(3)&"list")
pNode.appendChild sNode
for i=0 to rs.Fields.Count-1
if rs.Fields(i).Name=tableName(3) then
tNode = rs.Fields(i).Name&"Child"
else
tNode = rs.Fields(i).Name
end if
set aNode(i) = xmldoc.CreateElement(tNode)
sNode.appendChild aNode(i)
if rs.Fields(i).value<>"" then
aNode(i).text = rs.Fields(i).value
end if
next
rs.movenext
loop
End Sub
Function saveFile()
on error resume next
xmldoc.save xmlfile
saveFile = (err.number=0)
End Function
End Class
%>
调用，把调用recordset就可以了。

rs.Open sql,conn,3,2
dim ixml
dim xf
set ixml = new autoXML
xf = "test.xml"
ixml.filePath = Server.MapPath(xf)
ixml.getRs(rs)
if ixml.saveFile() then
response.write "<a href=""" &Server.URLEncode(xf) &""">保存完毕</a>"
else
response.write "保存文件错误"
end if
set ixml = Nothing
rs.close

5.遍历XML文档
<%@ Language=VBScript %>
<% Option Explicit %>
<table border="1"><tr><th>Name</th><th>Number of Songs</th></tr>
<%
Dim objParser,objRoot,objNode,i
Set objParser=Server.CreateObject("MSXML.DOMDocument")

Response.Write "<tr><td>"
Response.Write objNode.getAttribute("name") &"</td><td align='center'>"
Response.Write objNode.childNodes.length
End if
Next
%>
</td></tr>
</table>
6.搜索XML元素
<%@ Language=VBScript %>
<% Option Explicit %>
//<%
Dim objDocument,objRoot,objNode,objNodeList
Set objDocument=Server.CreateObject("MSXML.DOMDocument")
objDocument.Load(Server.MapPath(%%1)) //"albums.xml"

If objNodeList.length=0 Then
Response.Write "No matches"
Else
Response.Write "<table border='1'><tr><th>Album</th><th>Year</th></tr>"
For each objNode in objNodeList

Next
Response.Write "</table>"
End If
End If
//%>
7.下载文件

//<%
call downloadFile(replace(Request("file"),"",""))

//%>
8.调用存储过程查询
<%@ Language=VBScript %>
<% Option Explicit %>
//<%
dim db,conn,myconn
db="/database/product.mdb"
Set conn = Server.CreateObject("ADODB.Connection")

response.end
end if
response.write"搜索到的记录如下:<br><br>"
do until rs.eof
response.write""&rs("id")&":"&rs("title")&"" '打印出文章的ID和标题
response.write"<br><br>"
rs.movenext
loop
'打扫战场
rs.close
conn.close
set rs=nothing
set conn = nothing
//%>
9.参数存储过程查询
'存储过程：
'在SQL中建立dbo.tse存储过程
CREATE PROCEDURE [dbo].[tse]
@keyword varchar(20)=null, '定义查询的关键字
@choose int=null'定义查询的类型（1为查询列title,其他为content）
as
if @choose=1
select * from web where title like @keyword + '%'
else
select * from web where content like @keyword + '%'
return
GO
'list.asp页
<%@ Language=VBScript %>
<% Option Explicit %>
//<%
dim db,conn,myconn
db="/database/product.mdb"

dim rs
dim sql
dim keyword
dim choose
keyword=request("keyword") '接收页面传送的值

set rs=server.createobject("adodb.recordset")
sql="exec tse '"&keyword&"',"&choose&"" '用exec执行tse存储过程，把keyword，choose给存储过程传递参数
rs.open sql,conn,1,1
if rs.eof and rs.bof then

end if
response.write"搜索到的记录如下:<br><br>"
do until rs.eof
