注意：要运行上述ACCESS例程请先有Access数据库, 与例程放在同一目录下。
<%@ Import Namespace="System.Data" %>
<%@ Import NameSpace="System.Data.OleDb" %>
<script laguage="VB" runat="server">
Dim myConnection As OleDbConnection
Dim myCommand As OleDbCommand
sub page_load(sender as Object,e as EventArgs)

'1.连接数据库
dim dbname as string
dbname=server.mappath("authors.mdb")
myConnection = New OleDbConnection( "PROVIDER=Microsoft.Jet.OLEDB.4.0;DATA Source="&dbname )
myConnection.Open()
la1.text="Connection Opened!"

'2.添加记录
myCommand = New OleDbCommand( "Insert INTO Authors(Authors,country) Values('Simson','usa')", myConnection )
myCommand.ExecuteNonQuery()
la2.text="New Record Inserted!"

'3 更新数据(Access)
myCommand = New OleDbCommand( "UPDATE Authors SET Authors='Bennett' WHERE Authors = 'Simson'", myConnection )
myCommand.ExecuteNonQuery()
la3.text="Record Updated!"

'4 删除数据（access）
myCommand = New OleDbCommand( "DELETE FROM Authors WHERE Authors = 'David'", myConnection )
myCommand.ExecuteNonQuery()
la4.text="Record Deleted!"

'5 使用DateGrid显示数据
myCommand = New OleDbCommand( "select * FROM Authors", myConnection )
MyDataGrid.DataSource=myCommand.Executereader()
MyDataGrid.DataBind()

end sub
</script>

这是ASP连接Sqlserver程序，你可以直接copy下来，然后根据自己需要进行修改就可以了
<%
Dim mode
mode=request.form("text4")
if mode=1 then
name=request.form("text1")
age=request.form("text2")
addr=request.form("text3")
if not isnumeric(age) then response.write "age must be number!<a href=javascript:history.go(-1)>try again</a>":response.end
age=clng(age)
end if
