<%@ 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()
