Asp.net连接SQL Server2000数据库例程详解:
   <%@ Import Namespace="System.Data" %>
   <%@ Import NameSpace="System.Data.SqlClient" %>
   <script laguage="VB" runat="server">
   sub page_load(sender as Object,e as EventArgs)
   Dim myConnection As SqlConnection
   Dim myCommand As SqlCommand
   Dim ds as DataSet
   '1.connect to sql server
   myConnection = New SqlConnection( "server=localhost;database=Pubs;uid=ueytjdf;pwd=doekdf" )
   myConnection.Open()
   la1.text="Connection Opened!"

   '2.Create a table
   myCommand = New SqlCommand( "CREATE TABLE [test] ([id] [int] IDENTITY (1, 1) NOT NULL ,[name]

   [char] (10) COLLATE Chinese_PRC_CI_AS NULL ,[sex] [char] (10) COLLATE Chinese_PRC_CI_AS NULL

   )", myConnection )
   myCommand.ExecuteNonQuery()
   la2.text="New table created!"

   '2 添加纪录
   myCommand = New SqlCommand( "Insert into [test] (name,sex) values( '黄志文','男' )",

   myConnection )
   myCommand.ExecuteNonQuery()
   la3.text="New Record Inserted!"

   '3 更新数据
   myCommand = New SqlCommand( "UPDATE [test] SET name='Smith' where name='李明'", myConnection )
   myCommand.ExecuteNonQuery()
   la4.text="Record Updated!"

   '4 删除数据
   myCommand = New SqlCommand( "delete from [test] where name='Smith'", myConnection )
   myCommand.ExecuteNonQuery()
   la5.text="Record Deleted!"

   '5 用DataGrid显示数据
   myCommand = New SqlCommand( "select * from [test]", myConnection )
   MyDataGrid.DataSource=myCommand.ExecuteReader()
   MyDataGrid.DataBind()
   end sub
   </script>
