<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

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
