asp.net 学习笔记[02] 便捷数据邦定

[align=center]便捷数据邦定[/align]

DataSource控件
将并行操作变为串行操作，并且连接方便。不需要i编写连接代码
该控件可以通过设置参数对数据进行操作
代码例子：


<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConflictDetection="CompareAllValues"


ConnectionString="<%$ ConnectionStrings:pubsConnectionString %>" DeleteCommand="DELETE FROM [authors] WHERE [au_id] = @original_au_id AND [au_lname] = @original_au_lname AND [au_fname] = @original_au_fname AND [phone] = @original_phone AND [address] = @original_address AND [city] = @original_city AND [state] = @original_state AND [zip] = @original_zip AND [contract] = @original_contract"


InsertCommand="INSERT INTO [authors] ([au_id], [au_lname], [au_fname], [phone], [address], [city], [state], [zip], [contract]) VALUES (@au_id, @au_lname, @au_fname, @phone, @address, @city, @state, @zip, @contract)"


SelectCommand="SELECT * FROM [authors]" UpdateCommand="UPDATE [authors] SET [au_lname] = @au_lname, [au_fname] = @au_fname, [phone] = @phone, [address] = @address, [city] = @city, [state] = @state, [zip] = @zip, [contract] = @contract WHERE [au_id] = @original_au_id AND [au_lname] = @original_au_lname AND [au_fname] = @original_au_fname AND [phone] = @original_phone AND [address] = @original_address AND [city] = @original_city AND [state] = @original_state AND [zip] = @original_zip AND [contract] = @original_contract">
