如果这是一个Web项目，您没有这么说.无论哪种方式，答案都是您使用SQL进行所需的更改.如果它是一个Web项目，我将使用一个AJAX调用，并传递正确的ID，但是通过两种方式，您都可以处理选择更改事件或提交"按钮的事件，以运行SQL .

If this is a web project, you did not say so. Either way, the answer is that you use SQL to make the changes you want. If it''s a web project, I''d use an AJAX call, passing in the correct id, but both ways, you handle a selection changed event, or the event of a ''commit'' button, to run your SQL.
