推荐答案

对于初学者来说，

For starters, this tutorial actually gives a pretty good demonstration on the creation and subsequent alteration of the data model.

My suggestion to see if everything is good would be to look at the code behind for the insert and update actions. Make sure that your new fields appear here as they should and that any sql or procedure calls have the parameters properly defined. If you are access procedures, make sure that the database itself has the new fields properly implemented.

If at this point you are still getting errors or struggling with this, post some relevant code snippets and we can examine the issue from that perspective.
