Unable to Edit the View

I have changed the views table into camel case as, if the table is viewsview, i have changes it to ViewsView and the same with the column names. It is working fine, agter editing the queries in views.inc. It is able to show all the list of views what i have created. But once i edited the view and tru=ying to save it, it s=is displaying as "This view has a broken default display and cannot be used." and Error: Display refers to a plugin named '', but that plugin doesn't exist!. Not able to Insert or Edit the views.

Can anyone help me out in solving this issue.

Thanks in Advance.
