How to overwrite a table [only data]?

Hi list,<br /><br /> I would like to overwrite a table with problem with his original. But there are some points.<br
/><br/> I can't just delete and restore it becouse it has a foreign key and when I try to delete it ask for drop
cascade.<br/><br /> As I know the drop cascade delete in both tables the rows related. Is it correct ?<br /><br /><br
/>Regards...<br clear="all" /><br />-- <br />
