You can drop the foreign keys and then the table.  Then when you recreate
and repopulate the table, you can add the foreign keys back at the very end.

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 ?</blockquote><div><br>You can drop the foreign keys and then the table.&nbsp; Then when you recreate and repopulate the table, you can add the foreign keys back at the very end.
