I would recommend not to change RaiseError back to 0. It just make things easier.
That depends.

For one-off scripts it certainly makes things easier, however when you write larger applications you almost certainly want to raise your own exceptions so you can then catch them by type (using Exception::Class or something similar - "Perl best practices" has a chapter on it) and then you are better off doing something like 

$sth->execute or MyApp::DBException( error => $sth->errstr )->throw;

rather than using RaiseError.
