This allows constructions like my $rows=$sth->execute or die "SQL error" ( Of course this would be expressed better using $dbh->{RaiseError} = 1).
The relevant part of the DBI documentation states:
For a non-`SELECT' statement, `execute' returns the number of rows
affected, if known. If no rows were affected, then `execute' returns
"`0E0'", which Perl will treat as 0 but will regard as true. Note that
it is not an error for no rows to be affected by a statement. If the
number of rows affected is not known, then `execute' returns -1.
