$sth->finish should be inserted if (and ONLY if) the C<...fetch some data>
does NOT fetch ALL data in the select. If you do some thing like:
while (my $r=$sth->fetchrow_arrayref) {
.. handle data;
}
there is no reason to call finish, but if you do
while (...$sth->fetch..) {
....
last if <some condition>;
}
you will have to call finish, but I would reccomend using
another name for the second statement (that would help
the poor sod who will try to understand this in a years time :)
