Thanks Steven,
But all I can see on this talk (on slide 89?) is the new syntax of
fetchall_arrayref, which is already used in my example.
I was looking for a better way to construct a while loop with
fetchall_arrayref. The problem is that when you fetch the last lot of data,
the statement handle becomes inactive, but you still have an reference to
your last set of data. Contrast this with a fetchrow_arrayref loop, which
has no data to return on the last fetch, so the reference is undef and the
loop exits cleanly, ie
while ( my $array_ref=$sth->fetchrow_arrayref()) {
# ... do something
}
works, but
while ( my $array_ref=$sth->fetchall_arrayref(undef, $maxfetch)) {
# ... do something in a loop
}
doesn't

See example from Tim's advanced DBI talk, last item.
