This has just caught me out in a while loop for getting information from a database

my $query = $dbh->prepare("SELECT idFrame, name, colour FROM F +rame"); $query->execute(); while (my ($frame) = $query->fetchrow_hashref) { push @frames, $frame; }

This loop never ends!
Although $query->fetchrow_hashref returns undef once all the rows have been returned, the condition as whole doesn't so the loop continues...

This is what I really wanted (and how have)

my $query = $dbh->prepare("SELECT idFrame, name, colour FROM F +rame"); $query->execute(); while (my $frame = $query->fetchrow_hashref) { push @frames, $frame; }
