You could probably, with a bit of work, use a hash and a list of values. Here's some relatively untested, unbeautiful stuff that makes me more likely to stick with declaring the variables in advance:
my %columns;
# stuff here
$sth->bind_columns(
map { \${ $columns{$_} } @{ $sth->{NAME_lc} }
) || die("unable to bind columns: ", $sth->errstr);
# dereference somehow, may not be correct
while($sth->fetch) {
print "<tr><td>$name</td><td>$columns{price}</td></tr>\n";
print "<tr><td colspan=\"2\">$columns{description}</td></tr>\n";
}
Update: Yeah, there's really no big benefit to doing it this way. :)
