in sql:

"SELECT COUNT(*) FROM people"

doing the same in perl would be horribly inefficient, unless you're going to do something else with the results afterwards. here's a minimal version anyway, in case for some reason select count isn't possible:

my $records = $dbh->selectcol_arrayref('SELECT location FROM people');
my $peoplecount = scalar(@$records);

update: curses... redundant again.
