Unless this is something you do only once in your program, you shouldn't reconnect to the database every time you need to do a select.
Instead, you should connect once and then use the database handle throughout your program; e.g., you would pass it to all subroutines that work with the DB. 
# example
my $dbh = DBI->connect( ... );

#...
my @row = doSelect($dbh, 'foobar');
#...

sub doSelect{
  my ($dbh, $table) = @_;
  my $sth = $dbh->prepare("SELECT * FROM $table LIMIT 1");
  $sth->execute();
  return $sth->fetchrow_array();
}

As VSarkiss already mentioned, it makes little sense to pass the statement handle ($sth) back from the subroutine.
Pass the result set instead. Of course, you need to make sure that your query won't return too many rows...
