Slightly [OT]...
my @names = $db->query('SELECT name FROM people WHERE id > 5')->flat;
I thought that looked nice so I had a look at it. But when
compared to the 'normal' DBI way it turns out there is really not much of an advantage. The line is a little shorter (++) but you get a dependency (--) and lose quite a bit of speed (--).
perl -MData::Dumper -MDBI -MDBIx::Simple -e '
my $db1 = DBI->connect; # (uses defaults to connect)
my $db2 = DBIx::Simple->connect;
use Benchmark qw( cmpthese ) ;
my $COUNT = -20;
print "-- COUNT [$COUNT]\n";
cmpthese( $COUNT, {
selectrow_arrayref => sub { my @arr = @{ $db1->selectrow_arrayref(
+ "select i from generate_series(1,10) as f(i) where i > 5" ) }; },
dbix_query_flat => sub { my @arr = $db2->query( "select i from
+generate_series(1,10) as f(i) where i > 5")->flat; },
});

Rate dbix_query_flat selectrow_arrayref

As always when I look closer at ORMy things (mainly because many people seem to be fond of ORMs), I don't think it's worth it. |
