If you don't need a full ORM (and it looks like that's not the point for you) you probably just want SQL::Translator instead:

#!perl

use strict;
use warnings;
use 5.010;

use SQL::Translator;
use Data::Dumper;
use SQL::Translator::Parser::SQLite;

my $data = do { local $/;
                open my $fh, '<', 'data.sql' or die "Can't read file: 
+$!\n";
                <$fh> };

my $sqlt = SQL::Translator->new;
SQL::Translator::Parser::SQLite::parse($sqlt, $data);

my $schema = $sqlt->schema;
print Dumper([ map { $_->name } $schema->get_table('s')->get_constrain
+ts ]);

Gives me:

$VAR1 = [
          'fkey'
        ];

See SQL::Translator::Schema::Constraint for any other methods to call on the Constraint object. It's a bit convoluted to use like this; normally you'd use SQL::Translator to, as the name implies, translate your DDL from a format (e.g. SQLite-style SQL) into another (e.g. MySQL).
