NAME

Teng::Plugin::QueryBuilder - Query builder

SYNOPSIS

package MyApp::DB;
use parent qw/Teng/;
__PACKAGE__->load_plugin('QueryBuilder');

package main;
my $teng = MyApp::DB->new(dbh => ...);

# Basic usage
my $query = $teng->query;
$query->add_select('user.id' => 'user_id');
$query->from(['user']);
$query->add_where('user.name' => 'hiroaki');
$query->add_where('user.age' => {'>' => 20 });
$query->add_where('user.comment' => \'IS NULL');
my $iterator = $query->retrieve;

# Inner join technique
$joinner = $teng->query;
$joinner->from([]);
$joinner->add_join( user => [{
  type      => 'inner',
  table     => 'bookmark',
  condition => 'user.id = bookmark.user_id',
  }]);
$itrator = $joinner->retrieve;

DESCRIPTION

This is a Teng plugin, it provides query that was ported from resultset of DBIx::Skinny.

Teng was replacement of DBIx::Skinny, and it has compatibility of basic architecture. Therefore, Almost all source codes have been prepared by it. I only changed its namespace, and a name of the method to query from resultset.

However, the iterator which will be returned by the method retrieve, its function has degraded than Skinny's one (I think so). So you may have to dig its low-level data structure up to satisfy lack.
