# DBIx::Class::Manual::ResultClass(3pm)

Representing a single result (row) from a DB query

## NAME

DBIx::Class::Manual::ResultClass - Representing a single result (row) from a DB query

## SYNOPSIS

```
  package My::Schema::Result::Track;
  use parent 'DBIx::Class::Core';
  __PACKAGE__->table('tracks');
  __PACKAGE__->add_columns({
    id => {
      data_type => 'int',
      is_auto_increment => 1,
    },
    cd_id => {
      data_type => 'int',
    },
    title => {
      data_type => 'varchar',
      size => 50,
    },
    rank => {
      data_type => 'int',
      is_nullable => 1,
    },
  });
  __PACKAGE__->set_primary_key('id');
  __PACKAGE__->add_unique_constraint(u_title => ['cd_id', 'title']);
```

## DESCRIPTION

In DBIx::Class, a user normally receives query results as instances of a certain `"Result Class"`, depending on the main query source.  Besides being the primary "toolset" for interaction with your data, a `"Result Class"` also serves to establish source metadata, which is then used during initialization of your DBIx::Class::Schema instance.

Because of these multiple seemingly conflicting purposes, it is hard to aggregate the documentation of various methods available on a typical `"Result Class"`. This document serves as a general overview of `"Result Class"` declaration best practices, and offers an index of the available methods (and the Components/Roles which provide them).
