NAME
       DBIx::Class::Schema::Loader::DBI::Writing - Loader subclass writing
       guide for DBI

SYNOPSIS
	 package DBIx::Class::Schema::Loader::DBI::Foo;

	 # THIS IS JUST A TEMPLATE TO GET YOU STARTED.

	 use strict;
	 use warnings;
	 use base 'DBIx::Class::Schema::Loader::DBI';
	 use mro 'c3';

	 sub _table_uniq_info {
	     my ($self, $table) = @_;

	     # ... get UNIQUE info for $table somehow
	     # and return a data structure that looks like this:

	     return [
		[ 'keyname' => [ 'colname' ] ],
		[ 'keyname2' => [ 'col1name', 'col2name' ] ],
		[ 'keyname3' => [ 'colname' ] ],
	     ];

	     # Where the "keyname"'s are just unique identifiers, such as the
	     # name of the unique constraint, or the names of the columns involved
	     # concatenated if you wish.
	 }

	 sub _table_comment {
	     my ( $self, $table ) = @_;
	     return 'Comment';
	 }

	 sub _column_comment {
	     my ( $self, $table, $column_number ) = @_;
	     return 'Col. comment';
	 }

	 1;

DETAILS
       The only required method for new subclasses is "_table_uniq_info", as
       there is not (yet) any standardized, DBD-agnostic way for obtaining
       this information from DBI.

       The base DBI Loader contains generic methods that *should* work for
       everything else in theory, although in practice some DBDs need to
       override one or more of the other methods.  The other methods one might
       likely want to override are: "_table_pk_info", "_table_fk_info",
       "_tables_list" and "_extra_column_info".	 See the included DBD drivers
       for examples of these.

       To import comments from the database you need to implement
       "_table_comment", "_column_comment"
