=head1 NAME

DBIx::Custom::SQLite - a SQLite implementation of DBIx::Custom

=head1 SYNOPSYS

    use DBIx::Custom::SQLite;

    # Connect

    my $dbi = DBIx::Custom::SQLite->connect(user      => 'taro', 

                                            password => 'kl&@K',

                                            database  => 'your_database');

    # Connect memory database

    my $dbi = DBIx::Custom::SQLite->connect_memory;

    # Reconnect memory database

    $dbi->reconnect_memory;

    # Last insert row ID

    my $id = $dbi->last_insert_rowid;

=head1 ATTRIBUTES

This class is L<DBIx::Custom> subclass.

You can use all attributes of L<DBIx::Custom>.

=head2 database

Database name

    $dbi      = $dbi->database('your_database');

    $database = $dbi->database;

=head1 METHODS

This class is L<DBIx::Custom> subclass.

You can use all methods of L<DBIx::Custom>.

=head2 connect - overridden

Connect to database.

    $dbi->connect;

If you set database, host, or port, data source is automatically created.

=head2 connect_memory

Connect memory database.

    $dbi->connect_memory;

=head2 reconnect_memory

Reconnect to memory databsse.

    $dbi->reconnect_memory;

=head2 last_insert_rowid

Last insert row ID.

    $last_insert_rowid = $dbi->last_insert_rowid;

This is equal to SQLite last_insert_rowid() function.
