=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;
    
    # 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 C<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 C<connect (overridden)>

Connect to database.

    $dbi->connect;

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

=head2 C<connect_memory>

Connect memory database.

    $dbi->connect_memory;

=head2 C<last_insert_rowid>

Last insert row ID.

    $last_insert_rowid = $dbi->last_insert_rowid;
    
This is equal to SQLite last_insert_rowid() function.
