=head1 NAME

DBIx::Custom::Basic - DBIx::Custom basic implementation

=head1 See DBIx::Custom documentation

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

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

Please see L<DBIx::Custom> documentation

=head1 Filters

=head2 encode_utf8

    # Encode to UTF-8 byte stream (utf8::upgrade is done if need)
    $dbi->filters->{encode_utf8}->($value);
    
This filter is generally used as bind filter

    $dbi->bind_filter($dbi->filters->{encode_utf8});

=head2 decode_utf8

    # Decode to perl internal string
    $dbi->filters->{decode_utf8}->($value);
    
This filter is generally used as fetch filter

    $dbi->fetch_filter($dbi->filters->{decode_utf8});

=head2 Formats
    
strptime formats is available
    
    # format name        format
    'SQL99_date'         '%Y-%m-%d',
    'SQL99_datetime'     '%Y-%m-%d %H:%M:%S',
    'SQL99_time'         '%H:%M:%S',
    'ISO-8601_date'      '%Y-%m-%d',
    'ISO-8601_datetime'  '%Y-%m-%dT%H:%M:%S',
    'ISO-8601_time'      '%H:%M:%S',

You get format as the following

    my $format = $dbi->formats->{$format_name};

=head1 Methods

=head2 utf8_filter_on

    # Encode and decode utf8 filter on
    $dbi->utf8_filter_on;

This equel to

    $dbi->bind_filter($dbi->filters->{encode_utf8});
    $dbi->fetch_filter($dbi->filters->{decode_utf8});
