    my $options = $dbi->options;

This method returns options that will be used for generating the connection DSN

Default: all passed options to constructor merged with system defaults:

    RaiseError  => 0,
    PrintError  => 0,
    PrintWarn   => 0,

=head2 password

    my $password = $dbi->password;

This is the L<Mojo::URL/password> that will be used for generating the connection DSN

default: none

=head2 ping

    $dbi->ping ? 'OK' : 'Database session is expired';

Checks the connection to database

=head2 port
