=head2 errstr

    my $errstr = $dbi->errstr;

This method just returns C<$DBI::errstr> value

=head2 error

    my $error = $dbi->error;

Returns error string if occurred any errors while working with database

    $dbi = $dbi->error( "error text" );

Sets new error message and returns object

=head2 host

    my $host = $dbi->host;

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

Default: C<localhost>

=head2 options

    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

    my $port = $dbi->port;

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

Default: none

=head2 query

    my $res = $dbi->query('select * from test');
    my $res = $dbi->query('insert into test values (?, ?)', @values);

Execute a blocking statement and return a L<Acrux::DBI::Res> object with the results.
You can also append a 'bind_callback' to perform binding value manually:

    my $res = $dbi->query('insert into test values (?, ?)', {
        bind_callback => sub {
            my $sth = shift;
            $sth->bind_param( ... );
          }
      });

=head2 rollback

    $dbi->begin;
    # ...
    $dbi->rollback;

This is a transaction method!

This method discards all changes to the database and marks the end
point for the transaction to complete

See also L</begin>, L</commit>

=head2 transaction

    my $tx = $dbi->transaction;

Begin transaction and return L<Acrux::DBI::Tx> object, which will automatically
roll back the transaction unless L<Acrux::DBI::Tx/commit> has been called before
it is destroyed

    # Insert rows in a transaction
    eval {
      my $tx = $dbi->transaction;
      $dbi->query( ... );
      $dbi->query( ... );
      $tx->commit;
    };
    say $@ if $@;

=head2 url

    my $url = $dbi->url;
    $dbi = $dbi->url('sqlite:///tmp/test.db?sqlite_unicode=1');
    $dbi = $dbi->url('sqlite:///./test.db?sqlite_unicode=1'); # '/./' will be removed
    $dbi = $dbi->url('postgres://foo:pass@localhost/mydb?PrintError=1');
    $dbi = $dbi->url('mysql://foo:pass@localhost/test?mysql_enable_utf8=1');

Database connect url

The database connection URL from which all other attributes can be derived.
C<"url"> must be specified before the first call to C<"connect"> is made,
otherwise it will have no effect on setting the defaults.

For using SQLite databases with files relative to current directory you cat use '/./' prefix:

    # '/./' will be removed automatically
    $dbi = $dbi->url('sqlite:///./test.db?sqlite_unicode=1');
