This is the query:
UPDATE `ruen_kw` SET case='nominative' WHERE id='42'
The table:
CREATE TABLE `ruen_kw` (
  `id` tinyint(6) NOT NULL auto_increment,
  `language` varchar(2) NOT NULL,
  `keyword` varchar(80) character set utf8 NOT NULL,
  `translation` varchar(300) NOT NULL,

  PRIMARY KEY  (`id`),
  FULLTEXT KEY `keyword_2` (`keyword`)
) ENGINE=MyISAM  DEFAULT CHARSET=latin1 AUTO_INCREMENT=46 ;
The line to be updated:
INSERT INTO ruen_kw (id, language, keyword, translation, case, tense, gender, number, definition) VALUES
(42, 'ru', 'хозÑйка', 'hostess', 'nom', '', '', '', '');
