Question

Having some troubles with ON DUPLICATE KEY UPDATE in MySQL. Below is the query im trying to run.

INSERT INTO `Overall` ( `rsn` , `starting_xp` , `starting_lvl` ) VALUES ( 'iWader' , '195843626' , '2281' ) ON DUPLICATE KEY UPDATE `current_xp` = '195843626' AND `current_lvl` = '2281'

• It inserts fine, but when there is a duplicate it doesnt update, and doesnt throw any errors.
• Running the query through PMA returns no error and doesnt update
• Removing the ON DUPLICATE KEY UPDATE section returns a duplicate key error

This is the structure of my table

CREATE TABLE IF NOT EXISTS `overall` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `rsn` varchar(12) NOT NULL,
  `starting_xp` int(10) unsigned NOT NULL,
  `starting_lvl` int(10) unsigned NOT NULL,
  `current_xp` int(10) unsigned NOT NULL,
  `current_lvl` int(10) unsigned NOT NULL,
  PRIMARY KEY (`id`),
  UNIQUE KEY `rsn` (`rsn`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=1;

After ON DUPLICATE KEY UPDATE you should not need to use and with the fields, use , instead.

ON DUPLICATE KEY UPDATE `current_xp` = '195843626', `current_lvl` = '2281'
