As the title suggests, i'm trying to add more elements to my existing ENUM-type column. I'm using MySQL Workbench 6.3 for my database.
CREATE TABLE `quantum` (
`id` bigint(20) NOT NULL AUTO_INCREMENT,
`type` enum('a','b','c','d','e') CHARACTER SET latin1 NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=MyISAM AUTO_INCREMENT=11173 DEFAULT CHARSET=utf8;
then I try to alter type column to add another element f
ALTER TABLE quantum
MODIFY COLUMN type enum('a','b','c','d','e','f') NOT NULL
then MySQL Workbench 6.3 is giving me some weird error
