造成此错误的原因是：尝试转发工程师时出现错误1452

Question

尝试转发我的数据库并且我收到此错误：

ERROR: Error 1452: Cannot add or update a child row: a foreign key constraint fails (`cat10e`.`album`, CONSTRAINT `fk_album_artist` FOREIGN KEY (`art_id`) REFERENCES `artist` (`art_id`) ON DELETE NO ACTION ON UPDATE NO ACTION)

INSERT INTO `cat10e`.`album` (`album_id`, `art_id`, `label_id`, `album_name`, `album_cost`, `album_tracks`, `album_rating`, `album_producer`, `album_genre`, `album_note`) VALUES (1, 1, 1, 'legends of country', 55.55, 4, 4, 'poor jim', 'country', NULL)

Answer 1

问题是我没有将任何数据放入引用的表中。将插入添加到artist表中可以解决错误。
