MySQL #1452 - 无法添加或更新子行：外键约束失败 ON DELETE CASCADE ON UPDATE CASCADE)

Question

I have 2 tables about music: songs and images, songs stores the song id, name, year, artist, audio. Artist is an indexed field it is in the images to identify the artist image. The problem happens when i want to insert a song in songs. appears this error:

INSERT INTO `songs` (`id`, `name`, `artist`, `year`, `audio`) VALUES ('0', 'x', 'x', '1000', 'x.mp3')

#1452 - Cannot add or update a child row: a foreign key constraint fails (`audio_player`.`songs`, CONSTRAINT `songs_ibfk_1` FOREIGN KEY (`artist`) REFERENCES `images` (`artist`) ON DELETE CASCADE ON UPDATE CASCADE)

both tables are empty.

any idea?

Answer 1

Well, i came too late, but: the error it's because i had to insert into images before of data of artist table
