Is that even allowed? Or is your case different, in which case http://stackoverflow.com/questions/160233/what-does-mysql-error-1025-hy000-error-on-rename-of-foo-errorno-150-me you should start another thread? –Rick James Jan 9 at 6:35 @RickJames Yes it is. However, skiphoppy should add her comment under the answer she elected, as the bouty message will disappear when the bounty is over. –RandomSeed Jan 11 at 15:25 add a comment| 10 Answers 10 active oldest votes up vote 181 down vote accepted You usually get this error if your tables use the InnoDB engine. In that case you would have to drop the foreign key, and then do the alter table and drop the column. But the tricky part is that you can't drop the foreign key using the column name, but instead you would have to find the name used to index it. To find that, issue the following select: SHOW CREATE TABLE region; This should show you the name of the index, something like this: CONSTRAINT region_ibfk_1 FOREIGN KEY (country_id) REFERENCES country (id) ON DELETE NO ACTION ON UPDATE NO ACTION Now simply issue an: alter table region drop foreign key region_ibfk_1; And finally an: alter table region drop column country_id; And you are good to go! share|improve this answer answered Apr 11 '11 at 0:45 Jeshurun 13.3k45069 7 If I could upvote this twice I would.
