Is that even allowed? Or is your case different, in which case 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 179 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 DELE

Laravel Drop Foreign Key
trying to drop a generic index to replace it with a unique index of the same http://stackoverflow.com/questions/160233/what-does-mysql-error-1025-hy000-error-on-rename-of-foo-errorno-150-me name, it popped up because there was a foreign key (FK) constraint on a field that was the first field of the index I wanted to drop, and if I dropped the index, http://noopsi.com/item/11684/ then there would be no index with the FK constraint as the first field. How I solved it: I created the new unique index with the same fields but a different name, I was then able to drop the old generic index supposedly running: mysql> SHOW ENGINE INNODB STATUS; will show you this error, but the output is archaic.

Any ideas? Foreign key stuff? Anonymous Answer Email error on rename {} Share 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!
