To find out which table caused the error you can run SHOW ENGINE INNODB STATUS and then look at the LATEST FOREIGN KEY ERROR section. share|improve this answer edited Nov 20 '14 at 11:00 trejder 6,4401365130 answered Nov 2 '10 at 18:50 Ike Walker 33.3k95277 add a comment| Did you find this question interesting?

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 13.1k4

The foreign key references another table's id. However, I don't need this field. I've tried removing the fk index, which doesn't work - says it's needed in a foreign key contraint. And removing the field, which gives me an error: 1025 - Error on rename of './axis/#sql-ad8_1531' to './axis/Schedule' (errno: 150) The table is currently error on rename empty. There are no tables referencing this field. Any ideas on how to get rid of this? Other than creating a new table? If I'm reading the below error correctly, I can't drop the column since the fk index is declared. And I can't drop the index, because the column exists. Chicken & Egg??

which outputs 1025 - Error on rename of './postuj_cz1/#sql-d834_a0c704'
to './postuj_cz1/comments' (errno: 150)
The id_user on the other table is simple primary key index. I'm using MySQL version 5.0.85 Anonymous Answer Email {} Share According to this link, the error relates to the definition of the primary key field. The error isn't about the foreign key index. Check the primary key for the COMMENTS table to make sure it does not have the UNSIGNED keyword while the COMMENTS.id_user foreign key had the UNSIGNED keyword. This keyword was causing the problem - inconsistent type of field. To fix, add the UNSIGNED keyword to the primary key definition for the COMMENTS table. Or remove the UNSIGNED keyword from the foreign key definition...
