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 6,4651365131 answered Nov 2 '10 at 18:50 Ike Walker 33.4k95278 add a comment| up vote 18 down vote For those who are gettin

(errno: 150). If I understand correctly it is a foreign key problem, but I do not have a clue how to fix it. Would somebody be so kind and tell me how to get it working. error on rename The code used for creating table: CREATE TABLE categories( cid INT AUTO_INCREMENT NOT NULL PRIMARY KEY, assets_id INT NOT NULL, cat_name VARCHAR(30) NOT NULL, INDEX(assets_id), FOREIGN KEY (assets_id) REFERENCES asset(aid) ON UPDATE CASCADE ) ENGINE=INNODB DEFAULT CHARSET=utf8; The alter command: ALTER TABLE categories DROP COLUMN assets_id; The table categories is completely blank. So there is no information to set off the CASCADE restrictions. So could you help me what kind of wizardry do I need to delete the column assets_id. Thank you. mysql share|improve this question edited May 10 '11 at 10:50 Manoj 3,42564364 asked May 10 '11 at 10:31 Henkka 3623817 add a comment| 3 Answers 3 active oldest votes up vote 66 down vote accepted Use SHOW CREATE TABLE categories to show the name of constraint. Most probably it will be categories_ibfk_1 Use the name to drop the foreign key first and the column then: ALTER TABLE categories DROP FOREIGN KEY categories_ibfk_1; ALTER TABLE categories DROP COLUMN assets_id; share|improve this answer answered May 10 '11 at 10:37 Quassnoi 261k50430482 Thank you!

Hugo. RSS Feed. Baron Schwartz's Blog MySQL's ERROR 1025 explained Tue, Aug 22, 2006 in Databases MySQL issues a cryptic error message, “Error on rename,” when you try to alter a table in such a way that it would break a foreign key constraint: create table test1(a int not null primary key)engine=innodb; create table test2(a int not null, foreign key(a) references test1 (a)) engine=innodb; alter table test2 modify a smallint not null; ERROR 1025 (HY000): Error on rename of './test/#sql-2fa8_1' to './test/test2' (errno: 150) This happens because ALTER TABLE really works by making a copy of the table, then renaming to move the old table out of the way and move the new table into its place. It is certainly one of the less meaningful error messages I’ve seen in MySQL. There’s slightly more information in the output of SHOW ENGINE INNODB STATUS, if you are looking there (of course, if you’re looking there you’re probably already clued in to what’s going on). And innotop can parse that information for you: In case you didn’t understand why the foreign key constraint was failing, the error message innotop parses out is much clearer. It’s because the foreign key columns in the parent and child table have to have the same data type. I was trying to change the child’s column to an incompatible type.
