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 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 KE

If so, you may need to remove the foreign relationships that you have defined for that column, then rename, then place your foreign key relationships back in place with the new column name. I think MySQL is getting hung up on the fact that when you rename, the FK relationships are no longer valid and it is throwing an error. EDIT: Confirmed FK Rename in MySQL You will need to do something like this: alter table yourTable drop foreign key yourID share|improve this answer edited May 27 '10 at 12:29 answered May 27 '10 at 12:23 Tommy 27.4k45392 That was it.

Hugo. RSS Feed. Baron Schwartz's Blog MySQL's ERROR 1025 explained Tue, Aug 22, 2006 in Databases MySQL issues a http://www.xaprb.com/blog/2006/08/22/mysqls-error-1025-explained/ 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: http://www.shahalpk.name/post/63368393191/mysql-error-1025-on-rename-of-blahblah-errno 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 error 1025 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 error on rename 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.

above error popped up. My SQL command was ALTER TABLE `admin_user` DROP `store_id`; and the error… MySQL Error #1025 Error on rename of '.\magento\#sql-1378_1b9' to '.\magento\admin_user' (errno: 150) I’ve learned this error is associated with some foreign key related stuff. My column store_id was a foreign key referencing another table core_store. Although the error wasn’t much informative, googling the error code will link you to pretty good results. In my case, all i have to do was to drop the associated foreign key and then drop the column. To find the foreign key name you can execute the following query select constraint_name from information_schema.key_column_usage where table_name like 'admin_user' and column_name like 'store_id'; +------------------------------------------------------------+ | constraint_name | +------------------------------------------------------------+ | FK_ADMIN_USER_WEBSITE_ID_REF_CORE_STORE_WEBSITE_ID | +------------------------------------------------------------+ Now drop the foreign key… alter table admin_user drop foreign key FK_ADMIN_USER_WEBSITE_ID_REF_CORE_STORE_WEBSITE_ID And finally drop the column… alter table `admin_user` drop `store_id`; 0 Kudos 0 Kudos Show Notes jonathanmiami liked thisjonathanmiami reblogged this from shahalpkshahalpk posted this Read this next: More shahalpk. do. overdo. @shahalpk sayhello © 2011–2016
