For this tried to create same table with create SQL but it says #1005 - Can't create table 'mydb.table1' (errno: 150) Now I created same schema table with table name table2, this was successfully created but as my application code is http://dba.stackexchange.com/questions/86853/1025-error-on-rename-of-table-errno-150-table-was-deleted-while-tried-to-a written for table1, I need to rename this table to table1 again on which gives me following error. #1025 - Error on rename of table errno: 150 Also tried to run alter table query with set foreign_key_checks = 0. But same error. While searching I came accross below SQL, SHOW INNODB ENGINE STATUS; Which displays following message 141223 11:30:10 Error in foreign key constraint of table myahd/table1: there is no index in the table which would contain the columns as the first columns, or the data types in the table do not match the ones in the referenced table or one of the ON ... SET NULL columns is declared NOT NULL. Constraint:, CONSTRAINT "fk_key9" FOREIGN KEY ("updated_by") REFERENCES "users" ("userid") ON DELETE NO ACTION ON UPDATE NO ACTION While there is no such table listed in my database with name table1. Nor any such key is found with fk_key9. May be I can delete this table1's idb or frm file, but unable to locate it. Or may be there is some other solution.

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 http://symfony-world.blogspot.com/2010/10/mysql-error-on-rename-when-dropping.html 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 error on 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.

Recently I wanted to remove a column from phpmyadmin that is covered with a constraint. Impossible to do so, MySQL throws following error: ERROR 1025 (HY000): Error on rename of './optiner_prestadmin/#sql-6bc_3e6' to './optiner_prestadmin/order_history' (errno: 150) You may get above error when executing a query removing index, e.g. ALTER TABLE order_history DROP INDEX user_id;Fortunately, there is a solution, not very easy to find in the internet (I used comments from this article). execute the following in MySQL: SHOW CREATE TABLE order_history;You shall get something like: order_history | CREATE TABLE `order_history` ( `order_id` bigint(20) NOT NULL, `user_id` bigint(20) NOT NULL, `status_id` bigint(20) NOT NULL, `informed` tinyint(1) DEFAULT '0', `comment` text, `created_at` datetime NOT NULL, `created_by` bigint(20) NOT NULL DEFAULT '1', PRIMARY KEY (`id`), KEY `order_id_idx` (`order_id`), KEY `user_id_idx` (`user_id`), KEY `status_id_idx` (`status_id`), KEY `created_by_idx` (`created_by`), CONSTRAINT `order_history_created_by_sf_guard_user_id` FOREIGN KEY (`created_by`) REFERENCES `sf_guard_user` (`id`) ON DELETE CASCADE, CONSTRAINT `order_history_order_id_order_info_id` FOREIGN KEY (`order_id`) REFERENCES `order_info` (`id`), CONSTRAINT `order_history_status_id_order_status_id` FOREIGN KEY (`status_id`) REFERENCES `order_status` (`id`), CONSTRAINT `order_history_user_id_sf_guard_user_id` FOREIGN KEY (`user_id`) REFERENCES `sf_guard_user` (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=28305 DEFAULT CHARSET=utf8 we want to delete the whole column user_id (with all corresponding indices, constraints, etc.) - need to drop the FOREIGN KEY first: ALTER TABLE order_history DROP FOREIGN KEY `order_history_user_id_sf_guard_user_id`;you'll find the name of the foreign key in the last constraint clause. finally, drop the column: ALTER TABLE `order_history` DROP `user_id`;and that's it!
