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 6,5031366131 answered Nov 2 '10 at 18:50 Ike Walker 33.6k95278 add a comment| up vote 18 down vote For those who are getting to this question via google... this error can also happen if you try to rename a field that is acting as a foreign key. share|improve this answer answered Jun 20 '13 at 13:03 Dave C 267521 add a comment| up vote 18 down vote As was said you need to remove the FKs before.

You will need to drop the foreign key, change the data type of both the parent and child columns, and then add the foreign key again. For details on this error, run SHOW ENGINE INNODB STATUS\G and then look at the LATEST FOREIGN KEY ERROR section. share|improve this answer answered Mar 17 '11 at 15:33 Ike Walker 33.6k95278 add a comment| up vote 0 down vote but it is very hard if you want to change in the whole charset to utf8 of all tables here is what i did 1 export the database (all tables) and open by notepad 2 replace all "latin1" by utf8 and save 3 then try to restore using mysqlAdministrator but it says wrong 4 so try restoring again but you have to select ignore errors radio button 5 it tries to restore some tables 6 then you have to restore again until no error message i know this is the hard way but i am sure th
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: https://bugs.mysql.com/bug.php?id=10333 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.

How to repeat: 1. Start the MySQL client and connect to the database. 2. Set the delimiter to //. 3. Run the following commands to create and use a database. drop database if exists db1// create database db1// use db1// 4. Now using the following commands create two tables where the second table has a foreign key reference to the first table as follows: drop table if exists course// create table course ( id int, courcename char(100) not null, duration int not null, primary key (id) ) engine=innodb// insert into course values(1,'system design',4), (2,'database system',6), (3,'operating system',16)// drop table if exists students// create table students ( id int not null, name char(100) not null, course_id int, foreign key (course_id) references course(id) on delete set null ) engine=innodb// insert into students values(1,'l',1), (2,'m',1), (3,'n',2),(4,'o',3),(5,'p',3),(6,'q',1)// 5. Now try to delete the foreign key with incorrect constraint name as follows: alter table students drop foreign key id// Expected Results: 1. Appropriate error should be displayed as the constraint name supplied does not exist. Actual Results: 1. Incorrect error is displayed as: "ERROR 1025 (HY000): Error on rename of '.\db1\students' to '.\db1\#sql2-1b0-57' (errno: 152)" [3 May 2005 14:05] Miguel Solorzano mysql> alter table students drop foreign key id// ERROR 1025 (HY000): Error on rename of '.\db1\students' to '.\db1\#sql2-45c-1' (errno: 152) mysql> select version(); -> // +------------------+ | version() | +------------------+ | 5.0.6-beta-debug | +------------------+ 1 row in set (0.00 sec) [30 Jun 2005 19:51] Kolbe Kegel This bug exists in 5.0.7 and is not platform specific.
