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 6,4601365131 answered Nov 2 '10 at 18:50 Ike Walker 33.4k95278 add a comment| up vote 18 down vote For those who are getting to this question via goo

Mysql Rename Foreign Key
cryptic error message, “Error on rename,” when you try to alembic drop foreign key alter a table in such a way that it would break a foreign key constraint:

It is http://www.xaprb.com/blog/2006/08/22/mysqls-error-1025-explained/ 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.

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 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.
