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 KEY (country_id) REFERENCES country (id) ON DELETE NO ACTION ON UPDATE NO ACTION Now simply issue an: alter table region drop foreign key region_ibfk_1; And finally an: alter table region drop column country_id; And you are good to go! share|improve this answer answered Apr 11 '11 at 0:45 Jeshurun 13.2k44869 7 If I could upvote this twice I would.

Right now it has a primary key like this: PRIMARY http://stackoverflow.com/questions/4080611/1025-error-on-rename-of-database-sql-2e0f-1254ba7-to-database-table KEY (user_id, round_number) Where user_id is a foreign key. I am trying to change it to this: PRIMARY KEY (user_id, round_number, created_at) I am doing this in phpmyadmin by clicking on the primary key icon in the table structure view.

To find out which table caused the error you can run SHOW ENGINE INNODB

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. 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 ...
