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 179 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 shou

Laravel Drop Foreign Key
alter a table in such a way that it would break a foreign key constraint: alembic drop foreign key 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 http://stackoverflow.com/questions/160233/what-does-mysql-error-1025-hy000-error-on-rename-of-foo-errorno-150-me 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 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 more information, please refer tothis link. Workaround Temporarily disable the foreign key constraints check when altering the table collation by executing the following queries before and after the alter attempt itself: Disable Foreign Key Constraints SET FOREIGN_KEY_CHECKS=0; Reattempt to change the collation and character set for a particular table ALTER TABLE `tableName` CHARACTER SET utf8 COLLATE utf8_bin Enable back the Foreign Key Constraints SET FOREIGN_KEY_CHECKS=1; Please do take note to generate a full backup of your Confluence database before then proceed with the suggested workaround as preventive measures.
