8 down vote accepted The most likely your mycolumn is a part of a foreign key. If so, you have to remove the constraint, then change type for the both primary/foreign key and then add constraint again. share|improve this answer answered Oct 1 '12 at 12:56 Maksym Polshcha 8,65342951 I just ran into a similar problem (going from an INT to a BIGINT). I decided to duplicate the table (which had a foreign key constraint on the column I needed to change) and its content, change the column type in the duplicate table without issue, and then replaced the original table with the duplicate table. Is that a dangerous thing to do? –tylerl Jun 11 '14 at 19:31 @tylerl No, if the data on the original table remains unchanged during your changes. Otherwise you can have data loss/inconsistency. –Maksym Polshcha Jun 12 '14 at 8:02 Yeah I believe it broke things in my app... Something must have not copied over right when the table was duplicated (I'm using Sequel Pro on a Mac)? I don't think any data was lost, but suddenly my server didn't feel like saving data to a particular table anymore! Weird... The problem is that I had made a note that the field in question was a foreign key in a particular table, but I can't find the FK constraint! Grrrr.... –tylerl Jun 12 '14 at 18:44 Anybody knows of any tool that is able to automate this? For a large d

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 181 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, iss
