Answer 1

I got the same error, and since my case wasnt mentioned yet, i ll post this answer and hopefully it may save somebody's time!

My two tables engines, where different. The one was InnoDB, and the other MyIsam.

To change the engine of a table:

choose table, hit alter table, and then to hit that double arrow at the right-most of the Workbench(so it will point upwards).

Now change the engine!
