MySQL : ERROR 1215 (HY000): Cannot add foreign key constraint

Question

I have read Database system concepts, 6th edition, Silberschatz. I\'m going to implement the university database system shown in chapter 2 on OS X

Answer 1

I don't meet the problem as you. But I get the same ERROR Message. So I mark it down here for others' convience.

Check the charset of two table if the column type is char or varchar. I use a charset=gbk, but I create a new table whose default charset=utf8. So the charset is not the same.

ERROR 1215 (HY000): Cannot add foreign key constraint

To solve it is to use the same charset. For example utf8.
