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

CONSTRAINT vendor_tbfk_1 FOREIGN KEY (V_CODE) REFERENCES vendor (V_CODE) ON UPDATE CASCADE

this is how it could be... look at the referencing column part. (V_code)
