no foreign key in table if engine is MyISAM

Question

why i cannot create foreign key in my table payments.

crate table students(
text char(5)NOT NULL,
id int(11)NOT NULL AUTO_INCREMENT,
name varchar(250),
level var         


        

Answer 1

Because MyISAM does not support foreign keys. The FK declarations are parsed, but otherwise ignored. You need to use InnoDB tables for real FK support.
