Hibernate cascade and mysql foreign key
CREATE TABLE student (
id INTEGER UNSIGNED NOT NULL AUTO_INCREMENT PRIMARY KEY,
teacher INTEGER UNSIGNED NOT NULL,
name varchar(12) BINARY NOT NULL,
sex TINYINT NOT NULL DEFAULT 0,
FOREIGN KEY fk_teacher (teacher) REFERENCES teacher(id)
ON UPDATE CASCADE
ON DELETE CASCADE
id INTEGER UNSIGNED NOT NULL AUTO_INCREMENT PRIMARY KEY,
teacher INTEGER UNSIGNED NOT NULL,
name varchar(12) BINARY NOT NULL,
sex TINYINT NOT NULL DEFAULT 0,
FOREIGN KEY fk_teacher (teacher) REFERENCES teacher(id)
ON UPDATE CASCADE
ON DELETE CASCADE
) engine=INNODB;
If we set "ON UPDATE/DELETE CASCADE" on a foreign key, it is the same effect with configure hibernate CASCADE.
But if we set Hibernate cascade and foreign key cascade at the same time, then our project will use hibernate cascade first.
