Hi all,
I just wonder. I have tried this example from www.mysql.org Doc.
CREATE TABLE parent(id INT NOT NULL, PRIMARY KEY (id)) TYPE=INNODB;
CREATE TABLE child(id INT, parent_id INT, INDEX par_ind (parent_id),
FOREIGN KEY (parent_id) REFERENCES parent(id)
ON DELETE SET NULL
) TYPE=INNODB;
But, the constraint does not work propperly. If i add 1 and 2 in the parent table, and
1,1 and 1,6 in
the child table, it still works.
Does anyone know if there is a Bug in the mysql, or im just getting it all wrong????
If you know howto make the constraints work please write a little example - Thanks :-)
Regards
Frank Jørgensen
