Dear friend,
Take a look,carefully, about how are create tables;
All fields are INTeger type.Do a "select * from child;" to see what values
are stored in tables....for your curiosity.

Good luck,
Gelu

Subject: Constraints - Error or Bug????


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
