Hi all,
It seems that some is misunderstanding my problem, so i try to re-write my problem
again.
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 like
this:
insert into parent values (1);
insert into parent values (2);
and 1,1 and 1,6 in the child table, like this:
insert into child values (1,1);
insert into child values (1,6);
, it still works !!!!!!
What i know, is that the constraint is voilated if i insert the last insert statement
(insert into child values (1,6)), because 6 is NOT in the parent table!!!!
BTW: Any value is accepted in the child table - Thats Strange!!!
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 J�rgensen
