Hi,
I am evaluating InnoDB's Foreign Keys and am stuck.
Using the sample tables I want to add records in the Child table with a NULL
parent_id (this being referenced to the Parent table) as follows:
CREATE TABLE parent(id INT NOT NULL,
PRIMARY KEY (id)) TYPE=INNODB;
CREATE
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 CASCADE) TYPE=INNODB;
OI!!! I'm going to
snip tables
OI!!! I'm going to sound like a complete ass now (I know) But since
when does MySQL support FOREIGN keys?? *gasp* MAN this is going to
make my life S much easier *curses at phpMyAdmin for not having the
option*
Do remember that this is only valid for mysql
