Hi! don't think ON UPDATE is supported.
The manual : http://www.innodb.com/ibman.html doesn't mention anything about it except : Starting from version 3.23.50 you can also associate the ON DELETE CASCADE or ON DELETE SET NULL clause with the foreign key constraint. EG > When I try to change the id field in the parent table below, I get the > error: 1217 - Cannot delete a parent row; a foreign key constraint fails. > > What have I got wrong? Shouldn't it cascade the changes that were made to > the parent down to the child table? > > This is done with Mysql 3.23.50-max on Windows NT > > Here is the create that I am using for the test > > CREATE TABLE parent(id INT unsigned NOT NULL, PRIMARY KEY (id)) TYPE=INNODB; > create table child > ( > id int unsigned not null auto_increment > , parent_id int unsigned not null > , name varchar(20) null > , primary key (id) > , index parent_id(parent_id) > FOREIGN KEY (parent_id) REFERENCES parent(id) > ON UPDATE CASCADE > ) TYPE=INNODB; > > > Thanks in advance > > --------------------------------------------------------------------- > Before posting, please check: > http://www.mysql.com/manual.php (the manual) > http://lists.mysql.com/ (the list archive) > > To request this thread, e-mail <[EMAIL PROTECTED]> > To unsubscribe, e-mail <[EMAIL PROTECTED]> > Trouble unsubscribing?
