Problem somewhat solved:
I am somewhat thrown by what I stumbled across, but it has to do with the "_"
underscore character. If I run the same below script without the "_", it works
fine. But as soon as I put in the underscore "_" it fails with the error.
This sounds pretty insane? They are definitely different names?
Does anyone have input into this?
Thanks,
CREATE TABLE menu_sequence (id INT NOT NULL);
insert into menu_sequence VALUES (0);
CREATE TABLE MENU_GROUP(id INT NOT NULL,
PRIMARY KEY (id)
) TYPE=INNODB;
CREATE TABLE MENU_GROUPREL(id INT, parent_id INT,
INDEX par_ind (parent_id),
FOREIGN KEY (parent_id) REFERENCES parent(id)
ON DELETE CASCADE
) TYPE=INNODB;

Subject: RE: Cascade problem now error:
Thanks for the info on the command line util. I am new and was unaware of it.
But anyway, I have gone through the docs many more times, and I cannot figure
out where my problem is. Of course the error is a foreign key problem, but I do
not see where. I even am basically using a textbook example here that fails
with the same error:
If someone see a problem, please let me know, I am creating a fresh database
and just running those 30 or so lines below, and it errors with this:
ERROR 1005: Can't create table '.\builder\menu_group_rel.frm' (errno: 150)
