You must create the key (sku), it is not created for you.

I would appreciate some help with a problem. I'm trying to create two
tables that have referential integrity.
If I try and create the following table it works fine:

CREATE TABLE book
(
 sku INT
) TYPE=INNODB;
However, if I creating  this table, I get an error:

CREATE TABLE book
(
 sku INT,
 FOREIGN KEY (sku) REFERENCES stock_item (sku) ON DELETE CASCADE
) TYPE=INNODB;
The error is: ERROR 1005: Can't create table './shop/book.frm' (errno:
150)  

The parent table is as follows:

CREATE TABLE stock_item
(
 sku CHAR(14) NOT NULL,
 PRIMARY KEY (sku),
 description TEXT,
 publisher_id INT DEFAULT NULL,
 pub_date DATE DEFAULT NULL,
 type ENUM('OT','BK','CD') NOT NULL,
 availability_id TINYINT DEFAULT NULL,
 image_id INT DEFAULT NULL,
 buy_price FLOAT UNSIGNED,
 list_price FLOAT UNSIGNED,
 sell_price FLOAT UNSIGNED,
 discount TINYINT UNSIGNED,
 stock_count MEDIUMINT UNSIGNED NOT NULL DEFAULT 0,
 display ENUM('no','yes') DEFAULT 'no'
) TYPE=INNODB;
Any suggestions would be welcome.

Thanks

Tom
