使用外键 SQL 向表中插入数据

Question

在为“Item”表的一行插入以下值后，我需要在“ItemBook”表中插入一些数据：

Name='Clippers', itemLink='amazon.com' description='hair clippers'  

现在我还想向 ItemBook 表中插入一些数据，但我不确定如何使用具有外键的表来执行此操作。下面是 SQL 代码：

CREATE TABLE Item (
Name VARCHAR(100) NOT NULL,
itemLink VARCHAR(100) NOT NULL,
description VARCHAR(1000) NOT NULL,
PRIMARY KEY (Name)
);

CREATE TABLE ItemBook (
ItemName VARCHAR(100) NOT NULL,
Publisher VARCHAR(100) NOT NULL,
PRIMARY KEY (ItemName),
FOREIGN KEY (ItemName) REFERENCES Item(Name)
);

我的尝试：

INSERT INTO itemBook (Name, Publisher)
VALUES ('Clippers', 'Bob');

错误信息：

Error Code: 1175. You are using safe update mode and you tried to update a table without a WHERE that uses a KEY column.  To disable safe mode, toggle the option in Preferences -> SQL Editor and reconnect.

其他尝试：

INSERT INTO eventbook (EventName, Publisher)
SELECT E.name
FROM event E
WHERE E.name = eventbook.EventName;

错误信息：

Error Code: 1054. Unknown column 'eventbook.EventName' in 'where clause'

是否有任何不使用整数 ID 的具体原因？我会做以下事情：

CREATE TABLE Item (
Id INTEGER NOT NULL IDENTITY PRIMARY KEY,
Name VARCHAR(100) NOT NULL,
itemLink VARCHAR(100) NOT NULL,
description VARCHAR(1000) NOT NULL,
);

CREATE TABLE ItemBook (
Id INTEGER NOT NULL IDENTITY PRIMARY KEY,
ItemName VARCHAR(100) NOT NULL,
Publisher VARCHAR(100) NOT NULL,
ItemId INTEGER NOT NULL,
FOREIGN KEY (ItemId) REFERENCES Item(Id)
);

INSERT INTO ItemBook Values(1, 'ItemName', 'Publisher', 0)

你有什么想法？

编辑 1. 根据您的回复和示例，我为 SQLITE 生成了以下 SQL（在其他数据库中也应该可以正常工作）

CREATE TABLE Item (
Name VARCHAR(100) NOT NULL,
ItemLink VARCHAR(100) NOT NULL,
Description VARCHAR(1000) NOT NULL,
PRIMARY KEY (Name)
);

CREATE TABLE ItemBook (
ItemName VARCHAR(100) NOT NULL,
Publisher VARCHAR(100) NOT NULL,
PRIMARY KEY (ItemName),
FOREIGN KEY (ItemName) REFERENCES Item(Name)
);

INSERT INTO Item (Name, ItemLink, Description) VALUES("Test Book", "http://www.testlink.com/", "This is a test book");

INSERT INTO ItemBook (ItemName, Publisher) Values("Test Book", "Test Publisher");

SELECT * FROM Item i JOIN ItemBook b on b.ItemName = i.Name
