+Goods 数据库中有一个表：
+
+```mysql
+create table book(
+    id int primary key auto_increment,
+    title varchar(200) not null ,
+    description varchar(1000) default '',
+    price decimal(12, 4),
+    isbn char(16) not null ,
+    publish_at date not null 
+);
+create unique index idx_book_isbn on book(isbn);
+```
+
+那么下列哪个选项的代码可以执行成功？
+
+## 答案
+
+```mysql
+insert into book(title, price, isbn, publish_at) select 'a book title', 25.4, 'xx-xxxx-xxxx', '2019-12-1';
+insert into book(title, price, isbn, publish_at) select 'a other book title', 25.4, 'yy-yyyy-xxxx', '2019-12-1'; 
+```
+
+## 选项
+
+### 唯一键冲突
+
+```mysql
+insert into book(title, price, isbn, publish_at) select 'a book title', 25.4, 'xx-xxxx-xxxx', '2019-12-1';
+insert into book(title, price, isbn, publish_at) select 'a other book title', 35.4, 'xx-xxxx-xxxx', '2019-12-1'; 
+```
+
+### 缺少必要的列
+
+```mysql
+insert into book(price, isbn, publish_at) select 25.4, 'xx-xxxx-xxxx', '2019-12-1';
+insert into book(price, isbn, publish_at) select 35.4, 'yy-yyyy-xxxx', '2019-12-1';
+```
+
+### 类型错误
+
+```mysql
+insert into book(title, price, isbn, publish_at) select 'a book title', 'unknown', 'xx-xxxx-xxxx', '2019-12-1';
+insert into book(title, price, isbn, publish_at) select 'a other book title', 'unknown', 'xx-xxxx-xxxx', '2019-12-1';
+```
+
+### 违反非空约束
+
+```mysql
+insert into book(title, price, isbn, publish_at) select null, 'unknown', 'xx-xxxx-xxxx', '2019-12-1';
+insert into book(title, price, isbn, publish_at) select null, 'unknown', 'xx-xxxx-xxxx', '2019-12-1';
