+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
