为什么我插入的值在生成报告时没有显示在报告上？

Question

当我尝试生成整个代码时，我收到错误代码 1050 表“sakila.jrey_author”已存在，当我尝试单独生成报告时，它可以工作，但它只生成表中列的名称。 （免责声明：这些不是表格的原始名称，我对其中的一些个人信息感到不舒服）

   create table sakila.jrey_author (
   author_id int,
   author_name VARCHAR(50),

SELECT *

SELECT *

SELECT *

我尝试查看是否错误地插入了数据，因此我通过在值之前添加列的全名来更改“插入表名称值”，但它给了我相同的结果。

Answer 1

Sakila 是由 Mike Hillyer 开发的 MySQL 示例数据库。
查看 MySQL 文档了解详细信息。

您收到错误：

Error Code 1050 table 'sakila.jrey_author' already exist 

因为您没有删除现有的

Sakila

数据库表。

所以，先删除表，然后创建 使用顶部的查询：

DROP TABLE IF EXISTS sakila.jrey_author;
DROP TABLE IF EXISTS sakila.jrey_books;
DROP TABLE IF EXISTS sakila.jrey_member;
DROP TABLE IF EXISTS jrey_borrowedbooks;
DROP TABLE IF EXISTS sakila.jrey_transaction;

接下来更正您的数据。我发现有很多数据问题如下：

1. 从

   MM/DD/YYYY

   到

   YYYY-MM-DD

   （标准格式）的正确日期格式。
2. 检查 Columndata 类型及其插入值，如下所示：

3. sakila.jrey_books

   表的列

   PublisherID INT

   数据在

   insert query

   中不可用（检查图像）

好的，我做了一些正确的事情并且它工作正常。 这是完整的代码：
