又是周六，又是磨蹭个一上午~午饭后开始吧

1、MySQL

-----子查询与连接（三）-----

----使用INSERT...SELECT插入记录

--数据库内容的英文版本

由于我的WAMP中的MYSQL控制台显示中文无力，在更改过程中心力交瘁，遂改变战术，把数据改为了全英文的，现分享出来

-- 创建数据表

CREATE TABLE IF NOT EXISTS goods(
goods_id SMALLINT UNSIGNED PRIMARY KEY AUTO_INCREMENT,
goods_name VARCHAR(150) NOT NULL,
goods_cate VARCHAR(40) NOT NULL,
brand_name VARCHAR(40) NOT NULL,
goods_price DECIMAL(15,3) UNSIGNED NOT NULL DEFAULT 0,
is_show BOOLEAN NOT NULL DEFAULT 1,
is_saleoff BOOLEAN NOT NULL DEFAULT 0
);

-- 写入记录
