mysql创建数据库

创建一个名为Library:

CREATE DATABASE Library;

针对这个数据库，创建表

USE library;
CREATE TABLE student(
student_id INT(20) NOT NULL PRIMARY KEY auto_increment,
student_password CHAR NOT NULL, 
student_name CHAR NOT NULL,
student_major CHAR NOT NULL,
student_class CHAR NOT NULL,
gender CHAR
)

创建book表：

USE library;
CREATE TABLE book(
book_id INT(20) NOT NULL PRIMARY KEY auto_increment, 
book_name CHAR NOT NULL,
book_price CHAR NOT NULL
)
