建立JXGL和YGGL和Teachment数据库并插入数据

创建数据库JXGL

CREATE DATABASE JXGL

 建立student，course, sc表

USE JXGL
CREATE TABLE Student
(
	Sno char(10) NOT NULL PRIMARY KEY,
	Sname char(8) NOT NULL,
	Ssex char(2) NOT NULL,
	Sage smallint,
	Sdept char(10),
	)

USE JXGL
CREATE TABLE Course
(
	Cno char(4) PRIMARY KEY,
	Cname char(40) NOT NULL,
	Cpno char(4),
	Ccredit smallint,
	)
USE JXGL
CREATE TABLE SC
(
	Sno char(10), 
	Cno char(4),
	Grade smallint,
	CONSTRAINT PK_SC PRIMARY KEY(Sno, Cno),
	FOREIGN KEY(Sno) REFERENCES Student(Sno),
	FOREIGN KEY(Cno) REFERENCES Course(Cno),
	)

分别向三张表中插入数据

--向Student表中插入数据
INSERT INTO Student
values ('201215121', '李勇', '男', 20, 'CS'),
	   ('201215122', '刘晨', '女', 19, 'CS'),

	)

--建立Rank表
USE YGGL
CREATE TABLE Rank

为了省事，已将代码模板复制到上面，有的需要稍作修改。根据实验要查询的操作可以适当修改插入数据，以达到查询效果 。如果你不会建表插数据等，请不要直接copy，用手一个一个打出来
