Banco de dados eletivo do aluno, tabela de dados

-1. Crie um banco de dados chamado "Banco de dados Studentxuanke"

CREATE DATABASE xuanke
ON  PRIMARY 
( NAME = 'xuanke_data', 
  FILENAME = 'E:\Professional flie\SQL file\database\xuanke\xuanke_data.mdf' , 
  SIZE = 5120KB , MAXSIZE = 15360KB , 
  FILEGROWTH = 20%)
 LOG ON 
( NAME = 'xuanke_log', 
  FILENAME = 'E:\Professional flie\SQL file\database\xuanke\xuanke_log.ldf' , 
  SIZE = 5120KB , MAXSIZE = 10240KB , 
  FILEGROWTH = 1024KB )

-2. Use a operação para criar a tabela "Aluno"

CREATE TABLE Student
(
	Sno nchar(10) PRIMARY KEY,
	Sname nchar(10),
	Ssex nchar(10),
	Sbirthday datetime 
)

INSERT INTO Student
(Sno ,	Sname ,Ssex ,Sbirthday)
VALUES
('090101','汪涵','男','1990-1-1')

INSERT INTO Student
(Sno ,	Sname ,Ssex ,Sbirthday)
VALUES
('090102','刘洁','女','1991-3-4')

INSERT INTO Student
(Sno ,	Sname ,Ssex ,Sbirthday)
VALUES('090103','刘莉莉','女','1992-5-6')

-3 Use as instruções T-SQL para criar uma tabela de "cursos".

CREATE TABLE Course
(
   Cno nchar(10) PRIMARY KEY,
   Cname   nchar(10),
   Score     real,
   Xcno nchar(10)
)

INSERT INTO Course
(Cno,Cname,Score,Xcno)
VALUES
('C001','C语言',2,'')

INSERT INTO Course
(Cno,Cname,Score,Xcno)
VALUES
('C002','数据结构',2,'C001')

INSERT INTO Course
(Cno,Cname,Score,Xcno)
VALUES
('C003','数据库原理',2,'')

-4 Use a instrução T-SQL para criar a tabela "xuanke".

CREATE TABLE xuanke
(
	Sno nchar(10) ,
	Cno nchar(10) ,
	Result real 
	PRIMARY KEY(Sno,Cno)
)

INSERT INTO xuanke
(Sno,	Cno,Result) 
VALUES
('090101','C001',78)

INSERT INTO xuanke
(Sno,	Cno,Result) 
VALUES
('090101','C002',87)

INSERT INTO xuanke
(Sno,	Cno,Result) 
VALUES
('090102','C001',97)

INSERT INTO xuanke
(Sno,	Cno,Result) 
VALUES
('090102','C002',79)

INSERT INTO xuanke
(Sno,	Cno,Result) 
VALUES
('090102','C003',56)

INSERT INTO xuanke
(Sno,	Cno,Result) 
VALUES
('090103','C001',55)
