Base de données de sélection des étudiants, tableau de données

–1. Créez une base de données nommée "Base de données 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. Utilisez l'opération pour créer la table "Student"

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. Utilisez des instructions T-SQL pour créer une table "cours".

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. Utilisez l'instruction T-SQL pour créer la table "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)
