sqlserver創建表實例

創建表語句，用案例說話

創建這四個表，並插入信息
學生（學號，姓名，年齡，性別，所在系）
課程（課程號，課程名，先行課，學分）
選課（學號，課程號，成績）
系部（系號，系名稱，系主任）

create database Test;	//創建數據庫Test
//建表的順序不能該表Department->Cource->Student->SCource
create table Department(	//系部表
	DNo		int,
	DName		nchar(10),
	DHost		nchar(10),
	primary key(DNo),		//設置DNo爲主鍵
);
create table Cource(	//課程表
	CNo		int	,
	CName		nchar(10),
	PreCource		nchar(10),
	TGrade		int,
	primary key(Cno),
);
create table Student(	//學生表，由於學生表需要對系部表關聯，所以先創建系部表
	SNo		int	,
	SName		nchar(10),
	SAge		int,
	SSex		nchar(2),
	SDept		int,
	primary key(SNo),
	foreign key(SDept) references Department(DNo),	//設置SDept爲DNo的外鍵
);
create table SCource(	//選課表,同理要建在學生表與課程表之下
	SNo		int,
	CNo		int	,
	Grade		int,
	primary key(SNo,Cno),
	foreign key(SNo) references Student(SNo),
	foreign key(CNo) references Cource(CNo),
);
