在SQL Server2005中用语句创建数据库和表:
具体示例如下:

use master

go

if exists (select * from sysdatabases where name='Study')

--判断Study数据库是否存在,如果是就进行删除

drop database Study

go

EXEC sp_configure 'show advanced options', 1

GO

-- 更新当前高级选项的配置信息

RECONFIGURE

GO

EXEC sp_configure 'xp_cmdshell', 1

GO

-- 更新当前功能(xp_cmdshell)的配置信息。

RECONFIGURE

GO

exec xp_cmdshell 'mkdir D:data', NO_OUTPUT

--利用xp_cmdshell 命令创建文件夹,此存储过程的第一个参数为要执行的有效dos命令,第二个参数为是否输出返回信息。

go

create database Study--创建数据库

on primary

(

name='Study_data',--主数据文件的逻辑名

fileName='D:dataStudy_data.mdf',--主数据文件的物理名

size=10MB,--初始大小

filegrowth=10% --增长率

)

log on

(

name='Study_log',--日志文件的逻辑名

fileName='D:dataStudy_data.ldf',--日志文件的物理名

size=1MB,

maxsize=20MB,--最大大小

filegrowth=10%

)

go

use Study

go

if exists (select * from sysobjects where name='Student')--判断是否存在此表

drop table Student

go

create table Student

(

id int identity(1,1) primary key,--id自动编号,并设为主键

[name] varchar(20) not null,

sex char(2) not null,

birthday datetime not null,

phone char(11) not null,

remark text,

tId int not null,

age as datediff(yyyy,birthday,getdate())--计算列。

)

go

if exists (select * from sysobjects where name='Team')

drop table Team

go

create table Team

(

id int identity(1,1) primary key,

tName varchar(20) not null,

captainId int

)

go

alter table Student

add

constraint CH_sex check(sex in ('男','女')),--检查约束,性别必须是男或女

constraint CH_birthday check(birthday between '1950-01-01' and '1988-12-31'),

constraint CH_phone check(len(phone)=11),

constraint FK_tId foreign key(tId) references Team(id),--外键约束,引用Team表的主键

constraint DF_remark default('请在这里填写备注') for remark--默认约束,

go

alter table Team

add

constraint UK_captainId unique(captainId)--唯一约束

go


insert into Team values('第一组',1)

insert into Team values('第二组',2)

insert into Team values('第三组',3)

insert into Team values('第四组',4)

insert into Team values('第五组',5)


insert into Student values('小强','男','1982-6-9','23456789451','来自河北',1)

insert into Student values('小昭','男','1987-6-9','78945678945','山东',4)

insert into Student values('小溪','男','1982-6-9','65987845651','抚顺',3)

insert into Student values('小怜','男','1981-6-9','25487965423','天津',5)

insert into Student(name,sex,birthday,phone,tId) values('李真','男','1984-6-9','25487965423',5)


select * from Team

select * from Student


if exists (select * from sysobjects where name='teacher')

drop table teacher

go

 

create table teacher

(

id int identity (1,1) primary key,

name varchar(20),

address varchar(20)

)


go
