在SQL Server2005中用語句創建數據庫和表：
具體示例如下：
use master
go
if exists (select * from sysdatabases where name='Study')
--判斷Study數據庫是否存在，如果是就進行刪除
drop database Study
go
EXEC sp_configure 'show advanced options', 1
GO
-- 更新當前高級選項的配置信息
RECONFIGURE
GO
EXEC sp_configure 'xp_cmdshell', 1
GO
-- 更新當前功能(xp_cmdshell)的配置信息。
RECONFIGURE
GO
exec xp_cmdshell 'mkdir D:data', NO_OUTPUT
--利用xp_cmdshell 命令創建文件夾，此存儲過程的第一個參數為要執行的有效dos命令，第二個參數為是否輸出返回信息。
go
create database Study--創建數據庫
on primary
(
name='Study_data',--主數據文件的邏輯名
fileName='D:dataStudy_data.mdf',--主數據文件的物理名
size=10MB,--初始大小
filegrowth=10% --增長率
)
log on
(
name='Study_log',--日志文件的邏輯名
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')--判斷是否存在此表
drop table Student
go
create table Student
(
id int identity(1,1) primary key,--id自動編號，並設為主鍵
[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())--計算列。
)
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')),--檢查約束，性別必須是男或女
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),--外鍵約束，引用Team表的主鍵
constraint DF_remark default('請在這裡填寫備注') for remark--默認約束，
go
alter table Team
add
constraint UK_captainId unique(captainId)--唯一約束
go
insert into Team values('第一組',1)
insert into Team values('第二組',2)
insert into Team values('第三組',3)
insert into Team values('第四組',4)
insert into Team values('第五組',5)
insert into Student values('小強','男','1982-6-9','23456789451','來自河北',1)
insert into Student values('小昭','男','1987-6-9','78945678945','山東',4)
insert into Student values('小溪','男','1982-6-9','65987845651','撫順',3)
insert into Student values('小憐','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)
)
