1、创建一个数据库StudentManage, 初始化大小10M,不足以1M每次增长
create database StudentManage
on
(
name = ‘StudentManage_data‘,
filename = ‘D:\StudentManage_data.mdf‘,
size = 10mb,
maxsize = 100mb,
filegrowth = 15%
)
log on
(
name = ‘StudentManage_log‘,
filename = ‘D:\StudentManage_log.ldf‘,
size = 2mb,
filegrowth = 1mb
)
2、其中表结构包括
学生信息表:StudentInfo
( 学生ID(主键),
所在班级ID(外键约束),
学生姓名(非空约束),
性别(检查约束(男,女)),
年龄(检查约束(6-30)),
身份证号(检查约束),
家庭地址(默认值‘地址不详’))
create table StudentInfo
(
StuId varchar(10) primary key,
ClassId varchar(8) foreign key references ClassInfo(ClassId),
StuName varchar(6) not null,
Sex varchar(4) default ‘男‘ check(Sex=‘男‘or Sex=‘女‘),
Age smallint check(Age>0 and Age<36),
IdNum char(18) check(IdNum like ‘[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9,X]‘),
StuAddress nvarchar(50) default ‘地址不详‘,
)
教师信息表:TeacherInfo
(教师ID(主键),
教师姓名(非空约束),
性别(检查约束(男,女)),
年龄(检查约束(25-60)),
身份证号(检查约束),
教学方向
家庭地址(默认值‘地址不详’))
create table TeacherInfo
(
TecId varchar(10) primary key,
TecName varchar(8) not null,
Sex varchar(4) default ‘男‘ check(Sex=‘男‘ or Sex=‘女‘),
Age smallint check(Age>25 and Age<60),
IdNum char(18) check(IdNum like ‘[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9,X]‘),
TecWhat nvarchar(8) not null,
TecAddress nvarchar(50) default ‘地址不详‘,
)
班级信息表:ClassInfo
(班级ID(主键),
班级名称(非空约束),
班级人数(15-60),
入校时间,
毕业时间
)
use StudentManage
create table ClassInfo
(
ClassId varchar(8) primary key,
ClassName varchar(8) not null,
CstuNum int,
InDate date,
GraduDate date
)
课程信息表:CourseInfo
(课程ID(主键),
课程名称(非空约束),
)
create table CourseInfo
(
CourId varchar(8) primary key,
CourName varchar(8) not null
)
考分信息表:Scores
(ID(标识列,(1, 1)),
学生ID(外键约束),
教师ID(外键约束),
考试批次,--第一次考还是补考?
分数(0-100)
)
create table ScoresInfo
(
ScoreId int primary key identity(1,1),
StuId varchar(10) foreign key references StudentInfo(StuId),
TecId varchar(10) foreign key references TeacherInfo(TecId),
PiCi varchar(8),
Score smallint check(Score>=0 and Score <=100)
)
3、以上的每个表至少加入3条以上的记录
use StudentManage
--向班级表插入三条数据
insert into ClassInfo
values(‘101‘,‘计算机‘,50,‘2010-09-09‘,‘2014-10-10‘)
insert into ClassInfo
values(‘102‘,‘嵌入式‘,50,‘2010-09-09‘,‘2014-10-10‘)
insert into ClassInfo
values(‘103‘,‘网络安全‘,50,‘2010-09-09‘,‘2014-10-10‘)
--向学生信息表里插入数据
insert into StudentInfo
values(‘144712190‘,‘101‘,‘武索普‘,‘男‘,18,‘411481199012102908‘,default)
insert into StudentInfo
values(‘144712221‘,‘102‘,‘路飞‘,‘男‘,18,‘211481199012102593‘,default)
insert into StudentInfo
values(‘144712321‘,‘103‘,‘罗宾‘,‘女‘,18,‘511481199012102908‘,default)
--向教师信息表里插入数据
insert into TeacherInfo
values(‘541001‘,‘白胡子‘,‘男‘,50,‘123456789098765432‘,‘震震大地‘,default)
insert into TeacherInfo
values(‘541002‘,‘罗利‘,‘男‘,50,‘323456789098765432‘,‘催眠掌‘,default)
insert into TeacherInfo
values(‘541003‘,‘帝喾克‘,‘女‘,26,‘523456789098765432‘,‘媚眼‘,default)
