student(学生表)、teacher(教师表)、course(课程表)、sc(分数表)
2、创建表
create table student(
sno varchar2(10) primary key,
sname varchar2(20),
sage number(2),
ssex varchar2(5)
)
create table teacher(
tno varchar2(10) primary key,
tname varchar2(20)
)
create table course(
cno varchar2(10),
cname varchar2(20),
tno varchar2(20),
constraint pk_course primary key (cno,tno)
)
create table sc(
sno varchar2(10),
cno varchar2(10),
score number(4,2),
constraint pk_sc primary key (sno,cno)
)
3、插入初始化数据
/*******初始化学生表的数据******/
insert into student values ('s001','张三',23,'男')
insert into student values ('s002','李四',23,'男')
