demo 1:

--新数据库

create database spdb1

--创建dept表

create table dept
(
deptno int primary key,
dname varchar(30),
loc varchar(30)
)
;
--创建emp表

create table emp

(empno int primary key,
ename nvarchar(30),
job nvarchar(30),
mgr int,
hiredate datetime,
sal numeric(10,2),
comm numeric(10,2),
deptno int foreign key references dept(deptno) --因为deptno我们根据需要做成外键

)

--针对外键,请注意

--①外键只能指向主键

--②外键和主键的数据类型要一致

--首先建立dept表,因为dept表与emp表存在约束

insert into dept values(10,'ACCOUNTING','NEW YORK')
/
insert into dept values(20,'RESEARCH','DALLAS')
/
insert into dept values(30,'SALES','CHICAGO')
/
insert into dept values(40,'OPERATIONS','BOSTON')
/
--建立emp表

// Declare a variable named htmldb_delete_message
