数据库课程设计_购书管理系统（sql_c#及sql_java）

已完成两种语言操作sql server的课设，将陆续将代码发布，本人菜鸡，大佬勿喷。

 

1：几个表的创建，在sql的查询里面写

CREATE TABLE BookCentermessage(

--Sno int PRIMARY KEY,--设置主键

BookCentercode varchar(10) NULL,

BookCentername varchar(10) NULL,

manager varchar(10) NULL,

fare int NULL,

)

 

CREATE TABLE department(

--Sno int PRIMARY KEY,--设置主键

departmentcode varchar(10) NULL,

departmentmanagername varchar(10) NULL,

departmentmanagerdirectory varchar(10) NULL,

departmentmanagerphone varchar(10) NULL,

departmentfare int NULL,

)

 

CREATE TABLE departmentnumber(

numbercode varchar(10) PRIMARY KEY,

numbername varchar(10) NULL,

numberage varchar(10) NULL,

numbersex varchar(1) NULL,

numberzhiwe varchar(10) NULL,

numbersalary int NULL,

departmentcode varchar ,

)

 

CREATE TABLE book(

bookcode varchar(10) PRIMARY KEY,

bookname varchar(10) NULL,

purchasecosting int NULL,

sellfare int NULL,

buyfare varchar(10) NULL,

departmentcode varchar(10) ,
)

 

CREATE TABLE publication(

publicationcode varchar(10) NULL,

publicationcname varchar(10) NULL,

publicationdirectory varchar(10) NULL,

publicationphone varchar(10) NULL,

book varchar(10),

bookname varchar(10),

)

 

CREATE TABLE warehouse(

warehousecode varchar(10) NULL,

warehousemanagercname varchar(10) NULL,

warehousemanagerphone varchar(10) NULL,

warehousefare int NULL,

bookcoder varchar(10) NULL,

)

 

2 约束条件

防止一些数据的损坏及方便数据更新，添加约束。

ALTER TABLE departmentnumber
add constraint FK_departmentnumber_department foreign key(departmentcode) references department(departmentcode)

 

ALTER TABLE book
add constraint FK_book_department foreign key(departmentcode) references department(departmentcode)

 

ALTER TABLE book
add constraint FK_book_publication foreign key(bookcode) references publication(bookcode)

 

ALTER TABLE prifit
add constraint FK_prifit_publication foreign key(bookcode) references publication(bookcode)

一些基本的查询操作

select sellfare
from book
where buyfare <=30

 

select numbername,numbercode,numbersalary
from departmentnumber
where numbername IN ('小王')

 

update department set departmentmanagerdirectory='14号楼620' where departmentmanagerdirectory='14号楼619'

 

insert into publication (publicationcode,publicationcname,publicationdirectory,

publicationphone,bookcode,bookname) values(04,'一德儿',619,123125,004001,'日语')

 

update book set sellfare=100 where bookname='高数'

 

insert into departmentnumber(numbercode,numbername,numberage,numbersex,numberzhiwe,numbersalary,departmentcode) values(006002,'朱翔龙',20,'T','销售',3000,'005')

 

delete from departmentnumber where numbername='小刘'

使用c#创建窗体框进行操作。（详细讲创建步骤）

（1）：打开visual studio创建
