基于python+mysql超市信息管理系统（附完整源代码）

(参考的是这篇文章(5条消息) 数据库课程设计—超市零售信息管理系统（Python实现）_小桃在改bug的博客-CSDN博客_超市管理系统数据库设计但是这篇文章里没有完整的代码，所以我自己补全了ui界面和相关的代码，并进行了二创，框架也有改动，更主要的是写出来自己在编写过程中的一些错误，希望可以帮助排雷）

要源文件的太多了，最近在忙毕设没有时间，我在最后附上源代码了，按照我的文档就可以完成复现了（如果一定要源文件和实验报告的，【闲鱼】https://m.tb.cn/h.gUGBMiA?tk=Q4T2WBgzIlE MF7997 「我在闲鱼发布了【超市管理系统】

先放几张效果图

登录界面：

主界面：

添加信息界面：

添加员工信息界面：

输入一个示例数据并添加：

首先进行需求分析，想要做的是一个商城的信息管理系统（是一个类似大型的超市），可以帮助管理进货、销售、人员、库存信息，那么就要有进货，售货，员工，仓库，安全问题等方面的考虑，根据上述分析出下面的框架（由于空间有限，这是部分的框架图）

根据上面的分析绘制ER图，由于每次绘制时图形数量的限制，E-R图分三部分，通过带颜色的连接两个ER图

 根据上面的ER图进行逻辑结构设计消除依赖：

1.员工（员工编号，员工姓名，员工性别，员工年龄，员工工龄，员工电话，身份证号，工资，核酸情况）；

2.商品（商品编号，商品名称，商品类别，商品单价，商品成本，供货商）；

3.会员（会员卡卡号，会员姓名，电话，注册日期，累计金额，余额）；

4.供货商（供货商编号，供货商名称，供货商电话，供货商地址）；

5.仓库（仓库编号，仓库管理员编号，仓库名称，仓库地址）；

6.退货信息（交易流水号，商品编号，退货数量，退款金额，退货日期）；

7.销售（员工编号，商品编号，销售日期，销售数量，销售金额）；

8.购买（会员卡卡号，商品编号，购买日期，购买数量）；

9.供货（供货商编号，商品编号，供货日期，供货数量）；

10.库存（仓库编号，商品编号，库存量）；

11.安全问题（健康码，灭火器，自动灭火喷淋装置，检察人员编号）；

形成如下表：

员工表Staff

商品表Goods

会员表Member

供货商Vendor

仓库Ware

退货信息Infer

商品交易表Trade

入库信息表Entry

出库信息表Exits

安全问题Check1

下面附上我使用的版本python3.6+mysql8.0

1.需要手动在mysql 里创建一个数据库 sqlwork（什么名称都可以）

2.执行init.py进行初始化操作，也就是建表，插入初始数据，建立触发器，增加级联约束（之所以是这个顺序，是因为如果建表的时候就加入级联约束，外键约束就会导致插入数据失败）下面是init.py的代码

import pymysql   #数据库初始化 #创建表 connect = pymysql.connect(host="localhost", user="root",password="mysql", database="sqlwork")  # 建立连接 if connect:     print("连接成功!")  cursor = connect.cursor()   # 创建一个游标对象,python里的sql语句都要通过cursor来执行 #创建表及其约束 cursor.execute("create table Staff(Snum  varchar(10) primary key,Sname varchar(20) not null,Ssex varchar(5) check(Ssex in('男','女')),Sage int not null check(Sage>=18),Sseniority int not null check(Sseniority>=0),Sphone varchar(20) not null,Sid varchar(25) not null,Ssalary int check(Ssalary>=0),Syard varchar(20) check(Syard in('红码','黄码','绿码')) )") cursor.execute("create table Vendor(Vnum varchar(10) primary key,Vname varchar(10) not null,Vphone varchar(20) not null,Vpalce varchar(10) not null)") #

关闭游标 connect.close()  #初始化数据（两条数据或一条数据，为了后续增加约束） connect = pymysql.connect(host="localhost", user="root",password="mysql", database="sqlwork")  # 建立连接 cursor = connect.cursor()  # 创建一个游标对象,python里的sql语句都要通过cursor来执行 cursor.execute("insert into Goods values ('200001','薯片','零食',8,5,500,100,600,'100002')") cursor.execute("insert into Goods values ('200002','可乐','饮料',3,2,1000,100,1200,'100001')") cursor.execute("insert into Vendor values ('100001','可口','123456','杭州')") cursor.execute("insert into Vendor values ('100002','乐事','135790','西安')") cursor.execute("insert into Vendor values ('100003','牧场','246800','武汉')") cursor.execute("insert into Staff values ('0001','张三','男',30,5,'139820117','411481320301',5000,'绿码')") cursor.execute("insert into Staff values ('0002','熊大','女',32,3,'178883132','411481310302',3000,'绿码')") cursor.execute("insert into Member values ('300001','迪迦','179320118',20220830194422,1050,300,'321336')") cursor.execute("insert into Ware values('400001','一号','上海','0001')") cursor.execute("insert into Check1 values(20220620,'绿码','是','是')")   connect.commit()  # 提交 cursor.close() connect.close()  #创建触发器 满足顾客买商品的一个场景 connect = pymysql.connect(host="localhost", user="root",password="mysql", database="sqlwork")  # 建立连接 # 创建光标 cursor = connect.cursor() #购买的商品数量要在库存里减去 cursor.execute("create trigger update_Goods before insert on Trade for each row update Goods set Gstock=Gstock-new.Tamount where Gnum=new.Gnum;") #要在会员卡的总消费和余额里改变相应的数值 cursor.execute("create trigger update_Member before insert on Trade for each row update Member set Mtotal=Mtotal+new.Tmoney,Mbalance=Mbalance-new.Tmoney where Mnum=new.Mnum;") connect.commit() cursor.close() connect.close()  connect = pymysql.connect(host="localhost", user="root",password="mysql", database="sqlwork")  # 建立连接 cursor = connect.cursor()  cursor.execute("alter table Goods add foreign key(Vnum) references Vendor(Vnum) on delete cascade") cursor.execute("alter table Ware add foreign key(Snum) references Staff(Snum)") cursor.execute("alter table Trade add foreign key(Snum) references Staff(Snum)") cursor.execute("alter table Trade add foreign key(Gnum) references Goods(Gnum)") cursor.execute("alter table Trade add foreign key(Mnum) references Member(Mnum)") cursor.execute("alter table Infer add foreign key(Tnum) references Trade(Tnum)") cursor.execute("alter table Infer add foreign key(Gnum) references Goods(Gnum)") cursor.execute("alter table Entry add foreign key(Snum) references Staff(Snum)") cursor.execute("alter table Entry add foreign key(Gnum) references Goods(Gnum)") cursor.execute("alter table Entry add foreign key(Vnum) references Vendor(Vnum)") cursor.execute("alter table Exits add foreign key(Snum) references Staff(Snum)") cursor.execute("alter table Exits add foreign key(Gnum) references Goods(Gnum)")  connect.commit() # 关闭数据库连接，防止泄露 connect.close() 

3.接下来是主体部分（ui界面，sql查询）main.py代码如下（代码有1700行左右）

使用的是pymysql库实现数据库的连接以及相关sql语句执行操作

Tkinter库是用来实现ui界面，PIL库是用来放置图片背景使用

总体框架如下：

1. 登录界面      login（）
2. 主界面（增删改查）    mainpage（）
3. 选择界面（对哪个表进行增删改查的界面，4个）    如all_add（）
4. 对某个表进行操作的界面（40个左右，因为有10个表，每个表几乎都要增删改查）    如Staff_add（）
5. 40个具体的sql语句执行的函数    如add_Staff（）

在完成了数据库中表的初始化之后，就可以运行main.py函数，当然，在运行之前，要完成里面需要的python库的安装。

main.py：
