Python餐饮管理系统

一、前期准备：

1.安装pymssql库
2.配置好SQL Server端口(在SQL配置管理器那里配置，具体可以参考java端口配置)，这个有点难哦~多去搜搜。
3.建立数据库，建立表格
4.弄一个好键盘不然敲着不舒服哈哈哈哈哈哈哈~

二、题目

三、代码如下：

四、运行结果

五、建立的数据库和数据库表

1、三个表，分别为

当然如果你想让你的功能更丰富你可以多加几个表，同时增加一些触发器(表之间的联系)啥的，让它看着更完善。

2、设计表

1.菜品表

2.订单细节表
注：这个不需要自己添加内容。。

3.桌台表

注：附送测试数据库的连接代码

（可以先创建一个 python文件 用来先测试一下数据库有没有连接上）
配置端口的全都选"启用”，全都选"是"就行了，配置好后重启电脑就可以使用连接代码啦~

import pymssql #引入pymssql模块

def conn():
    connect = pymssql.connect('(local)', 'sa', '12345', 'shujukuming') #服务器名,账户,密码,数据库名
    if connect:
        print("连接成功!")
    return connect
    
if __name__ == '__main__':
    conn = conn()
