如何利用MySQL和Python开发一个简单的在线投诉管理系统

pip install mysql-connector-python

CREATE TABLE complaints (
    id INT PRIMARY KEY AUTO_INCREMENT,
    customer_name VARCHAR(255),
    customer_email VARCHAR(255),
    complaint_subject VARCHAR(255),
    complaint_message TEXT,
    complaint_date TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);

import mysql.connector

# 创建数据库连接
mydb = mysql.connector.connect(
    host = "localhost",
    user = "root",
    password = "your_password",
    database = "your_database"
)

# 创建数据库游标
mycursor = mydb.cursor()

# 获取用户输入
customer_name = input("请输入您的姓名：")
customer_email = input("请输入您的邮箱：")
complaint_subject = input("请输入投诉主题：")
complaint_message = input("请输入投诉内容：")

# 插入数据到表中
sql = "INSERT INTO complaints (customer_name, customer_email, complaint_subject, complaint_message) VALUES (%s, %s, %s, %s)"
val = (customer_name, customer_email, complaint_subject, complaint_message)
mycursor.execute(sql, val)

# 提交更改
mydb.commit()

# 输出成功信息
print("投诉已成功提交！")

# 查询数据表中的所有投诉信息
mycursor.execute("SELECT * FROM complaints")

# 获取查询到的所有结果
results = mycursor.fetchall()

# 输出查询结果
for result in results:
    print(result)

# 获取用户输入
complaint_subject = input("请输入要查询的投诉主题：")

# 根据条件查询数据
sql = "SELECT * FROM complaints WHERE complaint_subject = %s"
val = (complaint_subject,)
mycursor.execute(sql, val)

# 获取查询结果
results = mycursor.fetchall()

# 输出查询结果
for result in results:
    print(result)
