在python中创建动态插入查询以将数据保存到mysql db中。

pip install mysql-connector-python

import mysql.connector

# 建立数据库连接
cnx = mysql.connector.connect(user='your_username', password='your_password',
                              host='your_host', database='your_database')
cursor = cnx.cursor()

# 创建表
create_table_query = '''
CREATE TABLE IF NOT EXISTS users (
    id INT AUTO_INCREMENT PRIMARY KEY,
    name VARCHAR(255),
    age INT
)
'''
cursor.execute(create_table_query)

# 插入数据
insert_query = '''
INSERT INTO users (name, age) VALUES (%s, %s)
'''
data = ('John', 25)
cursor.execute(insert_query, data)

# 提交更改
cnx.commit()

# 提交更改
cnx.commit()

# 关闭连接
cursor.close()
cnx.close()
