利用pycharm在mysql中，创建school数据库，school数据库中再创建student表，teacher表，分别插入三条数据；再创建一个mysql连接，并进行输出查看的代码

首先，确保你已经安装了MySQL服务器，并且PyCharm中配置了Python环境以及相关的数据库驱动（如`mysql-connector-python`或`pymysql`）。

以下是使用Python和PyCharm操作MySQL的步骤：

1. 打开PyCharm，创建一个新的Python项目。
2. 安装MySQL驱动，可以在PyCharm的Terminal中使用pip命令安装，如：`pip install mysql-connector-python`。
3. 创建`school`数据库。
4. 在`school`数据库中创建`student`表和`teacher`表。
5. 向这两个表中各插入三条数据。
6. 使用Python连接到MySQL数据库，执行查询并输出结果。

以下是一个简单的代码示例：

import mysql.connector
from mysql.connector import Error

# 创建数据库连接
def create_server_connection(host_name, user_name, user_password):
    connection = None
    try:
        connection = mysql.connector.connect(
            host=host_name,
            user=user_name,
            passwd=user_password
        )
        print("MySQL Database connection successful")
    except Error as err:
        print(f"Error: '{err}'")

    return connection

# 创建数据库
def create_database(connection, query):
    cursor = connection.cursor()
    try:
        cursor.execute(query)
        print("Database created successfully")
    except Error as err:
        print(f"Error: '{err}'")

# 创建表
def create_table(connection, query):
    cursor = connection.cursor()
    try:
        cursor.execute(query)
        print("Table created successfully")
    except Error as err:
        print(f"Error: '{err}'")

# 插入数据
def insert_data(connection, query):
    cursor = connection.cursor()
    try:
        cursor.execute(query)
        connection.commit()
        print("Data inserted successfully")
    except Error as err:
        print(f"Error: '{err}'")

# 查询数据并打印
def query_data(connection, query):
    cursor = connection.cursor()
    try:
        cursor.execute(query)
        records = cursor.fetchall()
        for row in records:
            print(row)
    except Error as err:
        print(f"Error: '{err}'")

# 主函数
def main():
    host_name = "localhost"
    user_name = "root"
    user_password = "your_password"  # 替换为你的MySQL root用户密码

    connection = create_server_connection(host_name, user_name, user_password)

    # 创建school数据库
    create_database_query = "CREATE DATABASE IF NOT EXISTS school"
    create_database(connection, create_database_query)

    # 选择school数据库
    connection.database = 'school'
    
    # 创建student表
    student_table_query = """
    CREATE TABLE IF NOT EXISTS student (
        id INT AUTO_INCREMENT PRIMARY KEY,
        name VARCHAR(100),
        age INT,
        class VARCHAR(50)
    );
    """
    create_table(connection, student_table_query)
    
    # 创建teacher表
    teacher_table_query = """
    CREATE TABLE IF NOT EXISTS teacher (
        id INT AUTO_INCREMENT PRIMARY KEY,
        name VARCHAR(100),

    create_table(connection, teacher_table_query)

    insert_data(connection, insert_student_query)
    
    # 插入数据到teacher表

                                                       ('钱老师', '物理', 8),
                                                       ('孙老师', '化学', 6);

    insert_data(connection, insert_teacher_query)
    
    # 查询并打印student表数据
    query_student_table = "SELECT * FROM student"
    query_data(connection, query_student_table)

    query_data(connection, query_teacher_table)

    connection.close()

if __name__ == '__main__':
    main()

请确保替换`your_password`为你自己的MySQL root用户的密码。
