pymysql事务保存一个insert查询，但忽略两个update查询而不会引发错误

import pymysql

# 创建数据库连接
conn = pymysql.connect(host='localhost', user='root', password='password', database='mydb')

try:
    # 开启事务
    conn.begin()

    # 创建游标对象
    cursor = conn.cursor()

    # 执行insert查询
    insert_query = "INSERT INTO mytable (column1, column2) VALUES ('value1', 'value2')"
    cursor.execute(insert_query)

    # 忽略两个update查询

    # 提交事务
    conn.commit()

    # 关闭游标
    cursor.close()

except Exception as e:
    # 发生错误时回滚事务
    conn.rollback()
    print("Error:", e)

finally:
    # 关闭数据库连接
    conn.close()
