python解决SQLAlchemy+MySQL插入数据时报警告Warning: (1366, "Incorrect string value: ‘\xD6\…’ for column …

1.工具环境

Pycharm2018.3
python3.7
Anaconda3.7
mysql5.7
sqlalchemy1.2.15

2.问题描述

在插入数据的时候抛出以下异常：
Warning: (1366, “Incorrect string value: ‘\xD6\xD0\xB9\xFA\xB1\xEA…’ for column ‘VARIABLE_VALUE’ at row 484”)
result = self._query(query)

3.相关代码

from sqlalchemy import create_engine
from sqlalchemy.orm import sessionmaker
from sqlalchemy.ext.declarative import declarative_base
from sqlalchemy import Column, Integer, String

Base = declarative_base()

class User(Base):
    __tablename__ = 'user'
    id = Column(Integer, primary_key=True)
    name = Column(String(255))
    sex = Column(String(8))

if __name__ == "__main__":
engine = create_engine("mysql+pymysql://root:password@localhost/my_db")
Session = sessionmaker(bind=engine)
user= User(name="测试", sex="男")
session = Session()
session.add(user)
session.commit()
session.close()
print("插入成功")

执行后抛出警告

驱动暂时使用的是pymysql，问题就在这里，各种网上搜索解决方案，基本上都是说字符集的不统一导致的，解决方法都是修改数据库和pycharm字符集，保持统一，但都没有效果，依然抛出异常

4.解决方法

1.安装mysql-connector-python驱动
conda install mysql-connector-python
2.修改代码

engine = create_engine("mysql+pymysql://root:password@localhost/my_db")

改为：

engine = create_engine("mysql+mysqlconnector://root:password@localhost/my_db")

执行后插入成功，一切正常
