pandas连接mysql数据库

pandas连接mysql数据库

1.安装依赖 "UserWarning: pandas only supports SQLAlchemy connectable (engine/connection) or database string URI or sqlite3 DBAPI2 connection. Other # DBAPI2 objects are not tested. Please consider using SQLAlchemy."

conda install sqlalchemy pymysql

2.导入类库

from sqlalchemy import create_engine

import pandas as pd

3.创建数据库连接字符串

user = 'root'

password = '123456'

host = '127.0.0.1'

port = '3306'

database = 'lrcore_cloud_xxx'

db_url = f'mysql+pymysql://{user}:{password}@{host}:{port}/{database}'

4.创建 SQLAlchemy 引擎

engine = create_engine(db_url)

5.使用 Pandas 读取数据

df = pd.read_sql_table('user', engine)

print(df)

'''

输出结果

id name

0 1 jack

1 2 boom

2 3 lucy

3 4 jack
