从 Jupyter 笔记本连接到 MySQL 数据库

Question

I am using Jupyter Notebooks to learn Python. I would like to connect to a MySQL db hosted locally hosted through MAMP. How would I approach this?

Answer 1

import os
import pymysql
import pandas as pd

host = os.getenv('MYSQL_HOST')
port = os.getenv('MYSQL_PORT')
user = os.getenv('MYSQL_USER')
password = os.getenv('MYSQL_PASSWORD')
database = os.getenv('MYSQL_DATABASE')

conn = pymysql.connect(
    host=host,
    port=int(3306),
    user="root",
    passwd=password,
    db="[YOUR_DB_NAME]",
    charset='utf8mb4')

df = pd.read_sql_query("SELECT * FROM YOUR_TABLE",
    conn)
df.tail(10)

Answer 2

Assuming you have MySQL installed (instructionshere for macOS using HomeBrew), you need to:

• Install pip3 install ipython-sql
• pip3 install mysqlclient

now you should be able to run these cells and get pretty-printed HTML output:

# %%
%load_ext sql

# %%
%sql mysql+mysqldb://<user>:<password>@localhost/<dataBase>

# %%
%%sql

SELECT *
FROM <table>;

Answer 3

import pymysql

import pandas as a

conn=pymysql.connect(host='localhost',port=int(3306),user='root',passwd='YOUR_PASSWORD',db='YOUR_DATABASENAME')

df=a.read_sql_query("SELECT * FROM 'YOUR_TABLENAME' ",conn)

print(df)

Answer 4

Yes, you can. You can use the MySQL Connector library. Simply install it using pip, and then you can use it to interact with your database. See the sample code below:

import mysql.connector

db = mysql.connector.connect(
   host="localhost",
   user="mamp",
   passwd=""
)

print(db)
