Python连接mysql数据库 查询 importpymysqlif__name__ =='__main__':# 创建连接对象con = pymysql.connect(host="localhost", port=3306, user="xxxx", password="xxxx", database="db1", charset="utf8")# 获取游标cur = con.cursor()# sql
一、python连接mysql数据库 安装第三方依赖PyMySQL, 终端执行如下命令: pip install PyMySQL PyMySQL使用 importpymysql config = {'host':'127.0.0.1','port':3306,'user':'root','password':'root','database':'mysql', }# 获取连接connection = pymysql.connect(**config)# 获取游标cursor = connection...
Database version : 5.0.45创建数据库表如果数据库连接存在我们可以使用execute()方法来为数据库创建表,如下所示创建表EMPLOYEE:#!/usr/bin/python # -*- coding: UTF-8 -*- import MySQLdb # 打开数据库连接 db = MySQLdb.connect("localhost", "testuser", "test123", "TESTDB", charset='utf8' ) ...
该代码将导入 mysql.connector 库,并使用connect()函数连接到灵活服务器,使用配置集合中的参数。 该代码对连接使用游标,并通过cursor.execute()方法对 MySQL 数据库执行 SQL 查询。 Windows 命令提示符 import mysql.connector from mysql.connector import errorcode # Obtain connection string information from the po...

二、Python操作MySQL 1.安装 $ pip3 install PyMySQL 2.数据库连接 代码语言:javascript 代码运行次数:0 运行 AI代码解释 importpymysql # 打开数据库连接 db=pymysql.connect(host='127.0.0.1',user='user',password='123456',database='demo',port=3306,charset='utf8')# 使用cursor()方法创建一个游标对...
This manual describes how to install and configure MySQL Connector/Python, a self-contained Python driver for communicating with MySQL servers, and how to use it to develop database applications. The latest MySQL Connector/Python version is recommended for use with MySQL Server version 8.0 and high...
