python操作mysql——mysql.connector

Posted 2021-02-01 浅唱年华1920

先安装 pip python 的包管理工具

 

然后 

sudo pip install mysql-connector-python

 

连接数据库

#!/usr/bin/python
# -*- coding: UTF-8 -*-
import mysql.connector

db = mysql.connector.connect(
    host = ‘127.0.0.1‘,
    port = 3306,
    user = ‘root‘,
    passwd = ‘gou110422‘,
    database = ‘test‘,
    charset = ‘utf8‘
)
cursor = db.cursor()

sql_query = ‘select name,money from user;‘
#执行sql 语句
cursor.execute(sql_query)
print cursor.rowcount
rs = cursor.fetchall()
#cursor.rowcount 表中受影响数据个数
#fetchall() 获取所有数据
#fetchone()  获取一条数据
#fetchmany(3) 获取 3个数据
print rs
for item in rs:
    print ‘name: %s  money: %s‘ % item
print ‘成功‘
#cursor.close() #关闭游标
db.close()
