mysql python 交互

 

一、安装

    sudo apt-get install pymysql

    sudo pip3 install pymysql

二、python 与mysql 连接代码

from pymysql import *
try:
    conn=Connection(host="localhost",port=3306,user="root",passwd="mysql",db='python3',charset="utf8")
    cursor1=conn.cursor()
    sql="insert into students(name) values('郭小二')"
    #sql="update students set name= '王小二' where id = 9"
    #sql="delete from students shere id=9"
    cursor1.execute(sql)
    conn.commit()
    cursor1.close()
    conn.close()
except Exception :
    print("错误")

三、sql语句参数化

防止sql注入
