MySQL-mysql与python的交互

首先需要在pycharm中安装pymysql模块

步骤:

1.引入pymysql

import pymysql

2.配置并获得连接:

conn=pymysql.connect(kwargs){
host='localhost',
port=3306,
user='xxx',
database='xxx'
charset='utf8'
}

3.获得查询游标

cursor = conn.cursor()

4.执行SQL语句:

affected = ursor.execute(sql)
例:
affected = ursor.execute('insert student(name,sex)values('xiaoming',1);')

5.从游标中获得结果:

cursor.fetchall()

6.提交结果

conn.commit()

7.断开连接

conn.close()
