python体验(06)Python处理mysql数据库

Python处理mysql数据库
1、检查用户环境：已经安装mysql-server，已经安装python-mysqldb 组件
        aptitude show mysql-server; aptitude show python-mysqldb

2、创建数据库，创建表，添加数据，修改mysql数据库的密码为Oracle11g

       use mysql;

        update user set password=password('Oracle11g') where user='root';

        flush privileges;

        ---------------------

        create database myfamily;

        use myfamily;

        create table people(id int, name varchar(30), age int, sex char(1));

        insert into people values(0,'Zihao Xu',5,'M');

        select * from people;exit;

3、编写pyMysql.py测试程序

phoenix@debian:~$ cat pyMysql.py

#!/usr/bin/python

#filename:pyMysql.py

#coding:utf-8



import MySQLdb

conn = MySQLdb.connect(host='127.0.0.1', db='myfamily',

        user='root', passwd='Oracle11g')

cur = conn.cursor()



r = cur.execute('insert into people values(6,\'Bill Gates\',58,\'M\')')

cur.execute('delete from people where age=58')

conn.commit()



r = cur.execute('select * from people')

r = cur.fetchall()

print r
