win7上python2.7连接mysql数据库

一：安装mysql

下载地址：http://dev.mysql.com/downloads/installer/

*mysql的安装以及基本sql操作提前预习一下

二：安装MySQL-python驱动

下载地址：http://dev.mysql.com/downloads/connector/python/

根据自己操作系统和python版本选择相对应的驱动

例如(mysql-connector-python-2.1.3-py2.7-winx64.msi)

三：演示如何连接到MySQL服务器的test数据库

>>> import mysql.connector
>>> conn=mysql.connector.connect(
	user='root',
	password='',
	database='test') #连接数据库
>>> cursor=conn.cursor()
>>> cursor.execute('select * from student where 1=1') #表查询
>>> values=cursor.fetchall()
>>> values
[]
>>> cursor.close()
True
>>> conn.close()

---

>>> import mysql.connector
>>> conn = mysql.connector.connect(user='root', password='', database='test')
>>> cursor = conn.cursor()
>>> cursor.execute('create table user (id varchar(20) primary key, name varchar(20))')  #建表
>>> cursor.execute('insert into user (id, name) values (%s, %s)', ['1', 'Michael']) #插入数据
>>> cursor.rowcount
1
>>> conn.commit()
>>> cursor.close()
True

---

>>> cursor = conn.cursor()
>>> cursor.execute('select * from user where id = %s', ('1',))
>>> values = cursor.fetchall()
>>> values
[(u'1', u'Michael')]
>>> cursor.execute('update user set name=%s where id=%s',('zf','1')) #更新
>>> cursor.execute('select * from user ')
>>> values = cursor.fetchall()
>>> values
[(u'1', u'zf')]
