win7上python2.7連接mysql數據庫

一：安裝mysql

下載地址：http://dev.mysql.com/downloads/installer/

*mysql的安裝以及基本sql操作提前預習一下

二：安裝MySQL-python驅動

下載地址：http://dev.mysql.com/downloads/connector/python/

根據自己操作系統和python版本選擇相對應的驅動

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

三：演示如何連接到MySQL服務器的test數據庫

>>> import mysql.connector
>>> conn=mysql.connector.connect(
	user='root',
	password='',
	database='test') #連接數據庫
>>> cursor=conn.cursor()
>>> cursor.execute('select * from student where 1=1') #表查詢
>>> 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']) #插入數據
>>> 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')]
