本文实例讲述了Python实现一个简单的MySQL类。分享给大家供大家参考。

具体实现方法如下：

复制代码 代码如下:#!/usr/bin/env python

# -*- coding:utf-8 -*-

# Created on 2011-2-19

# @author: xiaoxiao

import MySQLdb

import sys

__all__ = ['MySQL']

class MySQL(object):

'''

MySQL

'''

conn = ''

cursor = ''

def __init__(self,host='localhost',user='root',passwd='root',db='mysql',charset='utf8'):

"""MySQL Database initialization """

try:

self.conn = MySQLdb.connect(host,user,passwd,db)

except MySQLdb.Error,e:

errormsg = 'Cannot connect to servernERROR (%s): %s' %(e.args[0],e.args[1])

print errormsg

sys.exit()

self.cursor = self.conn.cursor()

def query(self,sql):

""" Execute SQL statement """

return self.cursor.execute(sql)

def show(self):

""" Return the results after executing SQL statement """

return self.cursor.fetchall()

def __del__(self):

""" Terminate the connection """

self.conn.close()

self.cursor.close()

#test

if __name__ == '__main__':

mysql = MySQL(host=localhost,passwd='test',db='mysql')

mysql.query('select * from users')

result = mysql.show()

print len(result)

print result[1]

希望本文所述对大家的Python程序设计有所帮助。
