Python实现一个简单的MySQL类


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

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 server\nERROR (%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。
