自己平时也就用到两个mysql函数:查询和更新,下面是自己常用的函数的封装,大家拷贝过去直接可以使用。
文件名:DBUtil.py
# -*- encoding:utf8 -*- ''' @author: crazyant.net @version: 2013-10-22 封装的mysql常用函数 ''' import MySQLdb class DB(): def __init__(self, DB_HOST, DB_PORT, DB_USER, DB_PWD, DB_NAME): self.DB_HOST = DB_HOST self.DB_PORT = DB_PORT self.DB_USER = DB_USER self.DB_PWD = DB_PWD self.DB_NAME = DB_NAME self.conn = self.getConnection() def getConnection(self): return MySQLdb.Connect( host=self.DB_HOST, #设置MYSQL地址 port=self.DB_PORT, #设置端口号 user=self.DB_USER, #设置用户名 passwd=self.DB_PWD, #设置密码 db=self.DB_NAME, #数据库名 charset='utf8' #设置编码 ) def query(self, sqlString): cursor=self.conn.cursor() cursor.execute(sqlString) returnData=cursor.fetchall() cursor.close() self.conn.close() return returnData def update(self, sqlString): cursor=self.conn.cursor() cursor.execute(sqlString) self.conn.commit() cursor.close() self.conn.close() if __name__=="__main__": db=DB('127.0.0.1',3306,'root','','wordpress') print db.query("show tables;")
使用方法为文件下面的main函数,使用query执行select语句并获取结果;或者使用update进行insert、delete等操作。
