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。
