        db = MySQLdb.connect("localhost", "root", "root", "yingshi", charset='utf8' )
        cursor = db.cursor()
        sql_query = "select * from source where url =\'%s\' and  domain =\'%s\' and source = \'%s\'" % (url,domain,source)
        count=cursor.execute(sql_query)
        count=int(count)

        if count == 0:
            #更新
            #result = cursor.fetchone()
            #sql_update="update source set url=\'%s\' ,  domain =\'%s\' , source = \'%s\'" % (url,domain,source) %"where id = %s " % result[0]
            #增加
            sql = "INSERT INTO SOURCE(URL, DOMAIN, SOURCE) VALUES (\'%s\', \'%s\', \'%s\')" % (url,domain,source)
            cursor.execute(sql)
