sql语法错误!不知道原因?

语法错误，改正一下就好
把下面的复制个吧
以后多注意$sql = "INSERT INTO com_comment(`subject_id`,`admin_pid`,`author_pid`,`author`,`content`,`submit_date`,`status`,`ip`,`gender`,`is_support`,`username`,`floor_num`)VALUES(".$v['pid'].",".$v['pid'].",".$kf_id.",'".$nikename."','".$arr1[rand(0,count($arr1)-1)]."','".date("Y-m-d h:i:s")."',0,".sprintf("%u", ip2long(server::getIP())).",2,".Request::getPara('support').",'".$author."',".$floor.")";
