밑에 sql문 보시면 그냥 아이디로 찾아서 쭉 나오게 되어있는데
이걸 해당 아이디에 po_rel_table이 b10인 것만 골라서 리스트를 뽑고싶습니다...
po_rel_table은 물론 point_table 안에 있는 테이블입니다...
sql문을 어떻게 수정해야하나요?

<?
include_once("./_common.php");
include_once("../_head.php");

if (!$member[mb_id])
    alert("회원만 조회하실 수 있습니다.");

$g4[title] = $member[mb_nick] . "님의 포인트 내역";
include_once("$g4[path]/head.sub.php");

$list = array();

$sql_common = " from $g4[point_table] where mb_id = '$member[mb_id]' ";
$sql_order = " order by po_id desc ";

$sql = " select count(*) as cnt $sql_common ";
$row = sql_fetch($sql);
$total_count = $row[cnt];

$rows = $config[cf_page_rows];
$total_page  = ceil($total_count / $rows);  // 전체 페이지 계산
if (!$page) { $page = 1; } // 페이지가 없으면 첫 페이지 (1 페이지)
$from_record = ($page - 1) * $rows; // 시작 열을 구함

$width = "971";
