from wiz_prdprice as a, exchange as b
WHERE 1=1
AND b.ex_regdate = '".$row['ex_DATE']."'
AND a.it_id='".$_GET['prdcode']."'
AND a.prc_price31 > 0
GROUP BY a.it_id


위에 쿼리문에서 보시듯 현재는 prc_price31에 대하여 SUM3만 뽑고 있는데요 ?

이걸 각각 price1에 대하여는 SUM1, price2는 SUM2, price3은 SUM3으로 뽑을 수 있을까요 ?
 다음글 메일 관련!! (5)
 이전글 mysql query 문에 대한 질문요 ? (6)

이렇게 해서 뽑긴 뽑았는데...

이게 맞을런지 모르겠네요 ㅠ.ㅜ
