------------------------------------------------------ 위에가 대략 a.php

<input type=hidden name=no value='<?=$no?>'>
<?
  include "setting.php";
  
  /* $query = "update limwb_v1_qna set
              ans='$edit_ans'
              where no='$no' "; */
              
    $query = "insert into limwb_v1_qna(ans, editregdate) values('$edit_ans',now()) where no='$no' ";
    mysql_query($query, $connect);
    mysql_close($connect);

  
?>

--------------------------------------------- 요게 update.php 입니다. no 값도 입력 받았는데 insert 가 왜 안되는지 도저히 몰르겠어요.. (setting.php 에서 db접속은 성공적으로 됩니다. select까지)
