funbinod Posted May 7, 2014 Share Posted May 7, 2014 why these lines are not working? $sql3 = "SELECT *,sum(amt),sum(qty) FROM purchase WHERE sid=$sid AND pvn!=0 ORDER BY pvn DESC LIMIT 2";$result3 = mysqli_query($connect, $sql3) or die(mysqli_error($connect));$row3 = mysqli_fetch_array($result3);echo $row3['sum(qty)'] . "<br />";$sql4 = "SELECT *,sum(amt),sum(qty) FROM purchase WHERE sid=$sid AND pvn!=0 ORDER BY pvn DESC LIMIT 3";$result4 = mysqli_query($connect, $sql4) or die(mysqli_error($connect));$row4 = mysqli_fetch_array($result4);echo $row4['sum(qty)'] . "<br />"; they both SELECT result from the complete rows on 'purchase' table. please guide what is wrong in it! Link to comment Share on other sites More sharing options...
Muhammad92 Posted May 7, 2014 Share Posted May 7, 2014 if you can use sum syntax your can use Group and declare field of table don't use select * .Example : Select sid,pvn ,item_name,sum(amt) as amt ,sum(qty) as Qty From purchase Where sid=$sid AND pvn!=0 Group by sid,item_name,pvn ORDER BY pvn DESC LIMIT 3"; sorry my spelling bad.

funbinod Posted May 7, 2014 Author Share Posted May 7, 2014 thanks for the reply. its ok for the spelling! but the problem is still the same. its not retrieving sum from last 3 rows. its summing from complete rows.... i wish to add qty from the declared LIMIT...
