Update mysql plz

[queerfm]

Hi I cant get this code to add the next number to imp when I run this script.

$result1 = mysql_query("UPDATE queerhuntradio_video_ads SET imp='+1' WHERE id='$row[id]' AND imp='$row[imp]'");

So if imp is 1 it makes it 2 if 2 it makes it 3

Please help

if you want to increase imp +1 you have to get the old value at first to add 1 on it like :

<?php

$sql = "select * from queerhuntradio_video_ads where id='$row[id]' ";
$res = @mysql_query ($sql);
$result = @mysql_fetch_array($res);

$old_value = $result[imp];
$new_value = $old_value +1 ;

$result1 = mysql_query("UPDATE queerhuntradio_video_ads SET imp='$new_value' WHERE id='$row[id]' AND imp='$row[imp]'");

Try it and let me know the result .

I believe it is possible in SQL to set something like tmp=tmp + 1

So:

update table where table.id = 1 SET value = value + 1
