Take info from one coloum and move to another

Posted on 16th Feb 2014 07:03 pm by admin

Hi all,

I have this:
Code: [Select]$array = "SELECT stock_id FROM stocks WHERE stock_id BETWEEN '1' and '5' ";
$res = mysql_query($array);
$count = 0;
while ($row = mysql_fetch_assoc($res)){
if (is_int($count / 10) || $count == 0){
$rand_low = rand(1,5);
$rand_high = rand(1,5);
}
$num = rand($rand_low,$rand_high);
$update = "UPDATE stocks SET t_val=$num WHERE stock_id='" . $row['stock_id'] ."'";
if (mysql_query($update)){
echo "Updated record(s)<br />n";
}
}
Which simply updates a coloum called t_val with a random value between 1 and 5. I have another coloum in the table called y_val. What I would like to do is take the value of t_val before it is updated with the new rand and save it to the y_val coloum. How would I do this?

Many thanks
