I have a database full of teams and dates when the teams start out. For this particular tournament teams enter at 4 different stages (dates)...

What is quicker?

1. Do four different mysql queries which would return only the teams during selected date intervals?
2. Do one query which would return all teams and then use php to separate out what is to be returned when?

Thanks..

how about running a test?

<?php
function timer()
{
    list($usec, $sec) = explode(" ", microtime());
    return ((float)$usec + (float)$sec);
}

$t1 = timer();
// do method 1

$t2 = timer();
// do method 2

$t3 = timer();

$total1 = $t2-$t1;
$total2 = $t3-$t2;
echo "Method 1 :  $total1 <br />";
echo "Method 2 :  $total2 <br />";
?>

edit: I stoled this code snippet from barand's poll. not that i couldn't have done it myself, but i'm lazy such and all.  just giving credit where credit is due ;D

Please, take the time and do some research and find out how much it would have cost you to get your help from a decent paid-for source. A "roll-of-the-dice" freelancer will charge you $5-$15/hr. A decent entry level freelancer will charge you around $15-30/hr. A professional will charge you anywhere from $50-$100/hr. An agency will charge anywhere from $100-$250/hr. Think about all this when soliciting for help here. Think about how much money you are making from the work you are asking for help on. No, we do not expect you to pay for the help given here, but donating a few bucks is a fraction of the cost of what you would have paid, shows your appreciation, helps motivate people to keep offering help without the pricetag, and helps make this a higher quality free-help community :)
