complex mysql query need result sorted - php

Question

I have 3 mysql tables. I want to display leaderboard for team in descending order of d_money for particular day (like day 1, day 2, day 3.)
user(u_id(p),name)
team(t_id(p),u_id(f),t_name,t_money,days_money) and
history(t_id(f),day,d_money).
First i collected all t_id's in $tid_arr. Then for each t_id, i wrote query to get t_name and its days money.(for particular day. Here - day 1). It displays the result. But i want the result sorted (descending order of d_money). But i couldn't find the soultion.
$query = $con->prepare("SELECT t_id FROM team");
$query->execute();
$tid_arr = $query->fetchAll();
echo "<table border='1'>";
foreach($tid_arr as $tid)
{
$que = $con->prepare("SELECT d_money, t_name FROM team, history WHERE history.t_id=$tid['t_id'] AND team.t_id=history.t_id` AND history.day='1'");
$que->execute();
while($info = $que->fetch(PDO::FETCH_NUM))
{
echo "<tr>";
echo "<td>".$info[0]."</td>";
echo "<td>".$info[1]."</td>";
echo "</tr>";
}
}
echo "</table>";

Answer 1

If you want to order by d_money then t_id, you can use the following query. The 1st query is unnecessary and should be removed.
SELECT d_money, t_name FROM team a
LEFT JOIN history b ON a.t_id=b.t_id
WHERE history.day='1'
ORDER BY d_money DESC, t_id DESC
p.s. user table is not used ?

Answer 2

Add a Join and Order By clause to your SQL statement to be
echo "<table border='1'>";
$que = $con->prepare("SELECT T.t_id, H.d_money, T.t_name
FROM team T INNER JOIN history H ON T.t_id=H.t_id
WHERE H.day='1'
ORDER BY d_money DESC");
$que->execute();
while ($info = $que->fetch(PDO::FETCH_NUM)) {
echo "<tr>";
echo "<td>".$info[0]."</td>";
echo "<td>".$info[1]."</td>";
echo "</tr>";
}
echo "</table>";
