MySQL-基于一个字段的表中的列总和

Question

I have a table in my database that's structured as such:

Week  Team   Player     Plants  Score  Ball Kills
1     Team1  Player1.1   1        1      1   
1     Team1  Player1.2   2        1      0   
1     Team2  Player2.1   0        4      3   
1     Team2  Player2.2   3        1      5   
2     Team1  Player1.1   2        7     11  
2     Team1  Player1.2   2        2      0   
2     Team2  Player2.1   0        0      1   
2     Team2  Player2.2   2        1      1   

I'm trying to output a table where I sum all the fields of the table based on a Player (Eg sum all the values for Player1.1 to get the total for each column)

So for instance:

/ Team / / Player / / Plants / / Score / / Ball Kills /.....
/ Team1 / / Player1.1 / / 3 / / 8 / / 12 /.....
/ Team1 / / Player1.2 / / 4 / / 3 / / 0 /.....
/ Team2 / / Player2.1 / / 0 / / 4 / / 4 /.....
/ Team2 / / Player2.2 / / 5 / / 2 / / 6 /.....

This is the code I have so far. Obviously it just outputs the entire table.

$sql = "SELECT * FROM Table1";
$Data = mysql_query ($sql,$con);

echo '<table class="db-table" cellpadding="0" cellspacing="0">

<tr>
<th>Team</th>
<th>Player</th>
<th>Plants</th>
<th>Ball Kills</th>
<th>First Touch</th>
<th>Fast Break</th>
<th>Runner Score</th>
<th>Tank Score</th>
<th>Defender Score</th>

</tr>';
while ($results = mysql_fetch_array ($Data)){
echo "<tr>";
echo "<td>" . $results['Team'] . "</td>";
echo "<td>" . $results['Player'] . "</td>";
echo "<td>" . $results['Plants'] . "</td>";
echo "<td>" . $results['Ball Kills'] . "</td>";
echo "<td>" . $results['First Touch'] . "</td>";
echo "<td>" . $results['Fast Break'] . "</td>";
echo "<td>" . $results ['Runner Score'] . "</td>";
echo "<td>" . $results['Tank Score'] . "</td>";
echo "<td>" . $results['Defender Score'] . "</td>";
echo "</tr>";
}

echo "</table>";

I've looked at many examples of my problem, however it doesn't do what I want when I put the code in, and I can't figure out why. I am new to php, so any help would be appreciated.

Answer 1

You can use one query using group by

select
t.Team,
t.Player,
sum(t.Plants) as Plants,
sum(t.Score) as Score,
sum(t.`Ball Kills`) as `Ball Kills`
from table1 t1
group by 
t.Team,
t.Player

Answer 2

try this:

SELECT
t.Team,t.Player,sum(t.'Ball Kills') as 'Ball Kills',sum(t.Plants) as plants,
sum(t.Score) as Score
FROM Table1 t
GROUP BY Team,player
ORDER BY 'Ball Kills',plants
