結合クエリのエラー不明なインデックス

Question

私はこのクエリの結果に間違っています。

total_fund .name 

のように記述する必要があります：

total_fund.name 

、あなたはおそらくとにかくそれはあなたのクエリをこのように書く方が良いでしょう、ASエイリアスを必要とするクエリにタイプミスがあります

<?php 

include 'dbconfig.php'; 
$sql = 'SELECT SUM(total_fund.total_funds), total_fund .name from total_fund join project 
     WHERE total_fund.funds_id = project.project_id AND project_id=1200 GROUP BY project.project_id'; 
$retval = mysqli_query($dbconfig, $sql); 

while ($data = mysqli_fetch_array($retval)) { 

    echo $data['total_funds'] . '</br>'; 
    echo $data['name']; 
} 
?> 

Answer 1

：

select 
    total_fund.name 
    SUM(total_fund.total_funds) as total_funds 
from 
    total_fund join project on total_fund.funds_id = project.project_id 
where 
    project_id=1200 
group by 
    total_fund.name 

Answer 2

ここでは完全なクエリです

<?php 

include 'dbconfig.php'; 
$sql = 'SELECT SUM(total_fund.total_funds)AS total, total_fund .name, project.Amount_to_be_raised from total_fund join project 
     where total_fund.funds_id = project.project_id AND project_id=1200'; 
$retval = mysqli_query($dbconfig, $sql); 

while ($data = mysqli_fetch_array($retval)) { 

    echo $data['total'] . '</br>'; 
    echo $data['name']; 
} 
?>
