Php 为什么查询DEO在有行的情况下不获取结果？

我正试图从两个表中取出记录

1-代币 2-交易

在这两个表中都有相同的列

user\u id

和

tokens

表中有

transaction\u id

。我正在尝试获取与

令牌

相关的所有事务。我在试着跟随

$EarnedData = Token::whereIn('user_id', $descendants)
    ->whereHas('transaction', function($q){
            $q->where('custom', '!=', 'BB')->orWhereNull('custom');
    })->sum('amount');

    select sum(`amount`) as aggregate from `tokens` 
    where 
    `user_id` in (15, 49, 58,117, 119, 120, 130, 13) 
    and exists 
    (select * from `transactions` where `tokens`.`transaction_id` = `transactions`.`id`
    and (`custom` != 'BONUS' or `custom` is null))

调试之后，我从上面的脚本中得到了原始查询，下面是

$EarnedData = Token::whereIn('user_id', $descendants)
    ->whereHas('transaction', function($q){
            $q->where('custom', '!=', 'BB')->orWhereNull('custom');
    })->sum('amount');

    select sum(`amount`) as aggregate from `tokens` 
    where 
    `user_id` in (15, 49, 58,117, 119, 120, 130, 13) 
    and exists 
    (select * from `transactions` where `tokens`.`transaction_id` = `transactions`.`id`
    and (`custom` != 'BONUS' or `custom` is null))

当我执行查询时，我得到了

NULL

，有人能告诉我为什么查询没有得到记录吗。我很感激。

因为你永远不会

->-get（）结果！
$earnedData
变量现在包含已解析的查询，因为您从未执行过它

$earnedData = Token::whereIn('user_id', $descendants)
    ->whereHas('transaction', function($q) {
        $q->where('custom', '!=', 'BB')->orWhereNull('custom');
    })->sum('amount')
    ->get();
