php - 使用数组过滤记录 - Laravel

Question

我有一个集合，我想使用数组根据“days_since_last_wallet_transaction”过滤该集合。例如，我有一个数组 $day = array(2,4,6,8)。现在我想获取days_since_last_wallet_transaction在2,4,6,8中的记录。我认为我不能在 where 子句中使用“days_since_last_wallet_transaction”。这是我的查询:

Customer::select(
                'customers.id',
                'customers.wallet_amount',
                'customers.onesignal_id',
                'customers.phone_number',
                'customers.name',
                DB::raw('DATEDIFF(NOW(), max(wallet_transactions.created_at)) as days_since_last_wallet_transaction')
            )
            ->join('wallet_transactions', function ($join){
                $join->on('customers.id', '=', 'wallet_transactions.customer_id')
                ->where('wallet_transactions.amount', '>', 0);
            })
            ->groupBy('customers.id')
            ->where('customers.wallet_amount', '>', 0);

任何帮助都将非常感激。

Answer 1

考虑下面的数组:

$days = [2,4,6,8];

创建一个原始查询，如下所示(注意:您也可以在查询中写入此行)

$raw_query = '(DATEDIFF(NOW(), max(wallet_transactions.created_at))) IN  ('.implode(',',$days).')';

您的查询

Customer::select(
                'customers.id',
                'customers.wallet_amount',
                'customers.onesignal_id',
                'customers.phone_number',
                'customers.name',
                DB::raw('DATEDIFF(NOW(), max(wallet_transactions.created_at)) as days_since_last_wallet_transaction')
            )
            ->join('wallet_transactions', function ($join){
                $join->on('customers.id', '=', 'wallet_transactions.customer_id')
                ->where('wallet_transactions.amount', '>', 0);
            })
            ->where('customers.wallet_amount', '>', 0)
            ->havingRaw($raw_query)
            ->groupBy('customers.id');
