Laravel adding WHERE to DB::raw and Joins - mysql

Question

Here is my code:
return ExportInvoice::join('sold_products', 'sold_products.export_invoice_id', '=', 'export_invoices.id')
->join('products', 'sold_products.product_id', '=', 'products.id')
->select(
'sold_products.product_id',
'products.name',
DB::raw('
round(round(sum(round(sold_products.sold_price * sold_products.quantity * (1 - sold_products.discount / 100), 2))
* (1 - export_invoices.discount / 100), 2) * (1 + IF(export_invoices.tax, 14, 0) / 100), 2)
as total
')
)
->groupBy('sold_products.product_id', 'products.name', 'export_invoices.discount', 'export_invoices.tax')
->orderBy('total', 'DESC')
->limit(100)
->get();
What I am trying to do:
I am trying to add whereNotNull('export_invoices.deleted_at') and whereNotNull('sold_products.deleted_at') because I am using Laravel soft delete and the above query return all data even those who are soft-deleted.

If you are not able to do just ->whereNull('sold_products.deleted_at') and ->whereNull('export_invoices.deleted_at') then try to add this after select statement.
$columns = ['sold_products.deleted_at', 'export_invoices.deleted_at']
->where(function($q) use ($columns){
foreach($columns as $column){
$q->whereNull($columns);
}
})
So it would be:
$columns = ['sold_products.deleted_at', 'export_invoices.deleted_at']
return ExportInvoice::join('sold_products', 'sold_products.export_invoice_id', '=', 'export_invoices.id')
->join('products', 'sold_products.product_id', '=', 'products.id')
->select(
'sold_products.product_id',
'products.name',
DB::raw('
round(round(sum(round(sold_products.sold_price * sold_products.quantity * (1 - sold_products.discount / 100), 2))
* (1 - export_invoices.discount / 100), 2) * (1 + IF(export_invoices.tax, 14, 0) / 100), 2)
as total
')
)->where(function($q) use ($columns){
foreach($columns as $column){
$q->whereNull($columns);
}
})->groupBy('sold_products.product_id', 'products.name', 'export_invoices.discount', 'export_invoices.tax')
->orderBy('total', 'DESC')
->limit(100)
->get();
I hope it helps!
