How to add subquery in laravel query builder - laravel

Question

I'm trying to convert my sql query to Laravel Query
From this
SELECT products.name,
(SELECT SUM(orders.date BETWEEN from_date AND to_date)
FROM orders WHERE orders.product_id = products.id ) as order_counts
FROM products;
Then I tried converting to laravel query builder but it results to an error:
Product::select('name',
DB::raw("SUM(orders.date
BETWEEN $request->from_date AND $request->to_date) AS total_orders
FROM orders WHERE orders.product_id = products.id"))
->get();
The error is syntax error on the $request->from_date inside db::raw.

Answer 1

You can use the withCount method: Documentation
Product::select('name')->withCount([
'orders' => function (Builder $query) using ($from_date, $to_date) {
$query->whereBetween('date', [$from_date, $to_date]);
}
]);
I saw you have edited your issue, and describe your error. When using variables in string you should put them in braces.
Product::select('name',
DB::raw(
"SUM(orders.date BETWEEN {$request->from_date} AND {$request->to_date}) AS total_orders FROM orders WHERE orders.product_id = products.id"
)
)->get();
