How do this query in laravel query builder?
select * from products p join
(
select product_id,sum(qty) total_sales
from orders where qty !=0 group by product_id
)
s on p.id = s.product_id
order by s.total_sales desc
There are different ways are there to do the same thing. But you can do with Raw Expressions is very similar to your above code.
if you want to use Eloquent, Do this provided the orders table has product_id that is a foreign key from products
DB::table('products')->join('orders','products.id','orders.product_id')->where('orders.qty','!=',0)->get()
The first part for sub-query for join
ed part. It is joined with toSql()
method inside the raw
statement.
$subQuery = DB::table('orders')
->where('qty', '!=', DB::raw(0))
->groupBy('product_id')
->select('product_id', DB::raw('sum(qty) as total_sales'));
return DB::table('products as p')
->join(DB::raw('(' . $subQuery->toSql() . ') s'), 'p.id', '=', 's.product_id')
->orderByDesc('s.total_sales')
->get();
It prints the following sql;
SELECT *
FROM `products` AS `p`
INNER JOIN (
SELECT `product_id`, SUM(qty) AS total_sales
FROM `orders`
WHERE `qty` != 0
GROUP BY `product_id`
) s ON `p`.`id` = `s`.`product_id`
ORDER BY `s`.`total_sales` DESC
