Laravel SQL Query difficult

Question

I can't "translate" the SQL Query below to Laravel, how I can make this?

SELECT SUM(transactions.amount) AS total, products.name 
FROM transactions, product_stock, product_catalog, products
WHERE transactions.id_product_stock = product_stock.id_prodct_stock
AND product_stock.id_product_catalog = product_catalog.id_product_catalog
AND product_catalog.id_product = products.id_produto
GROUP BY (products.name);

I tried this (returns error):

Transaction::join('product_stock', 'transactions.id_product_stock', '=', 'product.stock.id_product_stock')
    ->join('product_catalog', 'product_stock.id_product_catalog', '=', 'product_catalog.id_product_catalog')
    ->join('products', 'product_catalog.id_product', '=', 'products.id_product')
    ->groupBy('products.name')
    ->get([ DB::raw('SUM(transactions.amount) AS total'), DB::raw('products.name as name')]);

And this (returns empty):

DB::raw('select SUM(transactions.amount) AS total, products.name 
from transactions, product_stock, product_catalog, products
where transactions.id_product_stock = product_stock.id_prodct_stock
and product_stock.id_product_catalog = product_catalog.id_product_catalog
and product_catalog.id_product = products.id_produto
group by (products.name)');

Anyone can help me?

Answer 1

If you want to run the raw query (and for a complex query like this, I would stick with the raw SQL because I'm more comfortable with that), what you need to do is this:

$value = DB::select('select SUM(transactions.amount) AS total, products.name
    from transactions, product_stock, product_catalog, products
    where transactions.id_product_stock = product_stock.id_prodct_stock
    and product_stock.id_product_catalog = product_catalog.id_product_catalog
    and product_catalog.id_product = products.id_produto
    group by (products.name)'
);

Here's the documentation for use of the DB::select() method.

DB::raw() is used to mark part of a larger query expression as raw SQL. See http://laravel.com/docs/queries#raw-expressions for details & examples.

Answer 2

quick checking their documentation it looks like you want to run your entire query as a raw expression.
