I’m quite inexperienced, that’s true, but I’ve grown a pair and I’ve come here to ask.. I’ve been stuck for a few hours on a solution that apparently would have everything to be simple, but I can’t see a way out.
I have two models, in one of them I have the basic product information (description, photo, etc) and in the other I have specific information of that package, as quantity in the package and price.
For example:
Product : Coca Cola 2 lts
Packings
UN:1 - 6.99
CX:12 - 83,88
I need to do a research that returns me the lowest price of packages registered by product.
The SQL would be this:
select DESCRICAO,
(select min(PRECO)
from PRODUTOEMBALAGEM
where PRODUTO.ID = PRODUTOEMBALAGEM.IDPRODUTO) as PRECO
from PRODUTO
inner join PRODUTOEMBALAGEM on PRODUTO.ID = PRODUTOEMBALAGEM.IDPRODUTO
where IDESTABELECIMENTO = 1
group by PRODUTO.ID, PRODUTO.DESCRICAO
Normally I could use an expression like
contexto.ProdutoEmbalagens.Min(c => c.Preco)
However, I am trying to bring product information as well:
var produtos =
(from prod in contexto.Produtos
join emb in contexto.ProdutoEmbalagems on prod.Id equals emb.IdProduto
where prod.IdEstabelecimento == idEstabelecimento
select new
{
prod.Id,
prod.Descricao,
emb.Embalagem,
emb.Quantidade,
emb.Preco
}).ToList();
Any idea? I know for sure the solution is simple, but I’ve already fried my head :(
Make a query to return the packages registered by product, and with the return of this you perform the expression
contexto.ProdutoEmbalagens.Min(c => c.Preco)
