can anyone please tell me what's the difference between stock_move & stock_picking? If stock_move trace all movements of products from a location to another why using stock_picking?
Stock_picking is simply a collection of stock_move. Normally, when a stock_picking is created, it includes many items in it and each line in the picking is a stock move. A stock_picking is done only when all stock_moves in that picking are done. Same concept as sale_order and sale_order_line

So my basic goal is to create a database for a shopsystem, which is my task to do for my IT course. I tried to create a UPDATE-Query, that collects all the Sale Positions ("tblPosition.PositionAnzahl") ordered with a SELECT-Query and groups it by the products ordered, to have an overview about how often each product has been sold.
I want to do this to keep track of how many items are still left in the inventory.
The Query was supposed to update 1 field ("tblArtikel.ArtikelVerkauft") in my table "tblArtikel", in which all my articles and their information is stored.
However, i just found out that you cannot run UPDATE-Queries, that use SELECT-Query data, as i get a error, that says "Operation must use an updateable query".
This is the code i used for the query:
UPDATE tblArtikel as a JOIN
(SELECT p.PositionArtikelID, Sum(p.PositionAnzahl) AS SumOfPositionAnzahl
FROM tblPositionen as p
GROUP BY p.PositionArtikelID
) p
ON a.ArtikelID = p.PositionArtikelID
SET ArtikelVerkauft = p.SumOfPositionAnzahl;
Is there another way to keep track of all the Items left in my inventory, apart from doing what i did?
Here are screenshots of the 2 tables (the depending fields are circled red):
tblPositionen with field PositionAnzahl
tblArtikel with field ArtikelVerkauft
I have not worked with SQL before and only learned about it during 45 min, so ther emight be an easy way for this, but i would still appreciate every answer from you guys.
I would like to understand differences between:
stock_move table
and
stock_picking table
what are they both used for? which are the differences between both?
A stock picking represents an operation, let's say, you taking some goods from location A to location B. You move 10 item A and 10 item B.
A stock move represents the action of moving 10 items A from location A to location B. Another stock move is the action of moving 10 item B from location A to location B.
A stock picking may contain several stock moves.
The stock picking is the moving operation. Stock moves represent individual stock movement.
I would say that move is the move in the accounting way, which means that you move a product from stock to customer. Whereas picking is the physical move from stock to a package.
Every article I need to solve my problem seems to be in C# and I need a solution in VB.NET.
I'm using EF 6.0 with Database First model. Let me use the classic Customer product scenario to demonstrate my situation. In my database I have three tables Customer, Product and CustomerProduct. See this example in this link as mine is exactly the same.
After I generate my model from the database, my entity model diagram shows that the CustomerProduct has disappeared as expected and the the model shows a many to many relationship between Customer and Product also as expected with navigational properties of Products in Customer and Customers in Product.
All I want to do is find the product related to a customer pull out some data from both tables namely CustName and ProductName.
The SQL I would use is:
SELECT c.CustName, p.ProductName FROM Customer c
INNER JOIN CustomerProduct cp on c.CustomerId = cp.CustomerId
INNER JOIN Product p on cp.ProductId = p.ProductId
WHERE c.CustomerId=101
I don't know how to use the Addresses navigational property to access the Address data in one query.
You include them and then access them via the property in the Entity class.
Dim query = model.User.Include("Address").Include("UserAddressLink").Where(Function(o) o.UserId = 101).FirstOrDefault
If Not query Is Nothing Then
Dim houseNumber = query.Address.HouseNo 'uses the navigation property
End If
Thanks to InteXX I managed to work it out. This is my whole solution
Using db as new CustProdEntities
Dim query = db.Customers.Include(Function(U) U.Products).ToList
txtCustomer.Text = query.First.CustName
txtProduct.Text query.First.Products.First.ProdName
End Using
The bit I was stuck on was having to filter twice to the Product data. I'm not sure if there's an easier way to do this but it works for now.

I have the following tables and relationships.
When loading the NEW_CHALLAN form, I am trying to fill a Grid View with Product Details - Product Name, Stage, Pro, Katta, Packing, Rate, Quantity.
I am facing a problem (getting 0 records as result set) when using JOIN for this operation as there are no matching records(ChallanId, ProductId, OrderId) in the ChallanProductDetails table yet (when loading the form)
Any suggestions on how to solve this problem ?
If you are trying to load product details even tough there are no order/challan details then you can try something like below,
select a.productname,a.productprice,c.stage,c.pro...etc from product a
left outer join challanproductdetails b
on a.productid= b.productid
brother I am not sure what exactly your asking for is it to retrieve data from a view or two tables if you are retrieving only then why don't you create a view of two tables and just call it straight to the grid that will be easy.
Please correct me if I am wrong.
Update take 2
here is the two queries i'm working with (paging is omitted in both queries)
i'd like to get the following query
SELECT *
FROM product
LEFT OUTER JOIN
(
SELECT *
FROM Cart
LEFT OUTER JOIN
cartproducts
ON Cart.Id = cartproducts.Cart_id
WHERE Cart.username = 'user'
)
AS CartFiltered
ON product.Id = CartFiltered.product_id
but i always seem to get
SELECT *
FROM product
LEFT OUTER JOIN
cartproducts
ON product.Id = cartproducts.Product_id
LEFT OUTER JOIN
Cart
ON
cartproducts.cart_id = cart.id
WHERE Cart.username = 'user'
How can i manage to create the first type of query?
I hope my question is clearer :) lack of clarity is sometimes a great enemy of mine :p
Update:
FWIW, i still haven't found the answer, and am currently loading the paged product data and the whole cart to display the correct object.
Crude solution but it works and it beats the combinatorials i've been through trying to make the Criteria API recognize me as its master. I would be very interested if somebody could happen to point me in the right direction though ;)
Hello,
i'm having a hard time writing the following query in the Criteria API, and i don't really see how to do it: i hope some people can help.
On the database, i have products. Theses products can be in many carts (one cart per user), and each cart can contain many products, so we have a manytomany relationship.
I would like to display a list of every product, along with a small icon next to it to inform the user that this particular product is already in the cart. What i did is i asked NHibernate for my products, and to do a left outer join on carts filtered by the cart's owner.
Dim critPage As ICriteria = Session.CreateCriteria(GetType(Product)) _
.SetFirstResult(pageNumber * itemsPerPage).SetMaxResults(itemsPerPage) _
.CreateCriteria("Carts", "c", SqlCommand.JoinType.LeftOuterJoin) _
.SetProjection(plist) _
.SetResultTransformer(New TypedResultTransformer(Of ProductWithCartInfo)) _
.Add(Expression.Eq("c.User", username))
the projection list is here to reduce the number of columns to what's interesting for the ProductWithCartInfo class. It contains only property projections.
The problem is that with this query, the cart filtering is applied to the whole result set and i don't see every product with its presence in the user's cart, but rather every product in the user's cart.
Is it possible to do a left outer join on a subquery with the Criteria API in Nhibernate? For information, i would like to keep it in the Criteria API if possible.
Thanks
I'm not sure I entirly follow your issue but it sounds very similar to an issue I had. I seems that when you have the nested (sub) criteira with NHibernate you loose some of the control. I was able to get around my issue but aliasing my tables instead of using the nested criteira.
Possibly try...
criteria.CreateAlias("Cart", "Cart", JoinType.LeftOuterJoin);
and then your filter on the cart will have to be an OR condition
ICriterion cartCriterion = Restrictions.Eq("Cart.User", username);
customerCriterion = Restrictions.Or(customerCriterion, Restrictions.IsNull("Cart.User"));
criteria.Add(customerCriterion);
Let me know if that helps you out... if not... maybe post the SQL that your criteria above is generating and where it needs to change.
Good Luck
