Creating a table view for invoice - Northwind - sql

Question

I have a little problem with my last tasks. I am using an old Northwind database.
First, I had to create a query, that will give me all the important information for the invoice. My query looks like this:
SELECT b.OrderID,
b.CustomerID,
c.CompanyName,
c.Address,
c.City,
c.PostalCode,
c.CountryID as CustomersCountryID,
concat(d.FirstName, ' ', d.LastName) as Salesperson,
a.CompanyName as ShippingVia,
e.ProductID,
f.ProductName,
e.Quantity,
e.UnitPrice * e.Quantity * (1 - e.Discount) as ExtendedPrice
from Shippers a
inner join Orders b on a.ShipperID = b.ShipVia
inner join Customers c on c.CustomerID = b.CustomerID
inner join Employees d on d.EmployeeID = b.EmployeeID
inner join [Order Details] e on b.OrderID = e.OrderID
inner join Products f on f.ProductID = e.ProductID
order by b.OrderID
It works, it gives me all the orders made with informations. But now, I need to create a table view for an invoice of particular OrderId. When I write something like this:
CREATE VIEW FAKTURA AS
SELECT b.OrderID,
b.CustomerID,
c.CompanyName,
c.Address,
c.City,
c.PostalCode,
c.CountryID as CustomersCountryID,
concat(d.FirstName, ' ', d.LastName) as Salesperson,
a.CompanyName as ShippingVia,
e.ProductID,
f.ProductName,
e.Quantity,
e.UnitPrice * e.Quantity * (1 - e.Discount) as ExtendedPrice
from Shippers a
inner join Orders b on a.ShipperID = b.ShipVia
inner join Customers c on c.CustomerID = b.CustomerID
inner join Employees d on d.EmployeeID = b.EmployeeID
inner join [Order Details] e on b.OrderID = e.OrderID
inner join Products f on f.ProductID = e.ProductID
WHERE b.OrderID = 10248
I am just creating a separate view file for that particular OrderID. It doesn't look like a real life invoice at all.
It should resemble something like this:
I need to separate general data about invoice and customer from data about order itself, product ID, quantity etc.
Is it possible to create something similar in SQL Server Management Studio? How can I do it?

Answer 1

Your query already provides the header (customer info) and table body parts, so what you could do is (NOTE: this is NOT what I would do but, considering the need to have a very simple solution):
Phrase a query that would perform all the needed calculations for the trailing part based on the INVOICE number (this can be similar to what you already have except that it would SUM the amounts, calculate taxes and shipping cost),
Once you have that query ready, INNER JOIN it to the one you already have (using the invoice ID as a key); Note that you will have to add the additional fields to the top SELECTs list.
The result will be what you already have + the subtotal, tax, shipping and total in each and every record.
Again, this is NOT the most efficient and elegant solution, but matches your needs (simplicity and final result).
