I wanna ask if I can put just one table for both prices an cities.
In the beginning I created just table Product, but I have two different prices by cities(each city has a particular price).
After that I put two tables one for cities and one prices. but I think I don't need table cities, I'm asking if I can create one table prices with field city.
my data base NOW contains : Table Products: ProductID,ProductCode,ProductName,CityID,SubCategoryID... Table Cities: CityID,PriceID,City Name. Table Prices : PriceID,Price Table OrderDetails: OrderDetailsID, OrderID, FK ProductID, UnitPrice
Table order OrderID, CostomerID,...
The problem with prices : there are many prices for same product when they ordered (each city has a different price)
Well, there are multiple ways to solve a problem. It depends on whether you want to achieve speed or whether you want to have a normalized database. Here's what I would have done:
Have a table called Products: ProductID, ProductCode, ProductName,...
Have a table called Cities: CityID, City Name
Have a table called Prices: PriceID, Price
Have a table for mapping products with prices and cities, ProductPrice: ProductID, CityID, PriceID
Pro: This way your data remains in a normalized form which is considered to be a good design approach.
Con: You have to perform multiple joins while fetching data which will hamper performance a bit. But, I don't think you have millions of cities. So, I won't be bothered much with that.

What have you tried so far? Where are you stuck and need help?
Here is what is expected of enquirers:
1. TRY first what you want to do! You may find that it's not that hard.
2. Formulate what was done by you that looks like an issue/not working.
The amount of 0 items will make a problem with Mycroft Holmes' answer - that line won't show up.
You need the numbers from 0-23 (somehow generated, or make a table "Hours" with those values, and then JOIN the query suggested by Mycroft Holmes to it, and replace NULL values with 0.
I have visits table for my patients database. I have created_date field which is timestamp with CURRENT_TIMESTAMP and closed_date with datetime datatypes. I have no problem with the created_date but when I close the file using this command:
Not sure how created_date is equal to closed_date.
Make sure, that when you create a patient, at that time populate the created_date field (not closed_date - keep it blank)
At the time of closing the patient, just update the closed_date for that patient, something like:
UPDATE visits SET closed_date = GETDATE() WHERE visit_id = param_visit_id;
