sql server - How to make tables in a database -


I am creating a database about the cars that go around a certain road, so I created a table which is a car ID And the day the car crosses the special road car can pass millions of times by road, I know that to keep all the dates I need to make another table but I am confused. Please help. How should the database be shown

Without knowing what database you are using, I will assume that MS SQL Server / SQL Express should satisfy your requirements. 

  - Create personalized personalized store details table (identification id identification (1,1) primary key, Registration varchar (10), varchar (20), model varchar (50) - any other field here Add) Go - place passes through a "known" car About each time create a store description table (ID int identity (1,1) Primary key, CarID int is not zero, obstruction Sightings_FK_Car foreign key (carid) Reference car ( ID), add any other field to the current time)

Using the meaningless integer as the primary key on the tables is a personal choice. You can use a combination of some car registration and other time viewing time as the primary key on the first table, like the registration number of the car. I like the meaningful integer for the reasons for the execution.

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ
