Using slugs on database for categories names and others

Question

Hello,
I have the following SQL Categories table:
    create table dbo.Categories (
      Id int not null primary key clustered (Id),
      Name nvarchar (40) not null
        constraint UQ_Genders_Name unique (Name)
On an ASP.NET MVC application I need to display products by category but I would like the url to be meaningful, something like:
    http://mydomain.com/books-and-magazines
So I suppose I need a slug field in my database. But should the slug be unique?
On the MVC application I could also use the following url:
    http://mydomain.com/2/books-and-magazines
Where 2 is the id of the category and now I would look by id ...
Or should I create a slug which would be equal to "name converted to slug" + id so:
    http://example.com/books-and-magazines-2
How is this usually done on the MVC side and on the SQL side?
And if a name changes should I change the slug?
Is there a way to generate the slug on the database?
Thank You,
Miguel
