Update database record without 1st select

Hi Guys,

here is the idea: right now to update the data in database we need to perform select first

var object = Entities.FindByID<TYPE>(id);

ojbect.field = x;

uow.SaveChanges();

question. If I need to update the specific record, and I know it's id, how can I achieve it?

example

var object = new Entity();

object.id = 1;

object.field = x;

uow.SaveChanges();

which will update the record with id=1

or is there a service method, that will allow me to do something like that? That will reduce amount of round trips to DB significantly

please let me know.

(the example code is badly formatted in the Web help -- it's clearer in the API Reference on the Start menu)

    public void Test()
     {  
               objCompany = GetCompany(Id);
               objCompan.Name = "new name";
             UpdateCompany(objCompany);
     }
     public void UpdateCompany(Company objCompany)
    {
          LightSpeedContext<YourUnitOfWork> _context

         = new LightSpeedContext<YourUnitOfWork>("default");

        using (YourUnitOfWork uow = _context.CreateUnitOfWork())
        {
            uow.Attach(objCompany);
            var entity = Mindscape.LightSpeed.Testing.EntityFactory.UpdateEntityState<Company>(objCompany, EntityState.Modified);

            uow.SaveChanges();
        }
    }
