Question

I have the following tables

Entity
id,name,categoryid
21,’Blah’,1

EntityCategory(Enum table)
id, name
1,’New Blahs’

I have a FK relationship between Entities->categoryid and EntityCategories->id

I have generated SubSonic classes for both as well a corresponding Model object for Entity
class Entity{ID,Name,CategoryName}

I am trying to return the Model.Entity type with category name filled in i.e.

public Entity GetEntityByName(string name){   return new      Select(       Entity.IdColumn,           Entity.NameColumn,       EntityCategory.NameColumn)    .From(Entity.Schema)    .InnerJoin(Tables.EntityCategory)    .Where(Entity.NameColumn).IsEqualTo(name)    .ExecuteSingle<Model.Entity>(); 

Needless to say this is not working. I actually get a Model.Entity with the Entity.Name set to the EntityCategoryName.

If you use SubSonic 3.0 you can do this with projection:

var result = from e in db.Entities where e.ID=1 select new Entity{    ID=e.ID,    name=e.Name,     CategoryName=(CategoryName)e.CategoryID } 

With SubSonic 2.x, I’d say to make it easy on yourself and extend the partial class with a readonly enum:

public partial class Entity{    public CategoryName{      return (CategoryName)this.CategoryID;    } }
