I\'m working on a datamodel that has a set of types that share some common fields such as Id, Name, Description. To be more concrete:
I have a table used for multiply type of category and it contains a Discriminator column named \'ClassName\' to specify the type of object t开发者_如何学Pythono load. The ClassName column is non nulla
I have 4 classes A, B, B1, B2 with inheritance mapping described as below: A (mapped to table A) is the top-most parent class and its inheritance mapping strategy is tablePerHierarchy=false (means eac
Let\'s assume I have a User class and two subclasses Employee and Customer. I implemented this hierarchy as a table-per-hierarchy in DB with a column for specifying the type of user. I need to return
I have an interface and a class which implements this interface. public interface IPhase { string Description { get; set; }
In a Table-Per-Hierachy scenario is it possible to discriminate on a list of possible values? e.g. for the types Color, DarkColor, LightColor
I know this should not be trivial, but so far couldn\'t find the resolution... Working with an EF4 DB-First model, using LINQ-to-Entities with POCOs which will be consumed by an MVC3 app.
Give the following structure, MyBaseClass { public int Id {get; private set;} } MySubclassWithDiscriminator : MyBaseClass {
Hey guys, I\'m trying to create a TPH mapping on a hierarchy where the discriminating clause is the classical \"IS NOT NULL\" / \"IS NULL\" case.
If i have SQL Server tables like this: Location ---------- LocationId int PK Field1 int Field2 int etc Score
