Question

Hi. How do I know that the DB table has a column: TypeId for some entity? I write data directly in DB from xml. This xml doesn't has TypeId attribute and for my custom query i should know, add TypeId to query from code or no.

Anton,

A DB table doesn't have the TypeId column in case the corresponding Entity has ConcreteTable inheritance scheme. In runtime it can be found by this code snippet:

var customerTypeInfo = domain.Model.Types[typeof(Customer)];
var inheritanceScheme = customerTypeInfo.Hierarchy.InheritanceSchema;
if (inheritanceScheme == InheritanceSchema.ConcreteTable)
  // TypeId column is absent

Hope that helps.
