We subclass Hardware to Door and then to DoorCU001, Using single table strategy and DiscriminatorType.String and then DiscriminatorValue on each subclass
When we try to select all an DoorCU001 we get an SQL error that column DoorCU001 doesn't exsist and when we look and compare to listing Door then we see that the WHERE clause in the generated SQL differs in that type = 'Door' and this works but for DoorCU001 the clause looks like type = DoorCU001 which by all means are incorrect SQL.
Is this a known bug?
