primaryKeysForNewRowsWithEntity(self, count, anEntity)Generates and returns a list of dictionaries, whose keys are PK attributes' names and values the corresponding PK value. This implementation executes the following SQL statement: SELECT PK_SEQ_<entity.primaryKeyRootName()>.NEXTVAL FROM DUAL If 'anEntity' defines more than one PK (compound primary key), returns an empty list.
