sql - Can I set NHibernate's default "OrderBy" to be "CreatedDate" not "Id"? -

-
this oddball question figure. can nhibernate ask sql sort data createddate default unless set orderby in hql or criteria? i'm interested in knowing whether sort can accomplished @ db level avoid bringing in linq. the reason use guids ids , when this: sheet sheet = sheetrepository.get(_someguid); ilist<sheetlineitems> lineitems = sheet.lineitems; to fetch of lineitems, come in whatever arbitrary way sql sorts fetch, figure guid. @ point i'll add ordinals line items, now, want use createddate sort criteria. don't want forced do: ilist<sheetlineitem> lineitems = sheetlineitemrepository.getall(_sheetguid); and writing method sort createddate. figure if sorted on createddate default, fine, unless requested otherwise. no, can't. best solution (as mention in comment) set order-by attribute in collection mapping . note value should set database column name, not property name.
