c# - Cloning an entity in NHibernate? -

-

i want save single object database twice. have code:

using (var ss = nhibhelp.opensession()) using (var tt = ss.begintransaction()) {     var entity = new entity();      ss.save(entity);     ss.save(entity);      tt.commit(); }

but results in 1 row being added database. how insert single object database twice (with 2 different ids) ?

you shouldn't - nhibernate maintains "object identity" within it's session, not differentiate between ..well.. same object. advise against this, , better solution @ way of cloning object (either via reflection, or clone method), , saving cloned object.

if want ignore advice above, can work evicting entity session, setting it's id it's unsaved value (depends on mapping, 0), , saving again.

it might work if called session.merge(entity) twice (you have reset id it's unsaved value after first call).

alternatively use stateless session session.merge() , don't have evict entity between save's.
