Hi,

It's a basic question, but can anyone answer me?

if I want to delete a row, do I need to call session.load() before session.delete()?

and why ?

thank you

Well Im also new in Hibernate, but like I understand when you want to delete an object you need to have this object, so you can get the object with load sentence or with finder method (you need to extract specific object from list).
I'm not sure if exist other form for access an object but if you know something maybe you can tell me this.

ok,

but you can create a new instance of the object without load the object from database...



but sometimes this not work, and why not ?

thanks

From the javadoc:

Remove a persistent instance from the datastore. The argument may be an instance associated with the receiving Session or a transient instance with an identifier associated with existing persistent state.

So I guess it doesn't have to be an instance loaded with Session.load().

One question that someone else can perhaps answer is What happens if said instance has been loaded but then you call delete with a non-persistent instance? If this is illegal, could this be the source of your problems?

It has to be an instance that contains the current database state. Otherwise Hibernate doesn't know what associated objects to delete/nullify.
