Hello,

I have a simple question.
If I have a table which has no key definition, and if I try to map this, what happens? I mean, can hibernate handle tables without key definition?

Actually I already tried such a thing, because I have some tables to map which have no keys, and I am not allowed to change. I could save new instances to db, but in querying there were problems.

It does not need physical PKs. It would need some means of uniquely identifing rows. The typical approach is to map it using a composite key which aggregates the columns that make the row unique.
