[hibernate-dev] [ORM] Support for upsert semantics

Hi, A common requirement that comes up repeatedly is "upsert" operations, i.e. either insert a record or update the existing one with the same PK, if it already exists. Many (most?) RDBMS support it, either by implementing SQL 2003's MERGE keyword or via proprietary alternatives [1]. I think it'd be great if there was something like Session#upsert(), exposing these semantics at the entity level. Perhaps the idea was already brought up in the past, but I wanted to throw it out in any case. Any thoughts?
