I am migrating some code from hibernate2 to hibernate3 and I encountered the following while adding annotation to an entity bean: I have two fields: | @hibernate.column name = "EXT_ID" unique-key = "SECURED_OBJECTS_EXT_ID_TYPE_CODE_IDX" | | @hibernate.column name = "TYPE_CODE" unique-key = "SECURED_OBJECTS_EXT_ID_TYPE_CODE_IDX" | I noticed that both fields have the same unique-key, what does this stands for and how do I represent the unique-key in hibernate3?
