Hibernate version: 3.2
Spring 2.0
Database: Sybase 12.5


We have to tables, exactly the same as Parent and Child, one-to-many relationship. My problem is, the Child table has no primary key, only foreign key (which of course can be duplicated). How will I write my hibernate XML mapping for these tables?

Many thanks

Does your child have any combination of columns which is:
a) unique
b) not null

?
