I am using Hibernate and postgrSQL in my project . I am in a situation where I need to do self-join for a table and I want to use
one- to-many relationship for that. Where my table contains few fields in which one of the field say x field contains the value of
primary key which can be null. Now sometimes I need to fetch records which have identical values in field x.
how do i configure this in hbm.xml ?
