We work with a legacy database where foreign keys contain 0 instead of null. Is there a way to make Hibernate interpret 0 as null for certain fields?

Thank you,

Another option is to implement a custom UserType that does the 0<->null translation. You can find some information here: http://www.hibernate.org/hib_docs/v3/re ... pes-custom
