Good morning,

I've a two legacy tables named A and P, linked by a Many-To-One relation.

The problem is that the link is not made to the primary key, but to two fields ("code" and "type") in table P whose combination is unique.

I'm aware of the "property-ref" semantic to link to a (single!) column other than the primary key.

My question is : does Hibernate support a "property-ref" link to more than one column (i.e., a "composite-property-ref") ? How ?

Something like (A.pcode + A.ptype) -> (P.code + P.type)

I'm using Hibernate 2.1.4

Thanks a lot,

Martin

You will need to upgrade to v 3 and use new properties mapping tag.
