I have following situation:

Entity Company:
ID (PK)
OtherUniqueID (FK)
Name
...

Entity Reports:
ID (PK)
Year
Month
OtherUniqueID (FK)
...

Each Company can have 0-n Reports. The reports are not related to the Company through the company's PK but throught the field OtherUniqueID, which in the Company entity is unique.

How can I map this in NHibernate?

Thanks for any suggestions!

This can be done via the property-ref attribute of the many-to-one element. This attribute specifies the property of the "one" side to create the relation on.

Example:

Code:

<many-to-one column="OtherUniqueID" outer-join="false" name="EntityCompany" property-ref="OtherUniqueID" class="Namespace.EntityCompany, AssemblyName"/>
