Join Table many-to-one issue

I posted this on the hibernate forum, but no help. Sorry for the repost.

I have 3 tables:



My main table is PTNT_DATA_MSRMNT_CLCTN & join table is PTNT_PRCTC_PRFMNC_YR. I want to join these 2 tables by a non-primary key in the main table (PTNT_PRCTC_PRFMNC_YR_ID), but this does not work.

Hibernate Mapping:



The Hibernate generated SQL is:

where ptntdata.PTNT_DATA_MSRMNT_CLCTN_ID=prfmncyr.PTNT_PRCTC_PRFMNC_YR_ID.

But It should rather be
ptntdata.PTNT_PRCTC_PRFMNC_YR_ID=prfmncyr.PTNT_PRCTC_PRFMNC_YR_ID.


Hibernate version : 3.2.7.ga

Can you guys help me on this. Hope my question is clear & understandable
