Emmanuel Bernard commented on ANN-210:
--------------------------------------
My idea was to have a
@JoinColumnOrFormulas
which contains an array of
@JoinColumnOrFormula(
joinColumn=@JoinColumn, formula=@Formula
)
The rational behind that is to be able to keep the column ordering even if formula and
columns are mix and matched
I am also considering having an org.hibernate.annotations.JoinColumn, I think some
information might belong here (i need ot double check)
Look for AnnotationBinder and the use of Ejb3JoinColumn and Ejb3Column, the idea is to
convert the new annotations into the Ejb3*Column object. HbmBinder is the reference on how
actully map using the internal model
@ManyToOne not working wth @Formula
-----------------------------------
Key: ANN-210
URL:
http://opensource.atlassian.com/projects/hibernate/browse/ANN-210
Project: Hibernate Annotations
Issue Type: Improvement
Components: binder
Affects Versions: 3.1beta7
Environment: Hibernate 3.1, PostgreSQL 8.1.1
Reporter: Jason Long
This type of mapping fails:
@ManyToOne
@Formula(value="( select v_pipe_offerprice.offerprice_fk from v_pipe_offerprice
where v_pipe_offerprice.id = id )")
public OfferPrice getOfferPrice() { return offerPrice; }
While the following mapping works as expected:
<class name="Pipe" table="t_pipe">
...
<many-to-one name="offerPrice"
class="pipetracker.model.price.OfferPrice"
formula="( select v_pipe_offerprice.offerprice_fk
from v_pipe_offerprice
where v_pipe_offerprice.id = id )"/>
...
</class>
This is not being treated as a formula because the generated SQL included a referece to
the field pipe.offerprice_id which does not exsist because this is a virtual column
calculated from a view.
