Hibernate : <One-to-one> Filter Required

[CatchSandeepVaid]

Consider this scenatio :
I have one-to-one relation between Product and ProductBasic BUT at database level i have one-to-many between
PRODUCT and PRODUCTBASIC tables as history is mainted in the same table :

PRODUCT ----> PID (PK)
PRODUCTBASIC ---> PID (FK), USECODE forms Composite-key

PRODUCT
PID PNAME
1 Pen

PRODUCTBASIC
PID USECODE STARTTIME ENDTIME
1 100 06-MAY-2009 11:00 07-MAY-2009 10:00
1 100 07-MAY-2009 10:00 31-DEC-9999 00:00

Now while querying for ProductBasic, i will always fetch the row which satisfies the condition STARTTIME<CURRE NTTIME<ENDTIME
and this will surely return me only one row.

Ideally the generated sql query should be :

select * from PRODUCT product left outer join PRODUCTBASIC productbasic on '100'=productba sic.USETYPE
and product.PID=pro ductbasic.PID
and (
productbasic.ST ARTTIME<'09-MAY-2009 10:00'
and '09-MAY-2009 10:00'<productb asic.ENDTIME
)
where
product.PID='1'

1.) You have not posted a question.
2.) If you have a hibernate question better post it in a hibernate forum.
If you have an SQL problem then better post it in the relevant SQL forum.

This is a hibernate question only.. I want to know what to do in this situation...
Can i post hibernate questions in bytes forum ?

[r035198x]

You can and you have. You are likely to get more help in a hibernate forum though than in a Java forum. You also never specified a question.

&lt;One-to-one&gt; Filter Required

Have you managed to find a good solution for this problem? I'm now having the exact same issue and trying to understand what is the best way to solve it.

What is the specific problem? What are you trying to accomplish, how are you going about it, and what are the results you're getting now?

HI,
The problem is i want that certain conditions to be always applied for a particular one-to-one association. Filters are meant for this in hibernate but we cant apply filters to one-to-one associations in hibernate.

I implemented this functionality myself and tried to contribute this to Hibernate @ Hibernate Jira site but i am not satisfied with their response.
