When I get objects from DB and observe somthing wrong.
My select in java code is:
Code:
select rq from RMSTRequirementHistDTO as rq where rq.id = ?
My mapping from logs is:
Code:
- Mapped property: tempId -> TEMPID, type: long
- Mapped property: id -> RESID, type: long
It is ok. It is the same like in my hbm mapping file.
I have diferent between my HQL and SQL genetared by hibernate:
... where rq.
id = ?
... where (rmstrequir0_.
TEMPID=? )
I can see it in logs:
Code:
- HQL: select rq from xxx.RMSTRequirementHistDTO as rq where rq.id = ?
- SQL: select rmstrequir0_.TEMPID as x0_0_ from RMST_REQUIREMENTHIST rmstrequir0_ where (rmstrequir0_.TEMPID=? )
TEMPID is id ( primary key ) of my class.
But I want to ask about objects with special id not tempid.
What is wrong?!
