Steve Ebersole commented on HHH-4956:
-------------------------------------
Y'all are simply highlighting the varying support of
http://download.oracle.com/javase/6/docs/api/java/sql/ResultSetMetaData.h...
and
http://download.oracle.com/javase/6/docs/api/java/sql/ResultSetMetaData.h...
Drivers implement this in all kinds of different ways.
Hibernate internals are built to extract values from ResultSets using names, not indexes
so thats not an option here.
The spot where this all happens is
org.hibernate.loader.custom.CustomLoader#autoDiscoverTypes Open to suggestions, but
driver variance makes this nearly impossible imo.
Native Query returns wrong results
----------------------------------
Key: HHH-4956
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4956
Project: Hibernate Core
Issue Type: Bug
Components: query-sql
Affects Versions: 3.3.2
Environment: hibernate 3.3.2.GA , linux, oracle 10g, weblogic 10
Reporter: Akashdeep Saddi
Issue: In-case running native queries vai hibernate we have two technical ID's in the
select clause from join of two or more tables the value of all the id's is set to one
value.
Example
A.id = 1
B.id =2
select A.Id as A_ID, B.Id as B_ID from A, B where A.B_id = B.id will return 1,1 in the
result instead of 1,2
Resolution: Use Alias in-case more than one technical keys are part of select clause.
Above query works fine when changed as below
select A.Id , B.Id from A, B where A.B_id = B.id will return 1,2
