[Hibernate-JIRA] Created: (HHH-2453) Inserting BIT to PostgreSQL table
by Imran M Yousuf (JIRA)
Inserting BIT to PostgreSQL table
---------------------------------
Key: HHH-2453
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2453
Project: Hibernate3
Type: Bug
Components: query-sql
Environment: Not sure about the hibernate version but will add it soon, downloaded last June. PostrgreSQL 8.2.3 on RedHat Fedora Core 1. Spring Framework.
Reporter: Imran M Yousuf
Attachments: CallUser.hbm.xml, hibernate_pgsql.properties
I created a Table which has a column active as Boolean in the entity and the HBM file specifies the type as boolean. When I use this configuration with MySQL it works fine, but when I use it with PostgreSQL I get an javax.sql.BatchUpdateException. so later I changed the HBM file 'active' column type to 'yes_no' and than it works fine. So I confirmed that the problem is due to the BIT(1) column.
So I next tried to manually insert into the column and it PgSQL tells that 1 needs to be casted. Please let me know if I can help in other ways, I will be most grateful to help.
Thank you,
Imran

[Hibernate-JIRA] Created: (HHH-3202) Problem with different aliases in select and where clauses
by Neil Hart (JIRA)
Problem with different aliases in select and where clauses
----------------------------------------------------------
Key: HHH-3202
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3202
Project: Hibernate3
Issue Type: Bug
Components: build
Affects Versions: 3.2.6, 3.2.5
Environment: Oracle 10G, Java 1.5.0_11
Reporter: Neil Hart
Our code is usually building the following query:
* criteria query */ select
this_.ID as ID2_0_,
this_.rateDate as rateDate2_0_,
this_.ticker as ticker2_0_,
this_.currency as currency2_0_,
this_.rate as rate2_0_
from
BbgDailyRateData this_
where
this_.rateDate between to_date('2008-03-24 00:00:00', 'YYYY-MM-DD HH24:MI:SS')
and to_date('2008-03-24 23:59:59', 'YYYY-MM-DD HH24:MI:SS')
and this_.currency='USD'
Every night we bounce our 4 servers and once or twice a week a server will end up trying to run the query as:
/* criteria query */ select
dailybbgra0_.ID as ID2_0_,
dailybbgra0_.rateDate as rateDate2_0_,
dailybbgra0_.ticker as ticker2_0_,
dailybbgra0_.currency as currency2_0_,
dailybbgra0_.rate as rate2_0_
from
BbgDailyRateData dailybbgra0_
where
this_.rateDate between to_date('2008-03-23 00:00:00',
'YYYY-MM-DD HH24:MI:SS') and to_date('2008-03-23 23:59:59', 'YYYY-MM-DD
HH24:MI:SS')
and this_.currency='USD'
without any changes to code or configuration. We quickly notice the problem and restart the server and the problem goes away.
The Java we are running is (using Spring):
return getHibernateTemplate().executeFind(new HibernateCallback() {
public Object doInHibernate(Session session) throws HibernateException, SQLException {
Date from = DateUtils.getStartOfDay(date);
Date to = DateUtils.getEndOfDay(date);
Criteria criteria = session.createCriteria(DailyBbgRateData.class);
criteria.add(Expression.between("date", from, to));
criteria.add(Expression.eq("currency", currency));
return criteria.list();
}
});
The mapping is:

This problem has been persistent from Hibernate 3.2.5.ga and 3.2.6.ga. The Java is 1.5.0_11 and the database is Oracle 10G.
This is the first query that we run on startup that has the problem. Once we see this query failing, other queries for different classes fail with the same alias problem. Anyone have any ideas.
I think this might be related to HHH-2847; which was also not repeatable but does repeats.
Thanks

informix 10 BLOB type
---------------------
Key: HHH-2523

Informix Dynamic Server 10.00.FC5W4
IBM Informix JDBC Driver for IBM Informix Dynamic Server 3.00.JC2
Reporter: Nick Airey
Priority: Minor
Attachments: Informix10Dialect.java
Informix 10.0 and driver 3.0 supports the BLOB type, however the hibernate dialect file does not have this type registered.
Options for fixing would be to modify the existing InformixDialect, or (better) extend to a new class as per code snippet below, which is working fine for me.
package additional.hibernate;
import java.sql.Types;
import org.hibernate.dialect.InformixDialect;
/**

*/
public class Informix10Dialect extends InformixDialect {
public Informix10Dialect() {
super();
// register support for BLOB type in informix 10
registerColumnType( Types.BLOB, "blob" );
}
}

I have a simple object model composed from three classes with their relationship as described above by mapping file.

[Hibernate-JIRA] Created: (ANN-606) Annotation Validation: @Immutable annotation does not throw error or warning on usage on subclass
by Paul Singleton Kossler (JIRA)
Annotation Validation: @Immutable annotation does not throw error or warning on usage on subclass
--------------------------------------------------------------------------------------------------
Key: ANN-606
URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-606
Project: Hibernate Annotations
Issue Type: Bug
Components: binder, documentation
Affects Versions: 3.3.0.ga
Environment: Hibernate3, Annotations.3.3.0
Reporter: Paul Singleton Kossler
The @Immutable annotation does not throw a configuration error when used on a subclass. The action required depends upon the decision in a bug/patch request for adding mutable=false to subclasses. In the current rule set the Mapping Schema for pre annotations is leveraged to define the legallity of declaring a mapped object Immutable. Base/Root classes allowed, child classes of Mutable=true not allowed, in either case the mutability of an object is directly dependent upon the mutability of the root mapped object in the object hierarchy.
The following documentation sources do not mention the issue in relation to the @Immutable annotation:
* online/down-loadable Hibernate-Annotations
* Java Persistence with Hibernate (ISBN: 1-932394-88-5)
If the rules outlined above are accurate or not: A validation error or warning should be thrown from Configuration during the loading of an incorrectly mapped class. The current method is to check the Annotations at bind time, and only at the "correct" location. This meta-rule validation should occur during the binding of a mapping to the Configuration, quickly indicating an error. Using the "older" xml based mapping this occurs when the schema (xsd) validates the mapping file (xml).

Merge does a useless refresh of a non-cascaded OneToMany List before de-initializing that List (testcase PATCH)
---------------------------------------------------------------------------------------------------------------
Key: EJB-347
URL: http://opensource.atlassian.com/projects/hibernate/browse/EJB-347
Project: Hibernate Entity Manager
Issue Type: Improvement
Components: EntityManager
Affects Versions: 3.3.2.GA
Reporter: Geoffrey De Smet
Testcase patch attached.
When merging a detached Author which had it's songs fetched (but there is no cascading to those songs),
hibernate first does a useless check if all those songs still exist (but doesn't check their optimistic lock),
and then returns the Author with a not intialized songs list.
That check is very inconsistent:
- if a song has been updated, it works, except that it shows an n +1 query problem (wihen not using BatchSize)
- if a song has been deleted, it crashes, even though the merge isn't cascaded. It doesn't give an OptmisticLockingException, but this exception:
javax.persistence.EntityNotFoundException: Unable to find org.hibernate.ejb.test.cascade.Song with id 51
If this behaviour is mandated by the JPA spec, an annotation, much like @OptimisticLock(excluded = true), to turn off this unwanted behaviour, would be wonderfull :)
