CLONE -Impossible to define caching for a subclass's collection in hibernate.cgf.xml
-------------------------------------------------------------------------------------
Key: HHH-2808
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2808
Project: Hibernate3
Issue Type: Bug
Components: caching (L2)
Affects Versions: 3.2.5
Environment: Hibernate 3.2.5
Sybase
Reporter: Sebastien Blind
Basically, hibernate allows to define <cache usage="transactional"/> inside the subclass mapping, i.e.
<subclass name="SubClass" extends="BaseClass" discriminator-value="xxx">
<bag name="subClassLinks" lazy="false" inverse="true" batch-size="100">
<cache usage="transactional" region="xxx"/>
<key column="xxx" not-null="true"/>
<one-to-many class="xxx"/>
</bag>
<join table="xxx">
</join>
</subclass>
but it's not allowed to do the same using <collection-cache collection="subClass.myCollection" region="xxx" usage="transactional"/>.
It throws:
Exception in thread "main" org.hibernate.MappingException: Cannot cache an unknown collection: subClass.myCollection
at org.hibernate.cfg.Configuration.setCollectionCacheConcurrencyStrategy(Configuration.java:1984)

[Hibernate-JIRA] Created: (HHH-2851) ParameterTranslationsImpl fails to correctly determine parameter type

ParameterTranslationsImpl fails to correctly determine parameter type
---------------------------------------------------------------------
Key: HHH-2851
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2851
Project: Hibernate3
Issue Type: Bug
Components: query-hql
Affects Versions: 3.2.5
Reporter: Alex Savitsky
Priority: Minor
For the conditions in the form "(:param IS NULL OR alias.someField = :param)", the HQL parses would not correctly determine the type of param, unless the conditions are swapped like "(alias.someField = :param OR :param IS NULL)". The reason is that NamedParamTempHolder classes are created for all parameter entries, in the order they appear in the query. The first occurrence (:param IS NULL) would have its expectedType set to null, and the second occurrence would use the param holder created by the first occurrence, without checking whether it can improve it in any way (which it can - the expectedType for second occurrence is correctly determined to be Long).
Proposed fix would be to check for this particular condition, enhancing paramHolder if possible, with new information:
old code:
if ( paramHolder == null ) {
paramHolder = new NamedParamTempHolder();
paramHolder.name = namedSpec.getName();
paramHolder.type = namedSpec.getExpectedType();
namedParameterMap.put( namedSpec.getName(), paramHolder );
}
new code:
if ( paramHolder == null ) {
paramHolder = new NamedParamTempHolder();
paramHolder.name = namedSpec.getName();
paramHolder.type = namedSpec.getExpectedType();
namedParameterMap.put( namedSpec.getName(), paramHolder );
+ } else if (paramHolder.getExpectedType() == null && namedSpec.getExpectedType() != null) {
+ paramHolder.type = namedSpec.getExpectedType();
}

Creating a mapping from a column in one table to a non-primary key column in another table produces incorrect mapping file missing a property-ref to the non-primary key.
How to reproduce using Apache Derby:
Create a database and connect to the database.
jdbc:derby://localhost:1527/myDB;create=true;user=me;password=mine
Create these tables in the myDB database, in the ME schema.
create table vehicles (
make_id integer,
model_id integer,
name varchar(50),
PRIMARY KEY (make_id, model_id)
);
create table owners (
owner_id integer PRIMARY KEY,
favorite_make_id integer,
name varchar(20)
);
-- optional content
insert into vehicles values (1, 10, 'Chevrolet Corvette');
insert into vehicles values (2, 11, 'Ford Focus');
insert into vehicles values (3, 12, 'Honda Accord');
insert into vehicles values (4, 13, 'Toyota Camry');
insert into owners values (50, 3, 'Jim');
insert into owners values (51, 1, 'Alex');
insert into owners values (52, 4, 'Sue');
insert into owners values (53, 1, 'Casey');
Create this Hibernate Configuration file.
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

</hibernate-configuration>
Setup a Hibernate Console Configuration with the configuration above and connection to the Derby database.
Create this Hibernate reverse engineering configuration
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-reverse-engineering PUBLIC "-//Hibernate/Hibernate Reverse Engineering DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-reverse-engineering-3.0.dtd" >

<foreign-key foreign-table="OWNERS">
<column-ref local-column="MAKE_ID" foreign-column="FAVORITE_MAKE_ID" />
</foreign-key>
</table>
</hibernate-reverse-engineering>
Setup a Hibernate Code Generation configuration like in the attached images.
Running the Code Generation configuration will produce this Vehicles.hbm.xml mapping file.
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"

The above mapping should use the "priority" field to the ordering.
SQL that is produced is :
select criteria0_.RoutingRuleId as RoutingR1_1_, criteria0_.CriteriaComponentId as Criteria2_1_,
criteria0_.ListIndex as ListIndex1_,
routingcri1_.id as id73_0_,
routingcri1_.creationDate as creation3_73_0_,
routingcri1_.description as descript4_73_0_,
routingcri1_.lastModificationDate as lastModi5_73_0_,
routingcri1_.name as name73_0_,
routingcri1_.predefined as predefined73_0_,
routingcri1_.status as status73_0_,
routingcri1_.priority as priority73_0_,
routingcri1_.visible as visible73_0_,
routingcri1_.matcher_id as matcher25_73_0_,
routingcri1_.criterion_id as criterion27_73_0_,
routingcri1_.location_id aslocation26_73_0_,
routingcri1_.RoutingComponentType as RoutingC1_73_0_
from odp_rulecriteriajoin criteria0_
left outer join odp_routingcomponent as routingcri1_ on criteria0_.CriteriaComponentId=routingcri1_.id
where criteria0_.RoutingRuleId=1 order by odp_routingcomponent .priority asc
It is wrong since not the table alias is used in the order by clause, but the real table name.
Mysql fails with exception that odp_rulecriteriajoin.priority is unknown table.
Changing the query to include "order by criteria0_.priority asc" returns the correct result.

incorrect hql query on one-to-one with property-ref

I have a one-to-one relationship with property-ref between Master and Slave2.
I want to find all Master instances that have a null Slave2 instance associated.
To do so my query is
select master from Master master where master.slave2 is null
The sql generated is
select master0_.oid as oid0_, master0_.libelle as libelle0_ from Master master0_ where master0_.oid is null
which seems incorrect. It checks here Master instances with null id (config files are listed below).
If I do my query like this
select master from Master master where master.slave2.oid is null
the generated sql is ok :
select master0_.oid as oid0_, master0_.libelle as libelle0_ from Master master0_, Slave2 slave2x1_ where master0_.oid=slave2x1_.myMaster and (slave2x1_.oid is null)
I have attached a small eclipse project that reproduces the problem
This problem may-be related to the one I have submitted as issue HHH-1849

[Hibernate-JIRA] Created: (HHH-2666) subselect fetching ignores max results

subselect fetching ignores max results
--------------------------------------
Key: HHH-2666
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2666
Project: Hibernate3
Issue Type: Improvement
Components: query-hql, query-sql
Affects Versions: 3.2.1
Environment: Hibernate 3.2.1
HSQLDB 8.0
Reporter: James Roper
Priority: Minor
When maxResults is set for a query, the hibernate subselect fetching strategy ignores it. For example, I have a class entry, that has a list of comments, which are configured to use the subselect fetching strategy. You can see that in the original query, only the top ? results are fetched:
select
top ? entry0_.id as id0_,
entry0_.title as title0_,
entry0_.entry as entry0_,
entry0_.time as time0_,
entry0_.category_id as category5_0_
from
Entry entry0_
order by
entry0_.time desc
But then when it does the sub select query to lazily load the comments, this is the query it runs:
select
comments0_.entry_id as entry5_1_,
comments0_.id as id1_,
comments0_.id as id1_0_,
comments0_.time as time1_0_,
comments0_.comment as comment1_0_,
comments0_.author as author1_0_
from
Comment comments0_
where
comments0_.entry_id in (
select
entry0_.id
from
Entry entry0_
)
order by
comments0_.time desc
So, it loads every single comment in the database, even though only the comments for the top ? entries are needed. Of course, if there was no order by clause on the first query, the sub select may not return the same results, so it should probably only do this when there is an order by clause in the first query, and it should make sure it includes the order by clause in the sub select.

Need a way to specify "unsaved-value" strategy using annotations
----------------------------------------------------------------

Project: Hibernate Annotations
Issue Type: Bug
Environment: Hibernate 3.2.2, Hibernate-annotations 3.2.1
Reporter: Suji Suresh
Hibernate has two ways of specifying a value for primary key:
1. Assign a value before handing it over to Hibernate
2. Have Hibernate generate the value before persisting
In my project I have objects of both of the above specified types. In other words I assign value for the primary key for some the objects (lets call these objects "assigned") and for others I have Hibernate generate the value before persisting (lets call these objects "generated"). Since Hibernate annotations does not support "unsaved-value", I do not have a way of specifying "unsaved-value" strategy. While my "generated" objects work perfectly with Hibernate's default "unsaved-value" strategy, I see wrong (but expected) behaviour when I try to persist an "assigned" object that is already present in the database in that, I get StaleStateException instead of DataIntegrityViolationException
