[Hibernate-JIRA] Created: (HHH-3420) MatchMode doesn't escape wildcard characters

MatchMode doesn't escape wildcard characters
--------------------------------------------
Key: HHH-3420
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3420
Project: Hibernate3
Issue Type: Bug
Components: query-criteria
Affects Versions: 3.2.2
Environment: MySQL
Reporter: Hontvári József
Priority: Minor
One can think that by specifying e.g. MatchMode.START in a "like" restriction Hibernate takes care of escaping SQL LIKE wildcard characters in the supplied pattern. It doesn't, actually Hibernate only inserts a % before the first character.
I am not sure what was the intent of the original author (Gavin King), so the issue may only be missing documentation. However I don't see any other useful purpose of this class then providing database independent escaping. It seems that all databases use the % wildcard, so there is no need to provide database indpeendence to that.
It can be argued that this might create a security problem for an unaware developer, so I set issue type to bug.

[Hibernate-JIRA] Created: (HHH-3499) NamingStrategy should support naming foreign keys and indexes

NamingStrategy should support naming foreign keys and indexes
-------------------------------------------------------------
Key: HHH-3499
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3499
Project: Hibernate Core
Issue Type: Improvement
Components: metamodel
Affects Versions: 3.3.1
Reporter: Geoffrey De Smet
hbm2ddl always generates foreign key constraints based on hashcodes, like this:
alter table apple add index FK365FA4BB24B1D45C (lemon_id), add constraint FK365FA4BB24B1D45C foreign key (lemon_id) references lemon (id);
Some databases don't support enough characters for foreign key names to generate a readable foreign key name, so that's a sensible default.
However, those of use that use databases like MySQL etc, would like a readable foreign key name, such as:
alter table apple add index FK_Apple_lemon (lemon_id), add constraint FK365FA4BB24B1D45C foreign key (lemon_id) references lemon (id);
We can do that by annotating every entity with @Index in JPA, or specifying it in a hbm file,
but we can't do it generally, by extending DefaultNamingStrategy or ImprovedNamingStrategy.
Here's a proposition on how we could do it:
- In the NamingStrategy interface, next to the method foreignKeyColumnName, add a method:
public String foreignKeyConstraintName(String propertyName, String propertyEntityName, String propertyTableName, String referencedColumnName
- DefaultNamingStrategy and ImprovedNamingStrategy should implement it as it is now, based on hashcodes.
- If a mapping has an @Index JPA annotation or it's specified in a hbm file, that override counts.

[Hibernate-JIRA] Created: (HHH-2355) CGLIBLazyInitializer can not access a public member if parent class is not public
by Daniel Beland (JIRA)
CGLIBLazyInitializer can not access a public member if parent class is not public
---------------------------------------------------------------------------------
Key: HHH-2355
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2355
Project: Hibernate3
Type: Bug
Versions: 3.2.1
Reporter: Daniel Beland
In hibernate 3.2.1, CGLIBLazyInitializer cannot acces a public method if it has been inherited from a parent class that is not public.
Let's say we have a class A, modifier = default (package) with a public method getName() (and setName(String name)).
Then I create a public class B that extends A.
in my code I can retrieve B from the database:
B b = session.load(B.class, new Integer(1), LockMode.NONE);
I receive b with all the values set correctly (So at this point, Hibernate was able to use the method setName() correctly).
In my code if I then try to use b.getName(), I receive and error:
java.lang.IllegalAccessException-->Class org.hibernate.proxy.pojo.cglib.CGLIBLazyInitializer can not access a member of class A with modifiers "public"
But I am not trying to access A.getName(), but B.getName() (which is a public method in a public class).
This was working perfectly with Hibernate 2.1.7c and 3.1.3.
The full information about my problem can be found here: http://forum.hibernate.org/viewtopic.php?t=969453

Can not get N first results of query with DB2 dialect (neither with setMaxResults nor with setFetchSize)
--------------------------------------------------------------------------------------------------------

Components: query-criteria

Version du pilote JDBC : 2.1.34
Using dialect: org.hibernate.dialect.DB2Dialect
Reporter: Fred
I can't get the N first records from a select request using the setMaxResults method.
HB generates a request that can not be understood by DB2 (select * from ( select rownumber() over() as rownumber etc.... see first stacktrace below)
Moreover, using setFetchSize does not work (see second stack trace below the first one).
Is there a way to tell HB to append " fetch first 10 rows only" to the query (as a workaround) ? Because my DB2 can understand that one :
select *
from MYTABLE
where numseq = '2'
fetch first 10 rows only
thanks !
Fred
