[Hibernate-JIRA] Created: (HHH-1994) Problem with case sensitive column and tables names and Identity mapping with postgreSQL

Problem with case sensitive column and tables names and Identity mapping with postgreSQL
----------------------------------------------------------------------------------------
Key: HHH-1994
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1994
Project: Hibernate3
Type: Bug
Components: core
Versions: 3.1.3
Environment: Hibernate 3.1.3, Java 1.5.0_07 (sun) windos and linux ( 32 & 64 bit). POstgres SQL 8.1 Windows and linux
Reporter: Alex Samad
Whilst trying to insert into a table with a primary key (ID mapping) which has a identity generator. And the columns and/or the table has been defined with case sensitivey ie back ticks.
It fails to get the next serial number and thus fails any inserts.
The problem lies in dialect/PostgreSQLDialect.java
public String getIdentitySelectString(String table, String column, int type) {
return new StringBuffer().append("select currval('")
.append(table)
.append('_')
.append(column)
.append("_seq')")
.toString();
}
table is inclosed in quotes and column is inclosed in quotes which gives a name like
"table"_"Column"_seq - which fails
I would suggest a fix is to test each of table or column for " and if it exist then to strip it of both of table and column and encluse the whole name in "". This mighe break some old code where say the table is coded in case insensitive table name and case sensitive column key.
Sorry not much of a java programmer.

[Hibernate-JIRA] Created: (HHH-5025) Support caching audit queries using ehcache's DiskStore.

Support caching audit queries using ehcache's DiskStore.
--------------------------------------------------------
Key: HHH-5025
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5025
Project: Hibernate Core
Issue Type: Improvement
Components: envers
Reporter: Brent Worden
Priority: Minor
Enabling audit query caching with a ehcache cache configured as persisting to disk or overflowing to disk. For example,
<defaultCache diskPersistent="true" eternal="false" maxElementsInMemory="1000" maxElementsOnDisk="10000" overflowToDisk="true" timeToIdleSeconds="300" timeToLiveSeconds="3600" />
Results in the following exception:
java.io.NotSerializableException: org.hibernate.envers.entities.RevisionTypeType
at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1156)
at java.io.ObjectOutputStream.defaultWriteFields(ObjectOutputStream.java:1509)
at java.io.ObjectOutputStream.writeSerialData(ObjectOutputStream.java:1474)
at java.io.ObjectOutputStream.writeOrdinaryObject(ObjectOutputStream.java:1392)
at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1150)
The lack of needed serialization prohibits the use of ehcache's DiskStore.

[Hibernate-JIRA] Created: (HHH-3325) Pagination with Oracle ROWNUM is sub-optimal

Pagination with Oracle ROWNUM is sub-optimal
--------------------------------------------
Key: HHH-3325
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3325
Project: Hibernate3
Issue Type: Bug
Affects Versions: 3.2.5
Reporter: e. wernli
Pagination with Oracle ROWNUM is sub-optimal
The feature works but result in sub-optimal SQL. The generated SQL is the following:
select * from ( select row_.*, rownum rownum_ from ( select this_.id as id3_0_, this_.version as version3_0_, this_.name as name3_0_, this_.type as type3_0_, this_.marketstatus as marketst5_3_0_ from Customer this_ order by this_.id asc ) row_ ) where rownum_ <= ? and rownum_ > ?
But this SQL is faster:
SELECT *
FROM (SELECT row_.*, ROWNUM rownum_
FROM (SELECT this_.ID AS id3_0_, this_.VERSION AS version3_0_,
this_.NAME AS name3_0_, this_.TYPE AS type3_0_,
this_.marketstatus AS marketst5_3_0_
FROM customer this_
ORDER BY this_.ID ASC) row_
WHERE ROWNUM <= ?)
WHERE rownum_ > ?
The second solution allows Oracle to use an optimization that can dramatically reduce the time of the query, especially one of the first page is retrieved.
See this link for an explanation of this optimization: http://decipherinfosys.wordpress.com/2007/08/09/paging-and-countstopkey-o...

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

[Hibernate-JIRA] Created: (HHH-3839) Using Criteria.setMaxResults gives a MySQLSyntaxErrorException

Using Criteria.setMaxResults gives a MySQLSyntaxErrorException
--------------------------------------------------------------
Key: HHH-3839
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3839
Project: Hibernate Core
Issue Type: Bug
Affects Versions: 3.3.1
Environment: MySQL 5.0.51a
Reporter: Kevin DIMEY
Attachments: hibernate.cfg.xml
Hi,
When trying to limit the number of rows returned by Criteria.list() method, exception is thrown about bad SQL grammar. The "limit" SQL statement is put just after the select keyword. It should be placed at the end of the request.
Moreover, it seems there is no coma between the start row and the amount of objects to retrieve.
Here is the method called :
session.createCriteria(Etude.class).setFirstResult(5).setMaxResults(10).list();
I get the same issue while using only setMaxResults, it puts the "top" keyword just after the "select" one.
Here is the request generated and the stack trace :
Hibernate: select limit ? ? this_.id as id7_6_, this_.avorte_id as avorte11_7_6_, this_.confidentielle as confiden2_7_6_, this_.contact_id as contact12_7_6_, this_.created_at as created3_7_6_, this_.date_fin as date4_7_6_, this_.date_signature as date5_7_6_, this_.date_sollicitation as date6_7_6_, this_.entreprise_id as entreprise13_7_6_, this_.etat_code as etat7_7_6_, this_.numero as numero7_6_, this_.sujet as sujet7_6_, this_.updated_at as updated10_7_6_, avortement2_.id as id1_0_, avortement2_.created_at as created2_1_0_, avortement2_.created_by as created3_1_0_, avortement2_.raison as raison1_0_, contact3_.id as id2_1_, contact3_.adresse_id as adresse18_2_1_, contact3_.civilite_code as civilite2_2_1_, contact3_.connu_par_code as connu3_2_1_, contact3_.connu_par_detail as connu4_2_1_, contact3_.created_at as created5_2_1_, contact3_.entreprise_id as entreprise19_2_1_, contact3_.fax as fax2_1_, contact3_.fonction as fonction2_1_, contact3_.mail as mail2_1_, contact3_.news_dernier_envoi as news9_2_1_, contact3_.news_desinscrit as news10_2_1_, contact3_.nom as nom2_1_, contact3_.parti as parti2_1_, contact3_.prenom as prenom2_1_, contact3_.service_code as service14_2_1_, contact3_.tel_fixe as tel15_2_1_, contact3_.tel_portable as tel16_2_1_, contact3_.updated_at as updated17_2_1_, adresse4_.id as id0_2_, adresse4_.adresse1 as adresse2_0_2_, adresse4_.adresse2 as adresse3_0_2_, adresse4_.adresse3 as adresse4_0_2_, adresse4_.code_postal as code5_0_2_, adresse4_.ville as ville0_2_, entreprise5_.id as id5_3_, entreprise5_.adresse_id as adresse14_5_3_, entreprise5_.created_at as created2_5_3_, entreprise5_.disparue as disparue5_3_, entreprise5_.domaine_code as domaine4_5_3_, entreprise5_.effectif_code as effectif5_5_3_, entreprise5_.etat_code as etat6_5_3_, entreprise5_.fax as fax5_3_, entreprise5_.nom as nom5_3_, entreprise5_.num_siret as num9_5_3_, entreprise5_.particulier as particu10_5_3_, entreprise5_.site_web as site11_5_3_, entreprise5_.tel as tel5_3_, entreprise5_.updated_at as updated13_5_3_, adresse6_.id as id0_4_, adresse6_.adresse1 as adresse2_0_4_, adresse6_.adresse2 as adresse3_0_4_, adresse6_.adresse3 as adresse4_0_4_, adresse6_.code_postal as code5_0_4_, adresse6_.ville as ville0_4_, entreprise7_.id as id5_5_, entreprise7_.adresse_id as adresse14_5_5_, entreprise7_.created_at as created2_5_5_, entreprise7_.disparue as disparue5_5_, entreprise7_.domaine_code as domaine4_5_5_, entreprise7_.effectif_code as effectif5_5_5_, entreprise7_.etat_code as etat6_5_5_, entreprise7_.fax as fax5_5_, entreprise7_.nom as nom5_5_, entreprise7_.num_siret as num9_5_5_, entreprise7_.particulier as particu10_5_5_, entreprise7_.site_web as site11_5_5_, entreprise7_.tel as tel5_5_, entreprise7_.updated_at as updated13_5_5_ from etude this_ left outer join avortement avortement2_ on this_.avorte_id=avortement2_.id left outer join contact contact3_ on this_.contact_id=contact3_.id left outer join adresse adresse4_ on contact3_.adresse_id=adresse4_.id left outer join entreprise entreprise5_ on contact3_.entreprise_id=entreprise5_.id left outer join adresse adresse6_ on entreprise5_.adresse_id=adresse6_.id left outer join entreprise entreprise7_ on this_.entreprise_id=entreprise7_.id
