Repeated column chack fails with SingleTable inheritance, biut not with TablePerClass

Type: Bug

Not sure about component.
Parent class introduce field, which is also discriminator field.
Hibernate reports error in child class if and only if strategy = InheritanceType.SINGLE_TABLE

[Hibernate-JIRA] Created: (HHH-2733) .executeUpdate() Wrong SQL translation

.executeUpdate() Wrong SQL translation
---------------------------------------
Key: HHH-2733
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2733
Project: Hibernate3
Issue Type: Bug
Components: core
Environment: hibernate3
Reporter: Giuseppe Manara
I set :
Query myQuery = mySession.createQuery("update antiric.elaborazioni.model.ArcuniA aa set aa.aunCanDes = (select distinct can.canDes from antiric.tabelle.model.TabCan can, antiric.tabelle.model.TabCsi csi where can.idCanCsi=csi.id and can.canCod=aa.aunTcan and csi.csiCod=aa.aunTcsi) where aa.aunCanDes is null and aa.aunTipSta=1");
...
When I do :
myQuery.executeUpdate();
I get
org.hibernate.exception.SQLGrammarException: could not execute update query
org.postgresql.util.PSQLException: ERROR: column reference "id" is ambiguous !!!!!!
the sql property of the SQLGrammarException is:
"update ARCUNIA set aunCanDes=(select distinct tabcan1_.canDes from TABCAN tabcan1_, TABCSI tabcsi2_ where idCanCsi=id and canCod=aunTcan and csiCod=aunTcsi) where (aunCanDes is null) and aunTipSta=?"
... as you can see,
my original " .. can.idCanCsi=csi.id .." is converted into ".. idCanCsi=id .." and that's why the error
P.S.:
nothing to do with the JOIN .. ON clause ; it seems not supported from .createQuery("..")
best reguards,
giuseppe

[Hibernate-JIRA] Created: (HHH-2714) Three typos in code examples
by Jan Hustak (JIRA)
Three typos in code examples
----------------------------
Key: HHH-2714
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2714
Project: Hibernate3
Issue Type: Bug
Components: documentation
Affects Versions: 3.2.4.sp1
Reporter: Jan Hustak
Priority: Trivial
Attachments: hibernate-docs.patch
I have found a few apparent typos in code examples in the documentation:
- in section 6.3.2. "Bidirectional associations":
<class name="Item">
<id name="id" column="CATEGORY_ID"/>
should probably be
<class name="Item">
<id name="id" column="ITEM_ID"/>
- in section 10.4.1.2 "Queries that return tuples":
Object[] tuple = (Object[]) kittensAndMothers.next();
Cat kitten = tuple[0];
Cat mother = tuple[1];
should probably be
Object[] tuple = (Object[]) kittensAndMothers.next();
Cat kitten = (Cat) tuple[0];
Cat mother = (Cat) tuple[1];
- in section 11.3.2 "Application version checking":
if ( oldVersion!=foo.getVersion ) throw new StaleObjectStateException();
should probably be
if ( oldVersion != foo.getVersion() ) throw new StaleObjectStateException();
I've attached a patch that takes care of these; it was done against CVS earlier today.

[Hibernate-JIRA] Created: (ANN-635) Hib doesn't share allocated sequence values between different classes
by Adam Wozniak (JIRA)
Hib doesn't share allocated sequence values between different classes
---------------------------------------------------------------------
Key: ANN-635
URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-635
Project: Hibernate Annotations
Issue Type: Improvement
Affects Versions: 3.3.0.ga
Reporter: Adam Wozniak
Attachments: Zbbb.java, Zccc.java
Hello Everybody
This is my first issue here, so I don't know if my issue will be classified as a bug or an improvement only.
My config:
hibernate-3.2.4.sp1
hibernate-annotations-3.3.0.GA
hibernate-entitymanager-3.3.1.GA
I use Oracle database. I have 2 entity classes (Zbbb and Zccc).
Those 2 classes map two database table: ZBBB and ZCCC.
Both tables have identical structure:
ID - NUMBER (primary key)
TEXT - VARCHAR2(10)
Identifiers for both tables are generated by _ONE_ (the same) Oracle sequence.
For both entities I have following annotations:
@Id
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "my_generator")
@javax.persistence.SequenceGenerator(
name = "my_generator"
, sequenceName = "SEQ_DEPT"
, allocationSize=2)
Note, that allocationSize is set: 2.
When I am creating and persisting 2 Zbbb and 2 Zccc entities like this:
{ Zccc entity = new Zccc(); em.persist(entity); } // DB HIT!
{ Zccc entity = new Zccc(); em.persist(entity); }
{ Zbbb entity = new Zbbb(); em.persist(entity); } // DB HIT!
{ Zbbb entity = new Zbbb(); em.persist(entity); }
... everything is OK because I have 2 hits to database sequence only.
But when I am creating and persisting 1 Zbbb and 3 Zccc entities like this:
{ Zbbb entity = new Zbbb(); em.persist(entity); }
{ Zccc entity = new Zccc(); em.persist(entity); }
{ Zccc entity = new Zccc(); em.persist(entity); }
{ Zccc entity = new Zccc(); em.persist(entity); }
... I have 3 hits do database sequence.
I would expect, that Hibernate should recognize that Zbbb and Zccc are suing the same database sequence and should share all cached values between entities of those two classes.
Do I do something wrong?
Kind regards,
Adam Wozniak
