@OrderBy don't quote identifiers
--------------------------------
Key: ANN-807
URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-807
Project: Hibernate Annotations
Issue Type: Bug
Affects Versions: 3.4.0.GA
Environment: Hibernate 3.3.1.GA, MS SQL Server 2000
Reporter: StarBreeze
@OrderBy annotation ignoring quote identifiers.
Test case.
1. Mapping class:
import java.io.Serializable;
import java.util.List;
import javax.persistence.*;
@Entity
@Table(name = "Category")
public class Category implements Serializable {
private static final long serialVersionUID = 1L;
private Integer id;
private String name;
private Integer order;
private Category parent;
private List<Category> children;
@Id
@Column(name = "CategoryId")
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
@Column(name = "Name")
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
@Column(name = "`Order`")
public Integer getOrder() {
return order;
}
public void setOrder(Integer order) {
this.order = order;
}
@ManyToOne()
@JoinColumn(name = "ParentCategoryId")
public Category getParent() {
return parent;
}
public void setParent(Category parent) {
this.parent = parent;
}
@OneToMany(cascade = CascadeType.ALL, mappedBy = "parent", fetch = FetchType.EAGER)
@OrderBy("order")
public List<Category> getChildren() {
return children;
}
public void setChildren(List<Category> children) {
this.children = children;
}
}
2. Fetch code:
Criteria criteria = getSession().createCriteria(Category.class);
criteria.add(Restrictions.eq("name", "Indexes"));
Category category = (Category) criteria.uniqueResult();
Hibernate generates correct select part with wrong "order by":
select this_.CategoryId as CategoryId1_1_, this_.Name as Name1_1_, this_.[Order] as Order3_1_1_, this_.ParentCategoryId as ParentCa4_1_1_, children2_.ParentCategoryId as ParentCa4_3_, children2_.CategoryId as CategoryId3_, children2_.CategoryId as CategoryId1_0_, children2_.Name as Name1_0_, children2_.[Order] as Order3_1_0_, children2_.ParentCategoryId as ParentCa4_1_0_ from Category this_ left outer join Category children2_ on this_.CategoryId=children2_.ParentCategoryId where this_.Name=? order by Order asc

[Hibernate-JIRA] Created: (HHH-3300) HQL looks for property in wrong class and reports "could not resolve property"

HQL looks for property in wrong class and reports "could not resolve property"
------------------------------------------------------------------------------
Key: HHH-3300
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3300
Project: Hibernate3
Issue Type: Bug
Components: query-hql
Affects Versions: 3.2.6
Environment: Hibernate 3.2.6.ga, mysql 5.0.37
Reporter: Cristian Bogdan
could not resolve property: groupMembers of: projman.Project
[SELECT it.project.color AS col1 FROM projman.Deficienta def JOIN def.item it WHERE exists (FROM it.project.participants grp JOIN grp.groupMembers p WHERE p=:principal )
)) ORDER BY it.end]
the problem is, groupMembers is not a property of projman.Project, but a bag in projman,Principal.
as soon as I replace the it.project.color projection with e.g. it.start (i.e. i don't make any other join with projman.Project), the query works.
the original query is actually more complicated but i reduced my test to the above for simplicity. rewriting the query without subqueries is not an option.
i paste the relevant (generated) mappings.

[Hibernate-JIRA] Created: (EJB-363) @OrderBy applied to collection property of derived class does not work properly when column used for ordering belongs to base class (using MySQL 5)
by Rich Eggert (JIRA)
@OrderBy applied to collection property of derived class does not work properly when column used for ordering belongs to base class (using MySQL 5)
---------------------------------------------------------------------------------------------------------------------------------------------------
Key: EJB-363
URL: http://opensource.atlassian.com/projects/hibernate/browse/EJB-363
Project: Hibernate Entity Manager
Issue Type: Bug
Components: EntityManager
Affects Versions: 3.3.2.GA
Environment: MySQL 5.0.18, Hibernate Core 3.2.6, Hibernate EntityManager 3.3.2, and the MySQL5InnoDBDialect.
Test run with Tomcat 6.0.16 (Sun JDK 1.6.0_06) and Spring Framework 2.5.3.
Relying on Hibernate automatic DDL generation (hibernate.hbm2ddl.auto=update), which appears to be working properly.
Reporter: Rich Eggert
Attachments: SampleBase.java, SampleDerived.java, SampleServiceImpl.java
I applied the (JPA) @OrderBy annotation to a collection of entities belonging to an entity class (named SampleDerived in the attached sample code) of the same type (i.e., the class has a one-to-many parent-child relationship to itself). The property name passed as the argument to the @OrderBy annotation refers to a property of the base class (named SampleBase in the example), which employs the "JOINED" inheritence strategy.
When I attempted to access the collection of a persisted instance of the entity class (in the example, this is accomplished by calling SampleServiceImpl.createSample() followed by calling SampleServiceImpl.findChildren() against the return value), the following (root cause) exception is generated:

I verified (using MySQL Administrator) that the SampleBase.timestamp column does, in fact, exist. According to the org.hibernate.SQL log, the offending SQL statement looks like this:
select children0_.parent_id as parent2_1_, children0_.id as id1_, children0_.id as id5_0_, children0_1_.timestamp as timestamp5_0_, children0_.parent_id as parent2_6_0_ from SampleDerived children0_ inner join SampleBase children0_1_ on children0_.id=children0_1_.id where children0_.parent_id=? order by SampleBase.timestamp asc
I believe the problem is that MySQL 5 requires that the alias for the base class table used in the FROM clause (children0_1_ in this case) be used in the ORDER BY clause, instead of the actual name of the base class table. After browsing various MySQL discussions, it appears this is new to MySQL 5 (versus 4 or earlier) and was done in order to be more standards compliant.
It's unclear to me whether this affects Hibernate Core or is limited to EntityManager. I'll try to narrow down the problem further as time permits (which it isn't likely to do any time soon).

[Hibernate-JIRA] Created: (HHH-3577) Wrong SQL in order by clause when using joined subclasses
by Hardy Ferentschik (JIRA)
Wrong SQL in order by clause when using joined subclasses
---------------------------------------------------------
Key: HHH-3577
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3577
Project: Hibernate Core
Issue Type: Bug
Components: core
Reporter: Hardy Ferentschik
Assignee: Steve Ebersole
The changes for HHH-2802 seem to have broken the following tests in Annotations:
* ManyToManyTest.testOrderByContractor()
* OneToManyTest.testOrderByOnSuperclassProperty()
Prior to the changes for HHH-2802 no table aliases where generated for in the SQL for these tests. Since it is generally a problem to generate the right table alias in case of joined subclasses there is a workaround in CollectionBinder.buildOrderByClauseFromHql() line 910 where the table name is explicitly set in the oder by clause. This workaround together with the changes for HHH-2802 now generate illegal SQL, eg:
select
contractor0_.EMPLOYER_ID as EMPLOYER1_1_,
contractor0_.CONTRACTOR_ID as CONTRACTOR2_1_,
contractor1_.id as id2_0_,
contractor1_1_.fld_name as fld2_2_0_,
contractor1_.hourlyRate as hourlyRate3_0_
from
EMPLOYER_CONTRACTOR contractor0_
left outer join
Contractor contractor1_
on contractor0_.CONTRACTOR_ID=contractor1_.id
left outer join
Employee contractor1_1_
on contractor1_.id=contractor1_1_.id
where
contractor0_.EMPLOYER_ID=?
order by
contractor1_.Employee.fld_name desc
Hibernate:
select
contractor0_.EMPLOYER_ID as EMPLOYER1_1_,
contractor0_.CONTRACTOR_ID as CONTRACTOR2_1_,
contractor1_.id as id2_0_,
contractor1_1_.fld_name as fld2_2_0_,
contractor1_.hourlyRate as hourlyRate3_0_
from
EMPLOYER_CONTRACTOR contractor0_
left outer join
Contractor contractor1_
on contractor0_.CONTRACTOR_ID=contractor1_.id
left outer join
Employee contractor1_1_
on contractor1_.id=contractor1_1_.id
where
contractor0_.EMPLOYER_ID=?
order by
contractor1_.Employee.fld_name desc
In this case 'contractor1_' is generated by the changes made for HHH-2802 whereas 'Employee' is added by the workaround. Note that even though Employee is not working for all databases, the generated alias is wrong and should be 'contractor1_1_.
For now I commented out the failing tests since I cannot use the test skipping functionality in Annotations yet.

ejbql select count() and composite keys problem

Reporter: Thierry Accart
Priority: Critical
Hi
we're using seam 2.1.2 on JBoss 4.2.2 with JDK 1.5.18.
Our db is hosted on mssql server.
our persistence.xml contains sets hibernate.dialect to org.hibernate.dialect.SQLServerDialect.
UserRole is an entity containing userid and roleid as a composite key.
When the following ejbql query is run :
select count(userRole) from UserRole userRole
sql receives the following statement :
declare @P1 int
set @P1=NULL
declare @P2 int
set @P2=0
declare @P3 int
set @P3=0
exec sp_cursorprepexec @P1 output, @P2 output, NULL, N'select count((userrole0_.roleId, userrole0_.userId)) as col_0_0_ from TP_UM_UserRole userrole0_', 16, 8193, @P3 output
select @P1, @P2, @P3
the count((userrole0_.roleId, userrole0_.userId)) is not understood by mssql server, causing an error " Incorrect syntax near ','."
I think that a simple select count (*) would work fine.
