THIS_"."NAME": invalid identifier when using createCriteria with addOrder
-------------------------------------------------------------------------
Key: HHH-2847
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2847
Project: Hibernate3
Issue Type: Bug
Components: query-criteria
Affects Versions: 3.0.5
Environment: Oracle - 10.2.0
Reporter: Ashish Tiwari
We are using hibernate 3.0.5 and once a while I see following error getting generated due to incorrect SQL generated by hibernate:
Hibernate: select systembean0_.SYSTEMID as SYSTEMID12_0_, systembean0_.Version as Version12_0_, systembean0_.NAME as NAME12_0_, systembean0_.TYPE as TYPE12_0_, systembean0_.DESCRIPTION as DESCRIPT5_12_0_ from SDSYSTEM systembean0_ order by this_.NAME asc
- SQL Error: 904, SQLState: 42000
- ORA-00904: "THIS_"."NAME": invalid identifier
This normally works but occasionally we run into the issue mentioned above. I do not see alias "this_" in the sql query and I think that causes the error to happen. Issue is caused by alias not used consistently.
In normal case the generated SQL looks like following:
Hibernate: select this_.SYSTEMID as SYSTEMID7_0_, this_.Version as Version7_0_, this_.NAME as NAME7_0_, this_.TYPE as TYPE7_0_, this_.DESCRIPTION as DESCRIPT5_7_0_ from SDSYSTEM this_ order by this_.NAME asc
I am not sure what causes this problem. Has anyone else see similar problem earlier?
I appreciate any help with this. Below is other information:

Generated version are incremented by Hibernate
----------------------------------------------
Key: HHH-2796
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2796

Issue Type: Bug
Components: core
Affects Versions: 3.2.1
Environment: 3.2.1, Oracle 10g
Reporter: Heba Tawfik
Creating a new entity which it's version is set to generated="always" & saving it, then in the same session adding an object to any of its on-to-many relationships is throwing a StaleObjectStateException.
To regenerate the problem, consider the following code
1- departement.hbm.xml :
----------------------------------------
<hibernate-mapping package="com.myproject.domain">
<class name="Departement" table="Departement">
<id name="id">
<column name="dept_id" />
</id>
<version column="version" generated="always" name="version" type="integer" unsaved-value="null" />
<property name="name" column="name" />
<bag name="employees" inverse="true" cascade="all" lazy="true">
<key column="dept_id"></key>
<one-to-many class="Employee" />
</bag>
</class>
</hibernate-mapping>
2- employee.hbm.xml :
--------------------------------------
<hibernate-mapping package="com.myproject.domain">
<class name="Employee" table="Employee">
<id name="id">
<column name="employee_id" />
</id>

</class>
</hibernate-mapping>
3- Departement.Java
---------------------------
package com.myproject.domain;
import java.util.ArrayList;
import java.util.List;
public class Departement extends BaseDepartement{
int id;
String name;
List employees;
Integer version;
public int getId() {

}
public void setName(String name) {
this.name = name;
}
public Integer getVersion() {

this.employees = employees;
}
public void addToEmployeeList(Employee emp)
{
if(employees==null)
{
setEmployees(new ArrayList());

4- Code To Test :
------------------------
public static void main(String args[]) throws Exception
{
SessionFactory factory = new Configuration().configure("com/myproject/config/hibernate.cfg.xml").buildSessionFactory();
Session session = factory.openSession();
Transaction transaction = session.beginTransaction();
Departement aDept =new Departement();
aDept.setId(10);
aDept.setName("Test");
session.save(aDept);
transaction.commit();
transaction = session.beginTransaction();
Employee emp=new Employee();
emp.setId(10);
emp.setFirstName("test");
emp.setLastName("test");
emp.setSalary(10);
emp.setAge(10);
emp.setDepartment(aDept);
aDept.addToEmployeeList(emp);
session.saveOrUpdate(aDept);
transaction.commit();
session.close();
}
On the database, the default value for version cloumn is set to "1" and a trigger is defined as follow on the Departement table:
create or replace
TRIGGER TRIGGER1
BEFORE UPDATE ON DEPARTEMENT
FOR EACH ROW
BEGIN
:new.version:= :old.version + 1;
END;
Upon executing the above code, the following is the hibernate logging :

[Hibernate-JIRA] Created: (HHH-2776) Restrictons.in(..) generates invalid SQL if list of values is empty

Restrictons.in(..) generates invalid SQL if list of values is empty
-------------------------------------------------------------------
Key: HHH-2776
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2776
Project: Hibernate3
Issue Type: Bug
Components: query-criteria
Affects Versions: 3.2.2
Environment: Hibernate 3.2.2.ga, MySQL 4.1.18, Windows XP
Reporter: Adrian Smith
I have classes called A and B. There is a 1:n relationship from A to B.
Class B has the following in its mapping file:
<many-to-one name="a" class="A" column="fk_a_id" not-null="true" />
If I write the following code:
List<B> foo() {
List<A> aList = ....
Session session = ....
Criteria query = session.createCriteria(B.class);
query.add(Restrictions.in("a", aList));
return query.list();
}
Then all works fine and the results I want are returned. However, if aList is empty (i.e. aList.size()==0) then the query.list function generates and executes invalid SQL for MySQL.
java.sql.SQLException: Syntax error or access violation message from server: "You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ')' at line 1"
I imagine that it is generating SQL like IN () which isn't valid.
I realize it's a bit ridiculous to want to find the rows where a field is IN the empty list. Nothing will ever be returned. However, in my opinion it should still be allowed, and return no rows, just as saying "WHERE 1=2" is allowed, just doesn't return any rows.

[Hibernate-JIRA] Created: (HHH-2831) Native SQL queries with addJoin or <return-join/> return object arrays instead of single Entities
by Jeremy Grodberg (JIRA)
Native SQL queries with addJoin or <return-join/> return object arrays instead of single Entities
-------------------------------------------------------------------------------------------------
Key: HHH-2831
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2831
Project: Hibernate3
Issue Type: Bug
Components: query-sql
Affects Versions: 3.2.5, 3.2.4
Environment: Hibernate 3.2.4.ga and 3.2.5.ga with hsqldb on Win XP
Reporter: Jeremy Grodberg
Attachments: NativeSQLQueriesTest.patch
Although the documentation is not crystal clear, I read it to say that using addJoin should eagerly fetch an associated object but should NOT return it as a separate value. In section 16.1.3. "Handling associations and collections" of the online documentation it says: "It is possible to eagerly join in the Dog to avoid the possible extra roundtrip for initializing the proxy. This is done via the addJoin() method, which allows you to join in an association or collection." This comes BEFORE the section on returning multiple entities, so I say the documentation at least implies it will only return a single entity at the top level. Also, if the intention is to return multiple entities, addEntity() works fine for that, so what then would be the difference of addJoin()? If I'm wrong about what addJoin() should do, please clarify that in the documentation and also clarify how, if it is possible, one could eagerly fetch the association without changing the return type of the quer
y.
I have reproduced this problem in the Hibernate JUnit tests in 3.2.4.ga and 3.2.5.ga, specifically NativeSQLQueriesTest.testSQLQueryInterface().
I'm attaching a patch to the Hibernate junit test org.hibernate.test.sql.hand.query.NativeSQLQueriesTest.java released in 3.2.5.ga that adds a test to ensure that a query with addJoin only returns a (list of) entities, not a list of Object arrays containing entities. Currently, the assertion fails because instead of returning a list of Organizations we get a list of Object[3] = { Organization, Employment, Person }, which is exactly what we get when the addJoin()s are replaced with appropriate addEntity() calls.

</query>
</hibernate-mapping>
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
test.hibernate.User and test.hibernate.Group classes are just simple beans.
In Group.hbm.xml there is a query called "Group.select.by.login", it's intended to be cached. So I add corresponding properties to Hibernate configuraition:
--------------------------------------------------------------------------------------------------
properties.put("hibernate.cache.provider_class", "org.hibernate.cache.EhCacheProvider");
properties.put("hibernate.cache.use_query_cache", "true");
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Configuration has no extra parameters.
Then I'm trying to execute the query two times:
-------------------------------------------------------------------------------------------------- test fragment
SessionFactory sessionFactory = configuration.buildSessionFactory();
Session session = null;
try {
session = sessionFactory.openSession();
Query query = session.getNamedQuery("Group.select.by.login");
List<Group> groups;
groups = query.setParameter(0, "admin").list(); // +++++++++++++++This list() returns list of two Group objects, ok +++++++++++++++
System.out.println("-----------------------------------------------------------------------------------");
for (Group group : groups) {
System.out.println(group.getName());
}
System.out.println("-----------------------------------------------------------------------------------");
groups = query.setParameter(0, "admin").list(); // +++++++++++++++This list() returns list of two nulls +++++++++++++++
System.out.println("-----------------------------------------------------------------------------------");
for (Group group : groups) {
System.out.println(group.getName());
}
System.out.println("-----------------------------------------------------------------------------------");
} finally {
if (session != null) {
session.close();
}
sessionFactory.close();
}
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
The first query returns list of, in my case, two groups. The second query returns list of two nulls instead of the same list.
I've investigated the problem, and found the following:
Query return value is "user.groups", and during query analysis (org.hibernate.hql.ast.QueryTranslatorImpl:160) query return type is defined as "org.hibernate.type.BagType(test.hibernate.User.groups)". This seems to be the problem, as during query put operation org.hibernate.CollectionType.disassemble is called (org.hibernate.cache.StandardQueryCache:80), which simply returns null as owner is null.
If this query is not a misuse, then I think, something is to be done at the time of analysis, so that return type be somewhat different.
Thanks.
