Can't use := for variable assignment within a SQL-Statement
-----------------------------------------------------------
Key: HHH-2697
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2697
Project: Hibernate3
Issue Type: Bug
Affects Versions: 3.2.4.sp1
Environment: MySQL Datasource, Hibernate 3.2.4.sp1
Reporter: Benjamin Gniza
Priority: Minor
i found a kind of bug in org.hibernate.engine.query.ParameterParser.java:
I have an exotic mysql-statement where I want to use mysql variables.
VERY SIMPLE example:
SET @pos=0;
SELECT @pos:=@pos+1 FROM TABLE;
Steps to reproduce:
Session s = sessionFactory.openSession();
s.createSQLQuery("SET @pos=0").executeUpdate();
SQLQuery qry = s.createSQLQuery("select @pos:=@pos from SomeTable");
List lst = qry.list();
Exception:
org.hibernate.QueryException: Space is not allowed after parameter prefix ':' 'SELECT @pos:=@pos+1 FROM TABLE'
at org.hibernate.engine.query.ParameterParser.parse(ParameterParser.java:68)
...
...
Suggested fix:
ParameterParser Lines 62 to 73:
if (c == ':' && (indx + 1 >= stringLength || sqlString.charAt(indx + 1) != '=')) {
// named parameter
int right = StringHelper.firstIndexOfChar( sqlString, ParserHelper.HQL_SEPARATORS, indx + 1 );
int chopLocation = right < 0 ? sqlString.length() : right;
String param = sqlString.substring( indx + 1, chopLocation );
if ( StringHelper.isEmpty( param ) ) {
throw new QueryException("Space is not allowed after parameter prefix ':' '"
+ sqlString + "'");
}
recognizer.namedParameter( param, indx );
indx = chopLocation - 1;
}

[Hibernate-JIRA] Created: (HHH-2318) Sometimes wrong classloader used for proxy interfaces
by Jan Wiemer (JIRA)
Sometimes wrong classloader used for proxy interfaces
-----------------------------------------------------
Key: HHH-2318
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2318
Project: Hibernate3
Type: Bug
Components: core
Versions: 3.2.1
Reporter: Jan Wiemer
For some of our business classes we used a Mapping declaring the class to be lazy initialized and providing a proxy interface like e.g.:
<class name="TestClassImpl" proxy="TestClass" table="testTable" lazy="true"> ... </class>
Using classes mapped this way - e.g. as endpoint of a one to one relation - sporadically leads to exceptions like the following:
org.hibernate.PropertyAccessException: IllegalArgumentException occurred while calling setter of test.AbstractTestClass2Impl.testField
at org.hibernate.property.BasicPropertyAccessor$BasicSetter.set(BasicPropertyAccessor.java:104)
at org.hibernate.tuple.entity.AbstractEntityTuplizer.setPropertyValues(AbstractEntityTuplizer.java:337)

at org.hibernate.impl.QueryImpl.list(QueryImpl.java:79)
at org.hibernate.impl.AbstractQueryImpl.uniqueResult(AbstractQueryImpl.java:804)
Note that the application is residing in a different classloader than hibernate (and CGLIB...).
Examining the situation we see that the value passed to the setter was a CGLIB proxy. Internally the proxy stores an array of interfaces the proxy should implement. In our situation this interface contains the HibernateProxy interface and our business interface provided as proxy interface in the mapping. In this interface array we checked the classloader of the interfaces. As expected the HibernateProxy interface is loaded by the system classloader and our interface was loaded by our custom classloader. However examining the actual interfaces of the proxy (with proxy.getClass().getInterfaces()[i].getClassLoader() for all i) shows that all interfaces are loaded with the system classloader. This causes the exception above.
Doing some more experiments we experience that the problem does not occur all the time. Sometimes the actual proxy interfaces are as expected (the HibernateProxy interface is loaded by the system classloader and our interface was loaded by our custom classloader). We notice that each time the test failed the HibernateProxy was the first interface in the interface array stored in the proxy.
Some experiments with the CGLIB (the Enhancer class) shows us that (if there is no superclass given) they use the classloader of the first passed interface as default classloader (compare method net.sf.cglib.proxy.Enhancer.getDefaultClassLoader()).
Finally we find out that hibernate passes the proxy interfaces in an arbitrary order since they are using a HashSet for the proxy interfaces in the method org.hibernate.tuple.entity.PojoEntityTuplizer.buildProxyFactory(PersistentClass persistentClass, Getter idGetter, Setter idSetter). This Hash set is passed to the method org.hibernate.proxy.pojo.cglib.CGLIB_ProxyFactory.postInstantiate(...). There it is simply converted to an Array (leading to a randomized order).
As a workaround it is possible to patch the class org.hibernate.proxy.pojo.cglib.CGLIB_ProxyFactory and add reorganize the array if the HibernateProxy interface is the first one:
this.interfaces = (Class[]) interfaces.toArray(NO_CLASSES);
//----->PATCH<--------
if(this.interfaces.length > 1) {
Class firstIfc = this.interfaces[0];
if(firstIfc.getName().startsWith("org.hibernate")) {
this.interfaces[0] = this.interfaces[1];
this.interfaces[1] = firstIfc;
System.err.println("Replace: " + firstIfc.getName() + " by " + this.interfaces[0].getName());
}
}
//--------------------
After applying this patch everything woks as expected.

@OrderBy usage on a joined classes (when using join table) produces incorred SQL syntax.
----------------------------------------------------------------------------------------

Project: Hibernate Annotations
Issue Type: Bug
Affects Versions: 3.3.0.ga

Please consider the following mapping :
@ManyToMany(cascade = {CascadeType.PERSIST, CascadeType.MERGE}, fetch = FetchType.LAZY)
@IndexColumn(name = "ListIndex")

public abstract class RoutingManipulationComponent extends RoutingComponent implements Initializable {
/**
* Applies the manipulation to the given context.
*
* @param context the routing context to manipulate
* @return true if any manipulation was applied, false if no manipulation
* occurred
*/
public abstract boolean apply(RoutingContext context);
}
******************************************
@Entity(name = "RoutingComponent")

*******************************
@MappedSuperclass
@Cache(usage = CacheConcurrencyStrategy.READ_WRITE)
public abstract class DialPlanProvisionalEntity extends ProvisionalEntity
implements Initializable {
private Long entityId;
private boolean visible = true;
private int priority;
/**

@Deprecated
public DialPlanProvisionalEntity() {

}
/**

public DialPlanProvisionalEntity(String name, String description) {

}
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Override
public Long getId() {
return entityId;
}
@Override
public void setId(Long ruleCollectionId) {
this.entityId = ruleCollectionId;
}
/**

*/
public int getPriority() {

}
@Override

return false;
}
final ProvisionalEntity other = (ProvisionalEntity) o;
return MiscUtils.equalOrBothNull(this.getName(), other.getName());
}
@Override
public int hashCode() {
String name = this.getName();
return getClass().getName().hashCode() + 13 * name.hashCode();
}
}
The above mapping should use the "priority" field to the ordering.
SQL that is produced is :
select criteria0_.RoutingRuleId as RoutingR1_1_, criteria0_.CriteriaComponentId as Criteria2_1_,
criteria0_.ListIndex as ListIndex1_,
routingcri1_.id as id73_0_,
routingcri1_.creationDate as creation3_73_0_,
routingcri1_.description as descript4_73_0_,
routingcri1_.lastModificationDate as lastModi5_73_0_,
routingcri1_.name as name73_0_,
routingcri1_.predefined as predefined73_0_,
routingcri1_.status as status73_0_,
routingcri1_.priority as priority73_0_,
routingcri1_.visible as visible73_0_,
routingcri1_.matcher_id as matcher25_73_0_,
routingcri1_.criterion_id as criterion27_73_0_,
routingcri1_.location_id aslocation26_73_0_,
routingcri1_.RoutingComponentType as RoutingC1_73_0_
from odp_rulecriteriajoin criteria0_
left outer join odp_routingcomponent as routingcri1_ on criteria0_.CriteriaComponentId=routingcri1_.id
where criteria0_.RoutingRuleId=1 order by odp_routingcomponent .priority asc
It is wrong since not the table alias is used in the order by clause, but the real table name.
Mysql fails with exception that odp_rulecriteriajoin.priority is unknown table.
Changing the query to include "order by criteria0_.priority asc" returns the correct result.

incorrect hql query on one-to-one with property-ref
----------------------------------------------------
Key: HHH-2158
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2158
Project: Hibernate3
Type: Bug
Components: core
Versions: 3.2.0.ga
Environment: hibernate 3.2.0.ga with firebird 1.5.3 and jaybird 1.5.5 driver on windows XP
Reporter: Sebastien Cesbron
Attachments: testhib.zip
I have a one-to-one relationship with property-ref between Master and Slave2.
I want to find all Master instances that have a null Slave2 instance associated.
To do so my query is
select master from Master master where master.slave2 is null
The sql generated is
select master0_.oid as oid0_, master0_.libelle as libelle0_ from Master master0_ where master0_.oid is null
which seems incorrect. It checks here Master instances with null id (config files are listed below).
If I do my query like this
select master from Master master where master.slave2.oid is null
the generated sql is ok :
select master0_.oid as oid0_, master0_.libelle as libelle0_ from Master master0_, Slave2 slave2x1_ where master0_.oid=slave2x1_.myMaster and (slave2x1_.oid is null)
I have attached a small eclipse project that reproduces the problem
This problem may-be related to the one I have submitted as issue HHH-1849
