EntityManager.createQuery does not recognize COUNT CASE statement
-----------------------------------------------------------------
Key: EJB-376
URL: http://opensource.atlassian.com/projects/hibernate/browse/EJB-376
Project: Hibernate Entity Manager
Issue Type: Bug
Components: EntityManager
Affects Versions: 3.4.0.CR2, 3.3.1.GA
Environment: Tested with both Hibernate 3.2.5.ga and Hibernate 3.3.0.CR2, Postgres 8.1, Postgres 8.2, Linux Ubuntu.
Reporter: Mark Plutowski
I searched the Hibernate forums and did not find mention of this issue or one that was closely related. I also posted this to the Hibernate Users forum, and did not receive any replies recognizing the bug or stating that it has been resolved or has a workaround.
To summarize, EntityManager.createQuery does not recognize SQL related to applying a COUNT to a CASE, whereas it does correctly run SQL that applies a SUM to a CASE. More detail follows.
--- Summary Overview ---
EntityManager.createQuery runs a SELECT query containing the following HQL/JQL snippet runs correctly:
" SUM ( CASE WHEN (cs.serveTs BETWEEN :beginTs AND :endTs ) THEN 1 ELSE 0 END ) "
However, the following do not work:
" COUNT ( DISTINCT CASE WHEN (cs.serveTs BETWEEN :beginTs AND :endTs ) THEN cs.componentId ELSE NULL END ) "
" COUNT ( DISTINCT (CASE WHEN (cs.serveTs BETWEEN :beginTs AND :endTs ) THEN cs.componentId ELSE NULL END ) ) "
" COUNT ( CASE WHEN (cs.serveTs BETWEEN :beginTs AND :endTs ) THEN cs.componentId ELSE NULL END ) "
The first two statements run and return correct results when translated to SQL and run against the Postgresql database in PgAdmin.
Here's the exception thrown when using COUNT ( DISTINCT CASE WHEN
101976 [main] ERROR org.hibernate.hql.PARSER - line 1:93: unexpected token: CASE
101977 [main] ERROR org.hibernate.hql.PARSER - line 1:98: unexpected token: WHEN
Here's the exception thrown when the extra parenthesis is added to give COUNT ( DISTINCT (CASE WHEN
85587 [main] ERROR org.hibernate.hql.PARSER - line 1:93: unexpected token: (
85588 [main] ERROR org.hibernate.hql.PARSER - line 1:99: unexpected token: WHEN
--- Additional Detail ---
Here is the complete SQL for the COUNT (DISTINCT (CASE use case:
String queryString = "Select c.id.pubId, c.id.clipId, c.duration, " +
"count(distinct s.slotId) , " +
" COUNT ( DISTINCT (CASE WHEN (cs.serveTs BETWEEN :beginTs AND :endTs ) THEN cs.componentId ELSE NULL END ) ) " +
"from CmClip c " +
"join c.cmClipSlots s " +
"left outer join c.csComponents cs " +
"where (s.adSizeX * c.width) >= :adWidth " +
"and (s.adSizeY * c.height) >= :adHeight " +
"and (c.isQaDone = true or c.isQaDone is null) " +
"and c.isEnabled = true " +
"group by c.id.pubId, c.id.clipId, c.duration " +
"order by " + orderByCol;
This results in the following exception:
85587 [main] ERROR org.hibernate.hql.PARSER - line 1:93: unexpected token: (
85588 [main] ERROR org.hibernate.hql.PARSER - line 1:99: unexpected token: WHEN
Here is the SQL for the SUM CASE sql snippet that does run and return correct results:
String queryString = "Select c.id.pubId, c.id.clipId, c.duration, " +
"count(distinct s.slotId) , " +
" SUM ( CASE WHEN (cs.serveTs BETWEEN :beginTs AND :endTs ) THEN 1 ELSE 0 END ) " +
"from CmClip c " +
"join c.cmClipSlots s " +
"left outer join c.csComponents cs " +
"where (s.adSizeX * c.width) >= :adWidth " +
"and (s.adSizeY * c.height) >= :adHeight " +
"and (c.isQaDone = true or c.isQaDone is null) " +
"and c.isEnabled = true " +
"group by c.id.pubId, c.id.clipId, c.duration " +
"order by " + orderByCol;
Here is the code snippet that performs the transaction:
float roFactor = (float) 0.5;
transactionMgr.begin();
List<Object[]> result = entityMgr.createQuery(queryString)
.setParameter("adWidth", (widthF-roFactor)).
setParameter("adHeight", (heightF-roFactor))
.setParameter("beginTs", beginTs, javax.persistence.TemporalType.TIMESTAMP)
.setParameter("endTs", endTs, javax.persistence.TemporalType.TIMESTAMP)
.getResultList();
transactionMgr.commit();
The fact that "SUM (CASE" is parsed and run correctly, whereas "COUNT (CASE" throws an exception seems to indicate a bug. I replicated this using both (Hibernate 3.2.5.ga with EntityManager 3.3.1.GA) and (Hibernate 3.3.0.CR2 with EntityManager 3.4.0.CR2).

[Hibernate-JIRA] Created: (HHH-2951) Restrictions.eq when passed null, should create a NullRestriction
by David Sheldon (JIRA)
Restrictions.eq when passed null, should create a NullRestriction
-----------------------------------------------------------------
Key: HHH-2951
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2951
Project: Hibernate3
Issue Type: Improvement
Components: query-criteria
Affects Versions: 3.2.1
Reporter: David Sheldon
Priority: Trivial
If you create a Restriction using eq, and pass null to it, then the generated SQL is "where foo = null", which always returns false.
The programmer will almost certainly have intended to get "where foo is null".
Ideally, we could change:
public static SimpleExpression eq(String propertyName, Object value) {
return new SimpleExpression(propertyName, value, "=");
}
to
public static SimpleExpression eq(String propertyName, Object value) {
if (value == null) {
return isNull(propertyName);
}
else {
return new SimpleExpression(propertyName, value, "=");
}
}
Unforunately that wont work, as isNull doesn't return a SimpleExpression.

See the forum posting http://forum.hibernate.org/viewtopic.php?p=2403045 for another description of this problem. That thread suggests the problem is with EJB3OverridenAnnotationReader not adding properties annotated with @JoinColumn if xml mapping files exist.
My code is:
@Any(metaColumn = @Column(name = "RelatedRecType"))
@AnyMetaDef(idType = "integer", metaType = "string", metaValues = {
@MetaValue(targetEntity = Approval.class, value = "approval"),
@MetaValue(targetEntity = ZoningPermit.class, value = "zoningpermit") })
@JoinColumn(name = "RelatedRecNum", nullable = false)
public BlueserveEntity getNoteOwner()
{
return this.noteOwner;
}
An orm.xml file (auto-generated by seam-gen) exists in this project, though it has no entity mappings and there are no other hbm.xml files. When I remove this file, I no longer receive the exception (that's not a long-term solution).

[Hibernate-JIRA] Created: (HHH-3238) impossible to get the rowcount for a criteria that has projections

impossible to get the rowcount for a criteria that has projections
------------------------------------------------------------------
Key: HHH-3238
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3238
Project: Hibernate3
Issue Type: Bug
Affects Versions: 3.2.6
Environment: hibernate 3.2.6, oracle 10g
Reporter: hbMailingList
Projections.rowCount correctly returns the NUMBER_OF_ROWS for the criteria's resultset.
However if the criteria already has a projection then rowcount no longer returns the NUMBER_OF_ROWS in the result set.
For example:
Criteria c=session.CreateCriteria(Cat.class);
ProjectionList pl = ...;
....
pl.add(Projections.groupProperty("color"));
pl.add(Projections.rowCount());
c.setProjections(pl);
c.list();
will result in the following query:
select color, count(*) from cats group by color
I would expect it to result in:
select count(*) from (select color from cats group by color)
after all if I wanted the count by color I could have simply done:
Projections.count(...)
I really need this feature for my project...if you don't think this will make the release, would you please give me a hint and I'll submit a patch.
Thanks for all the hard work.

[Hibernate-JIRA] Created: (ANN-784) MapBinder.createFormulatedValue() does not honor DB schema name when creating query

MapBinder.createFormulatedValue() does not honor DB schema name when creating query
-----------------------------------------------------------------------------------
Key: ANN-784
URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-784
Project: Hibernate Annotations
Issue Type: Bug
Components: binder
Affects Versions: 3.4.0.GA
Environment: Hibernate 3.3.0.SP1, PostgresQL 8.3
Reporter: Sven Panko
I detected a problem with a ManyToMany mapping using a Map in the following setup:
@Entity
@Table(name = "entitya", schema = "myschema")
class EntityA {
...
@ManyToMany(cascade = { CascadeType.PERSIST, CascadeType.MERGE })
@MapKey(name = "identifier")
@JoinTable(name = "entitya_entityb", schema="myschema", joinColumns = @JoinColumn(name = "entitya_pk"), inverseJoinColumns = @JoinColumn(name = "entityb_pk"))
@Cascade( { org.hibernate.annotations.CascadeType.SAVE_UPDATE, org.hibernate.annotations.CascadeType.DELETE_ORPHAN })
@Cache(usage = CacheConcurrencyStrategy.READ_WRITE)
private Map<String, EntityB> entityBMap = new HashMap<String, EntityB>();
}
@Entity
@Table(name = "entityb", schema = "myschema")
class EntityB {
...
}
The SQL generated to load the entityBMap collection contains a subquery in the select clause, which looks like this:
select a8.identifier from entityb a8 where a8.pk=entityb0_.entityb_pk (entityb0_.entityb_pk comes from the outer select clause)
The problem here is, that entityb in the from clause is not prepended by the schema name "myschema" (the outer query is correctly doing this in the join clause, however). I tracked this down to the createFormulatedValue() method in the MapBinder class; the responsible code snippet is contained in lines 292 - 296:
StringBuilder fromAndWhereSb = new StringBuilder( " from " )
.append( associatedClass.getTable().getName() )
//.append(" as ") //Oracle doesn't support it in subqueries
.append( " " )
.append( alias ).append( " where " );
associatedClass.getTable().getName() does not return the fully qualified table name, so I think this should look something like this:
StringBuilder fromAndWhereSb = new StringBuilder( " from " );
if (associatedClass.getTable().getSchema() != null) {
fromAndWhereSb.append(associatedClass.getTable().getSchema()).append('.');
}
fromAndWhereSb.append( associatedClass.getTable().getName() )
//.append(" as ") //Oracle doesn't support it in subqueries
.append( " " )
.append( alias ).append( " where " );

getIdentifierMethod of BasicLazyInitializer does not match if method invoked through an interface with different return type
----------------------------------------------------------------------------------------------------------------------------
Key: HHH-3502
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3502
Project: Hibernate Core
Issue Type: Bug
Affects Versions: 3.3.1
Reporter: Sean Bridges
Priority: Minor
I have an entity interface,
public interface IEntity {
public Object getId();
}
and I have an entity, say User that implements this interface with an id method
@Id
public Long getId() {
return id;
}
I can call getId() on an uninitialized proxy with,
user.getId()
however, if I call getId() in this way,
((IEntity) user)).getId()
I get org.hibernate.LazyInitializationException: could not initialize proxy - no Session
Looking at the code, BasicLazyInitializer has these lines,
else if ( isUninitialized() && method.equals(getIdentifierMethod) ) {
return getIdentifier();
}
the method.equals(getIdentifierMethod) returns false. The methods are not equal() because they have different return types (this is allowed in 1.5 with covariant return types).
Hibernate should not use Method.equals(), but should instead use the code below (modified from Method.equals(Object)),
public boolean equalsIgnoringReturnType(Method m1, Method m2) {
if ((m1.getDeclaringClass() != m2.getDeclaringClass()) {
return false;
}
if (m1.getName() != m2.getName()) {
return false;
}
Class[] params1 = m1.getParameterTypes();
Class[] params2 = m2.getParameterTypes();
if (params1.length != params2.length) {
return false;
}
for (int i = 0; i < params1.length; i++) {
if (params1[i] != params2[i])
return false;
}
return true;
}
