[Hibernate-JIRA] Created: (HHH-2223) BatchFetchQueue.getXXXBatch() cache check impeding batch fetching
by Joel Caplin (JIRA)
BatchFetchQueue.getXXXBatch() cache check impeding batch fetching
-----------------------------------------------------------------
Key: HHH-2223
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2223
Project: Hibernate3
Type: Bug
Components: core
Versions: 3.2.0.ga
Environment: 3.2.0GA, Mac OS X/Solaris 10, Sybase 12.5/HSQLDB
Reporter: Joel Caplin
Priority: Minor
Attachments: testcase.tar
I have attached a test case which demonstrates the issue at hand by implementing a cheap data model: Pub >---|- Manager -|--< Employee
Pub and Employee are uncached; Manager is cached (tried under both Eh and the non-prod HashMap implementation). All associations are lazy. The test case has a default batch size of 10 and uses hsqldb to demonstrate the problem - which was diagnosed against Sybase.
When BatchFetchQueue.getXXXBatch() is invoked, it does not load any objects it finds in the second level cache - it merely acknowledges their presence by logging to INFO (isCached()). This in turn means that any child associations in that cached object will not have a proxy created for them.
Suppose we want to find all the employees of the pubs in our database. We choose to do this by loading all the Pubs ("FROM Pub") and calling thePub.getManager().getEmployees() iteratively.
When the managers are in the second level cache, Hibernate issues 11 select statements: one to load the pubs and one for each distinct manager.
When the Managers are not in the cache, Hibernate issues 3 select statements: one to load the pubs, one to load the managers and one to load the employees.
A solution might be to load the object from the cache instead of just ignoring it?

[Hibernate-JIRA] Created: (HHH-3032) On Sybase, a subquery is incorrectly generated, causing ''Incorrect syntax near the keyword 'as'.
by Fernando Galdino (JIRA)
On Sybase, a subquery is incorrectly generated, causing ''Incorrect syntax near the keyword 'as'.
-------------------------------------------------------------------------------------------------
Key: HHH-3032
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3032
Project: Hibernate3
Issue Type: Bug
Affects Versions: 3.2.5
Environment: Hibernate 3.2.5, JDK 1.6, IDE Eclipse 3.3, running on Windows XP
Reporter: Fernando Galdino
I am using Spring 2.5 and Hibernate. I created a method to find a list of ProductPositionData based on an existence of its details represented by class DetalhePosicaoProdutoData. So, there is a relationship 1:n between tables ProductPosition and DetalhePosicaoProduto.
public List<ProductPositionData> findAllBy(Date date, String viewCode, String status)
{
DetachedCriteria subquery = DetachedCriteria.forClass(DetalhePosicaoProdutoData.class);
subquery.add(Expression.eq("indSituaRegis", status));
subquery.add(Expression.eq("compositeId.datPosic", date));
subquery.setProjection(Projections.distinct(Property.forName("tipDolar")));
DetachedCriteria criteria = DetachedCriteria.forClass(ProductPositionData.class);
criteria.add(Expression.eq("indSituaRegis", status));
criteria.add(Subqueries.exists(subquery));
List<ProductPositionData> list = this.hibernateTemplate.findByCriteria(criteria);
return list;
}
It should generate a query on the format SELECT blablabla FROM xyz WHERE exists (SELECT 1 FROM wyz). In really, running this method, I got a similar query.
select [ommitted field names]
from dtb_trd_resultado.resu.tbl_posicao_produto_trd this_
where this_.ind_situa_regis=? and exists (select distinct this0__.tip_dolar as y0_
from dtb_trd_resultado.resu.tbl_det_posicao_produto_trd this0__ where this0__.ind_situa_regis=? and this0__.dat_posic=?)
It causes the following error running under Sybase:
Incorrect syntax near the keyword 'as'.
; nested exception is com.sybase.jdbc2.jdbc.SybSQLException: Incorrect syntax near the keyword 'as'.
It happens because on the subquery is generated this0__.tip_dolar as y0_ but "as y0_" is not valid in Sybase because using alias is not allowed for Sybase subqueries.
I saw similar problems at:

[Hibernate-JIRA] Created: (HHH-2280) Not-Null Constraint-Violation with unidirectional one-to-many mapping
by Robert Herschke (JIRA)
Not-Null Constraint-Violation with unidirectional one-to-many mapping
---------------------------------------------------------------------
Key: HHH-2280
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2280
Project: Hibernate3
Type: Bug
Versions: 3.2.0.cr4
Environment: Hibernate 3.2.0.cr4, Oracle 10XE
Reporter: Robert Herschke
Priority: Blocker
Attachments: one-to-many-test.zip
In some cases it is neccessary to have an unidirectional one-to-many mapping, but not using Join-Tables due to a legacy database system.
So it must be possible, to have a one-to-many mapping just via a foreign-key-mapping. The Child-Object must not know the Parent-Object in this case.
It must also be possible, to pay respect to a NOT-NULL-Constraint at this foreign-key due to restrictions on legacy database systems.
Hibernate doesn't support this, but throw a NOT-NULL-Constraint Violation Exception. The documentation says, "this is unusual" - to which I want to dissent.
See the attached testcase for details, that is adopted from your "one-to-many" testcase found in the 3.2.0 sources.

Spell check functionality needed
--------------------------------
Key: HSEARCH-269
URL: http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-269
Project: Hibernate Search
Issue Type: New Feature
Components: engine, mapping
Affects Versions: 3.2.0
Reporter: John Griffin
Assignee: John Griffin
>From Emmanuel:
- more than one field and even more than one index should be the source of the dictionary
- declaring which field is part of a dictionary should be declarative @AddToDictionary(name="main-dictionary")
(with probably an optional field name(s))
- for a given dictionary name, we need to associate an index and probably a field prefix (to share the same index
for all dictionaries). This couold be by annotations or in the configuration (not sure)
- this index should be kept like any other DirectoryProvider in the HSearch intrastructure (we could then reuse
ReaderProvider internally and don't have leaks).
- we will probably add a manual dictionary reindex method and the SpellChecker API should be in the SearchFactory.
sf.getDictionary("main-dictionary").spellcheck(word, suggestion);
sf.getDictionary("main-dictionary").spellcheck(word, suggestion, entity, properties...); //not sure how useful is this one really
sf.getDictionary("main-dictionary").reindex();
this needs to be refined.

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: (ANN-677) Blob is null with Postgresql
by Aaron Luchko (JIRA)
Blob is null with Postgresql
----------------------------
Key: ANN-677
URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-677
Project: Hibernate Annotations
Issue Type: Bug
Affects Versions: 3.2.1
Environment: hibernate-3.2.1, hibernate-annotations-3.2.1, postgresql-8.2.5-1.fc7, postgresql-jdbc-8.2.504-1jpp.fc7 and postgresql-8.2-506.jdbc4.jar
Reporter: Aaron Luchko
Attachments: hibPostgresbug.zip
I've found that after a sequence of queries, starting new transactions and clearing the session, a Blob will not be successfully from the database and null will be returned by the InputStream instead. Using the debugger I've followed this into the jdbc code and from what I can tell some message is sent to load the blob but the database replies with an empty set of data which naturally causes the InputStream to read null.
I've attached a test case (sorry, no makefile or pom.xml, I just ran it using eclipse) which, for me, replicates the bug.
Note I've also used hsqldb and mysql and didn't see the bug with them, only postgresql.
thanks,
Aaron
