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;
}

TableMetadata produce too many output to INFO log level. It good thing if it output be at DEBUG level to not hide other impotant information as service start/stop and other.

[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

Project: Hibernate Tools

Priority: Minor
Hi,
When I reverse engineer against Oracle, unique=true attribute is added to @Column annotation of primary key column. But, when I generate schema from these generated files, Oracle throws "ORA-02261: such unique or primary key already exists in the table" error.
I first ran into this situation while trying Seam and posted the problem to Seam's forum: http://www.jboss.com/index.html?module=bb&op=viewtopic&t=116478. After I got the response, decided to try it without Seam. Then, downloaded the latest HibernateTools & Eclipse Europa and reverse engineered the schema. I saw that generated classes have unique=true attribute which clearly showed that the problem was related with HibernateTools, not with Seam.
Here is the DDL of the table against which I made my test:
CREATE TABLE PEOPLE ("ID" NUMBER NOT NULL, "SURNAME" VARCHAR2(50 BYTE), "NAME" VARCHAR2(25 BYTE), CONSTRAINT "PEOPLE_PK" PRIMARY KEY ("ID"));
Regards,
Ali Sadik Kumlali

I have trouble adding an index to a column of a table which is part of a many-to-many property mapping. The following example causes a NullPointerException when generating the DDL (the exception can be seen at the end of my post):

[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.
