Hi,

I already posted this in the german forum but got no answers. Maybe the chance for replys is higher here. There is an issue (see http://opensource.atlassian.com/project ... se/ANN-654 ) that could fit my problem but also there is no solution but the question for a test case. I have a test case but it does not match exactly. I'm quite new to hibernate and possibly I'm just doing something wrong. Any help is appreciated. I collected all data available but if you need anything more just ask.

What it does:
Started with the option -s it sets up the database just like hibenate has done it on my pc and fills in some data.
Started with the option -t1 it fetches the data with a working map.
Started with the option -t2 it fetches the data and fails.

The only thing that's different between the working and the failing map is the option used for LazyCollectionOption. TRUE is working, EXTRA is failing. In the last case there is an extra column created in the SQL named null. I'm pretty sure it should be named KEY to select exactly the line searched for.
Can someone tell me what's going wrong?

Hibernate version:
Code:
Hibernate Annotations 3.3.0.GA
Hibernate 3.2.5


Mapping documents:
Code:
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration
    PUBLIC "-//Hibernate/Hibernate Configuration DTD//EN"
    "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<hibernate-configuration>

        <property name="dialect">org.hibernate.dialect.HSQLDialect</property>
        <property name="hibernate.show_sql">true</property>
    </session-factory>
</hibernate-configuration>

The rest is done i the code. See below.

Code between sessionFactory.openSession() and session.close():
Code:
Criteria criteria = session.createCriteria(FailingMap.class);
FailingMap map = (FailingMap) criteria.uniqueResult();
int value = map.getMappedValue("Test");
System.out.println("Value for Test: "+value);

Name and version of the database you are using:
Code:
HSQLDB 1.8.3


The generated SQL (show_sql=true):
Code:
select mapelement0_.KEY as KEY1_0_, mapelement0_.VALUE as VALUE1_0_ from ELEMENT mapelement0_ where mapelement0_.MAP_ID=? and mapelement0_.null=?

That's the problem! There is a null column where there should be a colum named KEY.
