Hi,
We are suddenly receiving the following exception in our production app when executing a named query which simply loads a collection of Org objects:
Code:

We have the vrsnNbr column defined as not null in the database and there are no records that have a null vrsnNbr.

Here is the mapping file:
Code:
<?xml version="1.0" encoding="UTF-8"?>   
 
<!DOCTYPE hibernate-mapping PUBLIC   
    "-//Hibernate/Hibernate Mapping DTD 3.0//EN"   
    "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">   
 
<hibernate-mapping   
>   
    <class 
        name="com.mycompany.model.hibernate.Org" table="ORG" 
    >   
        <id   
            name="orgId" 
            column="ORG_ID" 
            type="java.lang.Integer" 
        >   
            <generator class="com.mycompany.idgen.SeqPreAllocGen">   
                <param name="sequence">ORG_SEQ</param>   
                <param name="max_lo">50</param>   
            </generator>   
        </id>   
 
        <version   
            name="vrsnNbr" 
            column="VRSN_NBR" 
            type="int" 
        /> 


After googling for many hours I cannot seem to make sense of this exception. Any ideas would be welcomed!

Thanks-

I found out the cause to this issue. It is not the same issue most people are experiencing, according to google. Maybe it will help somebody.

Our named query was returning NULL for a not-null column in a result set. We had to look at the sql hibernate was generating to determine this.

When we ran the sql manually in Sql Developer and sure enough we saw the NULL. This is an Oracle bug and our DBAs have opened a trouble ticket with Oracle.

Thanks-
