--------------------------------------------------------------------------------------------------------------------
Key: HHH-2548
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2548
Project: Hibernate3
Issue Type: Bug
Affects Versions: 3.2.3
Environment: tomcat 5.5, eclipse3.2, jre1.5, postgreSQL8.1, hibernate3 and
hibernate3.2
Reporter: Yu Deng
Priority: Critical
<hibernate-mapping package="com.grapevinecs.ams.domain.perbranch.inv">
<class name="InvItem">
<id name="id" column="id">
<generator class="hilo"/>
</id>
...
<many-to-one name="transferredDetails"/> <!-- FK: Points to
corresponding entry for transferred inventory items -->
....
</class>
(another mapping file)
</hibernate-mapping>>
<hibernate-mapping
package="com.grapevinecs.ams.domain.perbranch.inv">
<class name="InvTransferDetails" >
<id name="id" column="id">
<generator class="hilo"/>
</id>
<property name="returnedToICBC"
type="com.grapevinecs.ams.dao.BooleanInteger" not-null="true"/>
...
</class>
</hibernate-mapping>
Probelm:
1) The result returns 3000 records ---- select count(*) from InvItem c where
upper(c.invType) LIKE '%D%' and c.invSeries.closed = '0' and c.branch
=60551 order by c.transferredDetails.returnedToICBC asc, c.stamp asc,c.invNmbr asc
2) result List return size 0 by this query --- from InvItem c where upper(c.invType)
LIKE '%D%' and c.invSeries.closed = '0' and c.branch =60551 order by
c.transferredDetails.returnedToICBC asc, c.stamp asc,c.invNmbr asc
1) is correct but 2) is not correct. only when transferredDetails in InvItem not null be
returned. in case 2), I have no transferredDetails not null.
after I excuted the query 2), even I remove "c.transferredDetails.returnedToICBC
asc", the result is still return nothing.
