Need a way to query only for specific class types or turning off check for subclasses ------------------------------------------------------------------------------------- Key: HHH-2443 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2443 Project: Hibernate3 Type: Task Versions: 3.1.3 Environment: 3.1.3, oracle 10.2.0.2 Reporter: Jason I have two generic tables with the possibility of a lot of data in each. One called instance and one called association. Each has there own properties table instance_property and association_property. They each have there own mapping files which I will list below. In the code, Association extends Instance. So the problem I am having is everytime I query for Instance i.e. HQL - from instance i where type=:type. This will create two queries "select i.* from instance i where i.type=:type" and "select i.* from association i where i.type=:type". Since Instance, Association, InstanceProperty, and AssociationProperty have there own mapping files and they both have there own tables (therefore no discriminators), how can I only have it query on Instance? And querying on Association is fine since it does not have subclasses and it only executes one query. Am I missing something, or is this just not possible at this time? In summary, I am requesting a way for HQL to only query on the instance class I specify without checking the subclasses. <!-- Instance --> <class name="Instance" table="instance"> <cache usage="read-write" /> <id name="id" column="id" type="java.lang.Long"> <generator class="assigned" /> </id> <version name="version" column="version" type="long" /> <map name="propertiez" table="instance_to_property"> <cache usage="read-write" /> <key column="instance_id" /> <index column="name" type="string" /> <many-to-many class="InstanceProperty" column="instance_property_id" fetch="join" /> </map> </class> <class name="InstanceProperty" table="instance_property"> <cache usage="read-write" /> <id name="id" column="id" type="long"> <generator class="native" /> </id> <version name="version" column="version" type="long" /> <property name="name" column="name" type="string" not-null="true" /> <property name="key" column="is_key" type="boolean" not-null="true" /> <property name="value" column name="value" type="string"/> </property> </class> <!-- Association --> <class name="Association" table="association"> <cache usage="read-write" /> <id name="id" column="id" type="java.lang.Long"> <generator class="assigned" /> </id> <version name="version" column="version" type="long" /> <map name="propertiez" table="association_to_property"> <cache usage="read-write" /> <key column="association_id" /> <index column="name" type="string" /> <many-to-many class="AssociationProperty" column="association_property_id" fetch="join" /> </map> <property name="referenceId1" column="referenceId1" type="java.lang.Long" /> <property name="referenceId2" column="referenceId2" type="java.lang.Long" /> </class> <class name="AssociationProperty" table="association_property"> <cache usage="read-write" /> <id name="id" column="id" type="long"> <generator class="native" /> </id> <version name="version" column="version" type="long" /> <property name="name" column="name" type="string" not-null="true" /> <property name="key" column="is_key" type="boolean" not-null="true" /> <property name="value" column name="value" type="string"/> </property> </class> -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
