Some query fail in BinaryLogicOperatorNode.mutateRowValueConstructorSyntaxesIfNecessary when there is a one-to-one bidi relation. --------------------------------------------------------------------------------------------------------------------------------- Key: HHH-3199 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3199 Project: Hibernate3 Issue Type: Bug Components: query-hql Affects Versions: 3.2.6 Environment: Hibernate version 3.2.6.ga. Database postgreSQL, Reporter: Benjamin Lerman Attachments: example.zip When mapping a one-to-one bidi relation with the following mappings : <hibernate-mapping> <class lazy="true" name="com.genia.toolbox.model.association.one_to_one_bidi.impl.DriverOneToOneBidiImpl" proxy="com.genia.toolbox.model.association.one_to_one_bidi.DriverOneToOneBidi" table="_driver_one_to_one_bidi"> <id name="identifier" column="_identifier" type="java.lang.Long" unsaved-value="null"> <generator class="hilo"><param name="table">_hibernate_unique_key_169</param></generator> </id> <one-to-one cascade="persist,merge,save-update" class="com.genia.toolbox.model.association.one_to_one_bidi.impl.CarOneToOneBidiImpl" name="carInternal" property-ref="driverInternal"/> </class> </hibernate-mapping> and <hibernate-mapping> <class lazy="true" name="com.genia.toolbox.model.association.one_to_one_bidi.impl.CarOneToOneBidiImpl" proxy="com.genia.toolbox.model.association.one_to_one_bidi.CarOneToOneBidi" table="_car_one_to_one_bidi"> <id name="identifier" column="_identifier" type="java.lang.Long" unsaved-value="null"> <generator class="hilo"><param name="table">_hibernate_unique_key_181</param></generator> </id> <many-to-one cascade="persist,merge,save-update" class="com.genia.toolbox.model.association.one_to_one_bidi.impl.DriverOneToOneBidiImpl" name="driverInternal" column="_driver" unique="true"/> </class> </hibernate-mapping> the following query: FROM com.genia.toolbox.model.association.one_to_one_bidi.DriverOneToOneBidi AS a2, com.genia.toolbox.model.association.one_to_one_bidi.CarOneToOneBidi AS a3 WHERE ((a2.carInternal)=(a3)) failed with an exception: left and right hand sides of a binary logic operator were incompatibile This is due to the call to the method mutateRowValueConstructorSyntaxesIfNecessary of BinaryLogicOperatorNode. One of the type is a OneToOneType which returns 0 for getColumnSpan while the other is a ManyToOneType that returns 1. The two values are not equal and an exception is thrown. I join to this issue the relevant classes and mappings. -- 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
