Bidirectionnal many-to-one with formula and one-to-one doesn't work -------------------------------------------------------------------- Key: HHH-2076 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2076 Project: Hibernate3 Type: Bug

Components: core Versions: 3.2.0.cr4 Reporter: Xavier Brénuchon Attachments: onetoone_bidirectionnal_formula.zip Hello, There is a bug with one-to-one association with foreign key associations (doc 5.1.11). I use composite-id and a formula in many-to-one : <class name="Person"> <composite-id> <key-property name="company" type="string" column="COMPANY"/> <key-property name="name" type="string" column="NAME"/> </composite-id> <property name="age" type="int" column="AGE"/> <many-to-one name="car" class="Car" unique="true"> <formula>company</formula> <column name="FK_CAR_REGISTRATION"/> </many-to-one> </class> <class name="Car"> <composite-id> <key-property name="company" type="string" column="COMPANY"/> <key-property name="registration" type="string" column="REGISTRATION"/> </composite-id> <property name="color" type="string" column="COLOR"/> <one-to-one name="person" class="Person" property-ref="car"/> </class> I have a problem because Hibernate can't use a formula in the right part of outer join : DEBUG SQL:393 - select this_.COMPANY as COMPANY1_1_, this_.REGISTRATION as REGISTRA2_1_1_, this_.COLOR as COLOR1_1_, person2_.COMPANY as COMPANY0_0_, person2_.NAME as NAME0_0_, person2_.AGE as AGE0_0_, person2_.FK_CAR_REGISTRATION as FK4_0_0_, person2_.company as formula0_0_ from Car this_ left outer join Person person2_ on this_.COMPANY=person2_.null and this_.REGISTRATION=person2_.FK_CAR_REGISTRATION DEBUG AbstractBatcher:476 - preparing statement DEBUG JDBCExceptionReporter:63 - could not execute query [select this_.COMPANY as COMPANY1_1_, this_.REGISTRATION as REGISTRA2_1_1_, this_.COLOR as COLOR1_1_, person2_.COMPANY as COMPANY0_0_, person2_.NAME as NAME0_0_, person2_.AGE as AGE0_0_, person2_.FK_CAR_REGISTRATION as FK4_0_0_, person2_.company as formula0_0_ from Car this_ left outer join Person person2_ on this_.COMPANY=person2_.null and this_.REGISTRATION=person2_.FK_CAR_REGISTRATION] java.sql.SQLException: Column not found: NULL in statement [select this_.COMPANY as COMPANY1_1_, this_.REGISTRATION as REGISTRA2_1_1_, this_.COLOR as COLOR1_1_, person2_.COMPANY as COMPANY0_0_, person2_.NAME as NAME0_0_, person2_.AGE as AGE0_0_, person2_.FK_CAR_REGISTRATION as FK4_0_0_, person2_.company as formula0_0_ from Car this_ left outer join Person person2_ on this_.COMPANY=person2_.null and this_.REGISTRATION=person2_.FK_CAR_REGISTRATION] at org.hsqldb.jdbc.Util.throwError(Unknown Source) at org.hsqldb.jdbc.jdbcPreparedStatement.<init>(Unknown Source) at org.hsqldb.jdbc.jdbcConnection.prepareStatement(Unknown Source) at org.hibernate.jdbc.AbstractBatcher.getPreparedStatement(AbstractBatcher.java:497) at org.hibernate.jdbc.AbstractBatcher.getPreparedStatement(AbstractBatcher.java:415) at org.hibernate.jdbc.AbstractBatcher.prepareQueryStatement(AbstractBatcher.java:139) at org.hibernate.loader.Loader.prepareQueryStatement(Loader.java:1561) at org.hibernate.loader.Loader.doQuery(Loader.java:661) at org.hibernate.loader.Loader.doQueryAndInitializeNonLazyCollections(Loader.java:224) at org.hibernate.loader.Loader.doList(Loader.java:2144) at org.hibernate.loader.Loader.listIgnoreQueryCache(Loader.java:2028) at org.hibernate.loader.Loader.list(Loader.java:2023) at org.hibernate.loader.criteria.CriteriaLoader.list(CriteriaLoader.java:95) at org.hibernate.impl.SessionImpl.list(SessionImpl.java:1569) at org.hibernate.impl.CriteriaImpl.list(CriteriaImpl.java:283) at org.hibernate.impl.CriteriaImpl.uniqueResult(CriteriaImpl.java:305) at org.hibernate.test.onetoone.bidirectionnalformula.OneToOneBidirectionalFormulaTest.testReadOneToOneBidirectionalFormula(OneToOneBidirectionalFormulaTest.java:47) In fact this problem is linked with HHH-944. Soon, I will send a patch which corrects this bug and makes an evolution for HHH-944.
