[hibernate-issues] [Hibernate-JIRA] Created: (HHH-2158) incorrect hql query on one-to-one with property-ref

incorrect hql query on one-to-one with property-ref ---------------------------------------------------- Key: HHH-2158 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2158 Project: Hibernate3 Type: Bug Components: core Versions: 3.2.0.ga Environment: hibernate 3.2.0.ga with firebird 1.5.3 and jaybird 1.5.5 driver on windows XP Reporter: Sebastien Cesbron Attachments: testhib.zip I have a one-to-one relationship with property-ref between Master and Slave2. I want to find all Master instances that have a null Slave2 instance associated. To do so my query is select master from Master master where master.slave2 is null The sql generated is select master0_.oid as oid0_, master0_.libelle as libelle0_ from Master master0_ where master0_.oid is null which seems incorrect. It checks here Master instances with null id (config files are listed below). If I do my query like this select master from Master master where master.slave2.oid is null the generated sql is ok : select master0_.oid as oid0_, master0_.libelle as libelle0_ from Master master0_, Slave2 slave2x1_ where master0_.oid=slave2x1_.myMaster and (slave2x1_.oid is null) I have attached a small eclipse project that reproduces the problem This problem may-be related to the one I have submitted as issue HHH-1849 -- 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
