Vasyl Zhabko commented on HHH-2158:
-----------------------------------

Is anybody going to fix that? We having this issue whenever we are using one-to-one ralationship and it is optional on one side. There is no way to get it perform well with Criteria API or HQL. Only workaround is to map not required side as a collection (Set, etc)  and in class wrap it up in single property that will assume collection will always consist of one element or nothing.

> 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
