> * the criteria
> Criteria criteria = getActorDao().createCriteria();
> criteria.add(Restrictions.or(
>       Restrictions.ilike("name", "adi"),
>       Restrictions.ilike("description", "adi")
>       ));
> criteria.setProjection(Projections.projectionList()
>       .add(Projections.groupProperty("name"), "name")   
>       .add(Projections.groupProperty("description"), "description")   
>       );
> criteria.setResultTransformer(new AliasToBeanResultTransformer(ActorTestDTO.class));
> List result = criteria.list();
> * the generated SQL (show_sql=true):
> select this_.name as y0_, this_.description as y1_
> from Actor this_
> left outer join Action this_1_ on this_.id=this_1_.id
> left outer join Location this_2_ on this_.id=this_2_.id
> left outer join UserGroup this_3_ on this_.id=this_3_.id
> left outer join WebUser this_4_ on this_.id=this_4_.id
> where (lower(y0_) like ? or lower(y1_) like ?)
> group by this_.name, this_.description
> * the Problem
> This generated SQL works on HSQLDB but NOT on MS-SqlServer.
> The wrong code:
> where (lower(y0_) like ? or lower(y1_) like ?)
>  
> The correct code:
> where (lower(this_.name) like ? or lower(this_.description) like ?)
>  
> I verified this by issuing the sql directly in SQL-server.
