SQL Query : Select LinkContent, LinkID, LinkParent, Level from tblsitemaplinks where LinkID in (select distinct LinkID from tblrolelinks where RoleID=?) and Status=1 order by Displayorder

SQL Query with Inner Join:

select tbstmplnks.linkContent, tbstmplnks.id, tbstmplnks.linkParent,tbstmplnks.displayOrder, tbstmplnks.level from Tblsitemaplinks as tbstmplnks join tbstmplnks.tblrolelinks as tblrllnks where tblrllnks.roleID=1 and tblrllnks.status=1 order by tblrllnks.displayorder




Using Hibernate API:
List lst1 = (List) session.createCriteria(Tblsitemaplinks.class,"tblstmlnks").
add(Expression.eq("status",1)).createCriteria("tblrolelinks","tbrlnks").add(Restrictions.eq("tbrlnks.roleID",1)).list();



Genrated Query:
select this_.LinkID as LinkID33_1_, this_.LinkName as LinkName33_1_, this_.LinkContent as LinkCont3_33_1_, this_.LinkParent as LinkParent33_1_, this_.Level as Level33_1_, this_.DisplayOrder as DisplayO6_33_1_, this_.Status as Status33_1_, this_.AddedBy as AddedBy33_1_, this_.DateAdded as DateAdded33_1_, this_.UpdatedBy as UpdatedBy33_1_, this_.DateUpdated as DateUpd11_33_1_, tbrlnks1_.RoleLinkID as RoleLinkID6_0_, tbrlnks1_.Status as Status6_0_, tbrlnks1_.Displayorder as Displayo3_6_0_, tbrlnks1_.AddedBy as AddedBy6_0_, tbrlnks1_.DateAdded as DateAdded6_0_, tbrlnks1_.UpdatedBy as UpdatedBy6_0_, tbrlnks1_.DateUpdated as DateUpda7_6_0_, tbrlnks1_.LinkID as LinkID6_0_, tbrlnks1_.RoleID as RoleID6_0_ from tblsitemaplinks this_ inner join tblrolelinks tbrlnks1_ on this_.LinkID=tbrlnks1_.LinkID where this_.Status=? and tbrlnks1_.RoleID=?


My Question: I can achieve the same using the direct HQL, but I want to achieve using the hibernate API..I am getting error when I add this line add(Restrictions.eq("tbrlnks.roleID",1)) with the partial constructed call as shown above in Using Hibernate API. The attribute roleID is foreign key of table Tblroles. I am using hibernate-3.2.3 with mysql 5.2.
Error:
