I need to nest an aggregate query in another HQL query, so I write this :
Code:
IQuery queryCommesseODL = this.m_session.CreateQuery("select odl from OrdineDiLavoro as odl inner join odl.Commessa as com where odl.Stato <> 'C' and odl.Commessa.Stato <> 'C' and odl.MatricolaSviluppatore=:dev and ((odl.OreTotali+(odl.MinutiTotali/60)) > (select (sum(gnt.Ore)+(sum(gnt.Minuti)/60)) from Gantt as gnt where gnt.Matricola=odl.MatricolaSviluppatore and gnt.Cliente.Codice=odl.CodiceCliente and gnt.Anno=odl.Anno and gnt.Numero=odl.Numero))");
but I got exception, so I tried to simplify my query but I always got exception: finally I tried a super simple query and I'm getting strange work:
these queries works
Code:
select gnt.Ore , gnt.Minuti from Gantt as gnt
select sum(gnt.Ore) , sum(gnt.Minuti) from Gantt as gnt
these fails with following exception
Code:
select gnt.Ore + gnt.Minuti from Gantt as gnt
select sum(gnt.Ore) + sum(gnt.Minuti) from Gantt as gnt
select sum(gnt.Ore) , sum(gnt.Minuti)/60 from Gantt as gnt
Exception
Code:
NHibernate.QueryException: , expected in SELECT [select sum(gnt.Ore) , sum(gnt.Minuti)/60 from FinitenessEvo.Domain.Gantt as gnt]

Why ?
