Hello,

I would like rewrite following SQL query to HQL:

update mf_rezerwacja MR set rezerwacja = rezerwacja -
(
SELECT sum( MO.kwota ) FROM mf_operacja_na_zadaniu MO
where MR.rok = MO.rok
)

and in all cases my HQL give error :

right-hand operand of a binary operator was null

HQL:

update MfRezerwacja MR set MR.rezerwacja = MR.rezerwacja -
(
select sum( MO.kwota ) FROM MfOperacjaNaZadaniu MO
where MR.rok = MO.rok
)

Is possible do this in HQL ?

regards
