Need to sum this column
(t.kolicina)*(sum(s.kolicina)) as 'Kol potr repromat'
When try
sum((t.kolicina)*(sum(s.kolicina))) as 'Kol potr repromat'
Have this error
Msg 130, Level 15, State 1, Line 2
Cannot perform an aggregate function on an expression containing an aggregate or a subquery.
My code
select t.naziv as 'Naziv' ,
(t.kolicina)*(sum(s.kolicina)) as 'Kol potr repromat'
from dbo.normativi_roba t
full join
normativi_lista k
ON t.id_fakture =k.id
full join
mp_racun_roba s
ON k.naziv=s.roba
where roba=(select naziv from dbo.roba_usluge where podgrupa_artikala='HRANA' and roba_usluge.naziv=s.roba)
group by t.naziv, t.jedinica_mjere, t.kolicina
