"sum(prod) as produkter,sum(prod_ur) as produkter_ur," & _
"sum(sa) as servabon,sum(fors) as forsabon,sum(ma) as teleabon" & _
" from hitrate_ordreposter ordre " & _
" join hitrate on hitrate.navn = ordre.navn " & _
" where hitrate.dataset = '" & Dataset.ToUpper & "' and extract(month from hitrate.dato)= '" & Month & "'  and extract(year from hitrate.dato) = '" & Year & "'" & _
" group by hitrate.navn,hitrate.dataset,extract(month from hitrate.dato),extract(year from hitrate.dato)"
