But we may have a request to count each field separately, for which you'd then have to run one select per. Can be done in a single select
	select sum(iif(empty(a), 1, 0))  as CntA;
		, sum(iif(empty(b), 1, 0))  as CntB;
		, sum(iif(empty(c), 1, 0))  as CntC;
		from Rakija ;
		into cursor RakijaTmp

               select Rakija
	
	&& report cursor = Rakija, use RakijaTmp.CntA, .cntB etc as field in summary
