Yes, I think I understood myself this as well.

We need to write conditional code, unfortunately.

If no span, use my code as is

If there is a span, use

select dDOB from Patients where dDOB is not null and dDOB <> {} and (dDOB ;
between date(year(dDOB),lnMonth1,lnDay1) and (date(year(dDOB),12,31)  OR dDOB between(date(year(DOB),1,1) and date(year(DOB),lnMonth2, lnDay2));
ORDER BY dDOB INTO CURSOR curTest nofilter
