Given a sequence like this

select sum(apr) from crsRpt where fisyear = fy into array a1
replace aprTotal with nvl(a1,0)
select sum(may) from crsRpt where fisyear = fy into array a1
replace mayTotal with nvl(a1,0)
select sum(jun) from crsRpt where fisyear = fy into array a1
replace junTotal with nvl(a1,0)

you would think that if the select came up empty the array a1 would become null. However I find that instead of being reset to null the array simply carries over with its prior value. Is there a way to insure that it will be null if the select is empty?

Thanks
