我的组页脚中有以下公式,但如果sample_perc为空,则显示0时出现问题;如果#rt_sample_ordered为空,则此值为空。
NumberVar sample_perc := {#rt_sample_ordered}%{@sum_of_sample};
if (sample_perc>0)then
sample_perc
else
0
当sample_perc为空时,如何打印0?
答案 0 :(得分:0)
If Isnull({#rt_sample_ordered}) Or Isnull({@sum_of_sample}) Then
0
Else If ( {#rt_sample_ordered}%{@sum_of_sample} ) > 0 Then
sample_perc
Else
0
