IsNull、rs、sum

<%
'response.write (IsNull(rs("month_finish_count_price")))
If IsNull(rs("month_finish_count_price"))=true Or Rs("month_finish_count_price") = "" then
response.write "--"
else
response.write (rs("month_finish_count_price"))
end if
%>

If IsNull(rs("month_finish_count_price"))=true   可以去掉  '=true '

直接写成：If IsNull(rs("month_finish_count_price"))
