求助 判断语句总是ture

[mbyan]

ur=session("yonghu")
exec="select bl,ed from yonghu where users = '"&ur&"'"
set rs=server.createobject("adodb.recordset")
rs.open exec,conn,3,3
set zj=conn.Execute("select sum(je) as num from xinxi where users='"&ur&"'") 
set bgje=conn.execute("select sum(je) as num from xinxi where users='"&ur&"' and yt like '办公%'")
response.Write(not (bgje.bof and bgje.eof))
response.Write(bgje("num"))
if not(bgje.bof and bgje.eof) then
rs("bl")=0
rs("ed")=zj("num")/2
else
rs("bl")=bgje("num")/zj("num")*100
rs("ed")=zj("num")/2-bgje("num")
end if
rs.update
rs.close

not(bgje.bof and bgje.eof)始终都是ture，这是什么情况啊

select sum(je) as num 这个是聚合运算，肯定返回记录集的， If bgje(0) >0 Then
