这是什么原因？

上面不是两个同时输出的结果

subjectname=request("subjectname")
sql="select * from exam_subject where subjectname='"&subjectname&"'"
set rs=server.createobject("adodb.recordset")
rs.open sql,conn,3,2
response.write(sql)  如果这样输出结果为select * from exam_subject where subjectname='aa'

subjectname=request("subjectname")
sql="select * from exam_subject where subjectname='"&subjectname&"'"
set rs=server.createobject("adodb.recordset")
rs.open sql,conn,3,2
if rs.eof and rs.bof then
  response.write(sql)   如果是这样：输出结果为select * from exam_subject where subjectname=''
  response.end()
end if

不知道什么原因,请大家帮帮忙！！
