<% set rs= Server.CreateObject("adodb.recordset")
rs.open "select top 20 simpicture,cntitle,simclass,id from z_product where simclass=class2 and simpicture<>'' order by [top] desc,listnum desc,id desc",conn,1,1
do while not rs.eof %>

------解决方案--------------------
rs.open "select top 20 simpicture,cntitle,simclass,id from z_product where simclass='"&class2&"' and simpicture<>'' order by [top] desc,listnum desc,id desc",conn,1,1


试试
------解决方案--------------------
看看你表中字段类型，simclass,simpicturep这两个字段是什么类型。
数值型的不用加'',字符型的需要加''
------解决方案--------------------
rs.open "select top 20 simpicture,cntitle,simclass,id from z_product where simclass="&class2&" and simpicture<>'' order by [top] desc,listnum desc,id desc",conn,1,1
