这句语名的<>0表示什么意思 ,谢谢!
if request("typeid")<>0 then
sql="select * from spzs where cpmc like '%"&request("txtitle")&"%' and sortid="+cstr(sortid)+" and typeid="+cstr(typeid)+" order by ID desc"
else
sql="select * from spzs where cpmc like '%"&request("txtitle")&"%' and sortid="+cstr(sortid)+" order by ID desc"
end if

不等于0
