语句如下：
Set rs=conn.execute( "select * from studentinfo where idcard= ' "&idcard& " ' ")
if rs.eof and rs.bof then
errormsg= "3 "
response.Redirect "client_stuinfofind.asp?errormsg= "&errormsg
Set rs=nothing
end if
total=rs.recordcount
执行后查询到两条记录，想看看总共多少条记录，使用rs.recordcount，但是rs.recordcount的为-1
------解决方案--------------------
conn.execute 是没有游标的,要用adOpenKeyset游标
set rs = server.createobject( "adodb.recordset ")
rs.open "select *** ", conn, adOpenKeyset, adLockReadOnly
------解决方案--------------------
rs.open "select *** ", conn1,3
