是不是asp把sql自行预处理了一下？？但是偏偏没处理对。。。。

[2416] 15:17:02.530|SQL=[
select a.*,isnull(b.fprevid,-1) fprevid,isnull(c.fnextid,-2) fnextid
from (SELECT * FROM tbInfo where fID='1' ) a
left join (select top 1 1 as fid,fid as fprevid from tbinfo where fid<1 order by fprevid desc) b
on a.fid=b.fid
left join (select top 1 1 as fid,fid as fnextid from tbinfo where fid>1 order by fnextid) c
on a.fid=c.fid
]
好像只要b、c两个子表有一个为空，asp就得不到结果了
而按理说，只要a不空就行了。。。。
