一、条件字段为数值的情况
select * from tb where id=@id; --当前记录
select top 1 * from tb where id>@id order by id; --下一条记录
select top 1 * from tb where id<@id order by id desc --上一条记录
二、以排序的思路出发的一种方案
;WITH TUsers AS ( SELECT *, ROW_NUMBER() OVER (ORDER BY vcUserID) AS _ROW
FROM DB_Fast_Users.dbo.T_Users AS A(NOLOCK)
)SELECT *
into #T
FROM TUsers
-- 上一条select B.*
from #T AS A(NOLOCK)
left join #T AS B(NOLOCK) ON B._ROW = (A._ROW - 1)
where A.vcUserID=‘Test1‘
-- 下一条select B.*
from #T AS A(NOLOCK)
left join #T AS B(NOLOCK) ON B._ROW = (A._ROW + 1)
where A.vcUserID=‘Test1‘
drop table #T
