数据库查询的问题
我现在有个表A 字段id

有5条数据 1，2，3，5，6

然后我现在要查询的是 怎么通过ID查询到 “4”（也就是说ID里面不包含的那个数字）

ID可以当作是累加的，中间可能有个别漏掉的，我现在就是想把漏掉的给找出来

小白 求教

数据量多么？是SQL2005还是？

SQL code

--SQL2005;with ach as(    select rid=row_number() over (order by getdate())    from master..spt_values a,master..spt_values b    where a.type = 'P' and b.type = 'P')select a.ridfrom ach a left join tb b on a.rid = b.idwhere b.id is null
