N-M条记录 1. select top m * into 临时表(或表变量) from tablename order by columnname -- 将top m笔插入 set rowcount n select * from 表变量 order by columnname desc 2. select top n * from (select top m * from tablename order by columnname) a order by columnname desc 3. 如果tablename里没有其他identity列,那么: select identity(int) id0,* into #temp from tablename取n到m条的语句为: select * from #temp where id0 >=n and id0 <= m如果你在执行select identity(int) id0,* into #temp from tablename这条语句的时候报错,那是因为你的DB中间的select into/bulkcopy属性没有打开要先执行: exec sp_dboption 你的DB名字,'select into/bulkcopy',true 4. 如果表里有identity属性,那么简单: select * from tablename where identitycol between n and m
--MSSQL select * from (select top 1 * from tb where id>5 order by id asc)a union all select * from (select top 1 * from tb where id<5 order by id desc)b
1.
select top m * into 临时表(或表变量) from tablename order by columnname -- 将top m笔插入
set rowcount n
select * from 表变量 order by columnname desc
2.
select top n * from
(select top m * from tablename order by columnname) a
order by columnname desc
3.
如果tablename里没有其他identity列,那么:
select identity(int) id0,* into #temp from tablename取n到m条的语句为:
select * from #temp where id0 >=n and id0 <= m如果你在执行select identity(int) id0,* into #temp from tablename这条语句的时候报错,那是因为你的DB中间的select into/bulkcopy属性没有打开要先执行:
exec sp_dboption 你的DB名字,'select into/bulkcopy',true
4.
如果表里有identity属性,那么简单:
select * from tablename where identitycol between n and m
select * from
(select top 1 * from tb where id>5 order by id asc)a
union all
select * from
(select top 1 * from tb where id<5 order by id desc)b
小F mssql这样的语句是什么?
建议你列出你的表结构,并提供测试数据以及基于这些测试数据的所对应正确结果。
参考一下这个贴子的提问方式http://topic.csdn.net/u/20091130/20/8343ee6a-417c-4c2d-9415-fa46604a00cf.html
1. 你的 create table xxx .. 语句
2. 你的 insert into xxx ... 语句
3. 结果是什么样,(并给以简单的算法描述)
4. 你用的数据库名称和版本(经常有人在MS SQL server版问 MySQL)
这样想帮你的人可以直接搭建和你相同的环境,并在给出方案前进行测试,避免文字描述理解上的误差。
