在ORACLE中,写法是 select * from (select rownum rn,t.* from 表名 t where rownum>=n) temp where temp.rn<=m
但是在SQLSERVER中好像没有rownum的语法,应该怎样实现该功能呢?我只知道选择前n行的写法 select top n * from 表名
但是在SQLSERVER中好像没有rownum的语法,应该怎样实现该功能呢?我只知道选择前n行的写法 select top n * from 表名
(select row_number() over(order by getdate()) no,* from tb) t
where no between n and m
FROM
(select ROW_NUMBER()over(SELECT 1) rn,* from 表名 )T
WHERE rn BETWEEN n AND m
SELECT *
FROM
(select ROW_NUMBER()over(ORDER BY (SELECT 1)) rn,* from 表名 )T
WHERE rn BETWEEN n AND m
select top (n-m+1) * from tablename where id not in (select top n id from tablename order by id asc/*|desc*/) 2.
select top m * into 临时表(或表变量) from tablename order by columnname -- 将top m笔插入到临时表
set rowcount n --只取n条结果
select * from 表变量 order by columnname desc 3.
select top n * from
(select top m * from tablename order by columnname) a
order by columnname desc
4.如果tablename里没有其他identity列,那么:
先生成一个序列,存储在一临时表中.
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
5.如果表里有identity属性,那么简单:
select * from tablename where identity_col between n and m 6.SQL2005开始.可以使用row_number() over()生成行号
;with cte as
(
select id0=row_number() over(order by id),* from tablename
)
select * from cte where id0 between n to m

指定一個值,不改到表的顯示順序
select 1 from dual;oracle等同
