主要目的是为了实现分页查询。
7 个解决方案
#1
select top n-m * from 表
where 字段 not in (select top m 字段 from 表)
where 字段 not in (select top m 字段 from 表)
#2
--第一种方法
--第11条到第20条,共选出10条记录
select *
from (select top 10 * from (select top 20 * from 表名 order by ID) t1 order by ID desc) t2
order by ID
--第二种方法
--第11条到第20条,共选出10条记录
select top 10 *
from 表名
where ID>(select max(ID) from (select top 10 ID from 表名 order by ID) t1)
order by ID
--或者加辅助列处理
--第11条到第20条,共选出10条记录
select *
from (select top 10 * from (select top 20 * from 表名 order by ID) t1 order by ID desc) t2
order by ID
--第二种方法
--第11条到第20条,共选出10条记录
select top 10 *
from 表名
where ID>(select max(ID) from (select top 10 ID from 表名 order by ID) t1)
order by ID
--或者加辅助列处理
#3
--增加辅助列,给表增加自动ID,如:
alter table 表名 add id int identity(1,1)
select *
from 表名
where id between 100 and 200
alter table 表名 add id int identity(1,1)
select *
from 表名
where id between 100 and 200
#4
使用临时表加辅助列处理吧
#5
select top n-m * from 表
where 字段 not in (select top m 字段 from 表)
where 字段 not in (select top m 字段 from 表)
#6
用TOP的效率是比较高的
从test表中取出第 n 条到第 m 条的记录:
SELECT TOP m-n+1 *
FROM test
WHERE (id NOT IN
(SELECT TOP n-1 id
FROM test))
id 为test表的关键字
从test表中取出第 n 条到第 m 条的记录:
SELECT TOP m-n+1 *
FROM test
WHERE (id NOT IN
(SELECT TOP n-1 id
FROM test))
id 为test表的关键字
#7
取n到m条记录的语句
1.
select top m * from tablename where id not in (select top n * from tablename)
2.
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
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:
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 identitycol between n and m
1.
select top m * from tablename where id not in (select top n * from tablename)
2.
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
3.
select top n * from
(select top m * from tablename order by columnname) a
order by columnname desc
