sqlserver的3种分页方式
sqlserver的3种分页方式
sqlserver的3种分页方式,如下:01 ---sqlServer 2005 分页语句集合
02 ----缺点:
03 -- top:必须用户编写复杂sql,不支持复合主键
04 -- max:必须用户编写复杂sql,不支持非唯一列排序
05 --row:不支持sqlserver2000
06 --------------------------------
07 select TOP @pagesize id,email,qq,wechart,phone,phone1 FROM contact
08 where id not in
09 (SELECT TOP (@pagesize*(currentpage-1)) id from contact ORDER BY id ASC )
10 ORDER BY id ASC
11
12
13 -- 效率最低下的分页语句(只需要知道页数和每页的显示数目即可)
14 select * from AISINO_BD_TelephoneRecord order by ID asc;
15 select top 5 ID ,companyID,projectID from dbo.AISINO_BD_TelephoneRecord
16 where ID not in(
17 select top (5*(2-1)) ID from AISINO_BD_TelephoneRecord order by ID asc
18 ) order by ID asc
19
20
21 ----------------------
第二种方法,只需要知道页数和每页的显示数目即可-------------------------------
22
23 select top 5 * from AISINO_BD_TelephoneRecord
24 where ID>(
25 select max(ID)
26 from (select top (5*(2-1)) ID from AISINO_BD_TelephoneRecord order by ID asc)tt
27 )
28 order by ID asc

-第三种方法---只需要知道页数和每页的显示数目即可----------------------------------

33
34 select *
35 from (select top (5*(1-1)+5) row_number()over(order by Id asc)__rn__, * from AISINO_BD_TelephoneRecord)t
36 where __rn__>5*(1-1)
在oracle 中的分页:
oracle 自带了rownum ,直接使用rownum 进行分页:
1
select *
2
from (select a.*, rownum nm
3
from (select * from aos_rms_user) a
4
where rownum <= 5*(1-1)+5)
5
where nm >= 5*(1-1)
