数据库MySQL、Oracle、SQLServer、db2分页查询语句

#pagesize 为每页的大小.

#pagenumber为要显示页面页面号.

#查看学生表的2班学生

mySQL查询分页语句：

select * from studenttb where stuclass='2' limit pagesize*(pagenumber-1),pagesize*pagenumber;

Oracle查询分页语句：

需要分组分页：

select * from （

select t.*,rownum from (select * from studenttb where stuclass='2' order by stugender) t

)where rownum>pagesize*(pagenumber-1) and rownum<=pagesize*pagenumber；

基本分页：

select * from （

select t.*,rownum from studenttb t where stuclass='2'

)where rownum>pagesize*(pagenumber-1) and rownum<=pagesize*pagenumber；

SQLServer查询分页语句：

查询语句1：

select * from (

select row_number() over(order by stuno asc)as row_number,* from studenttb where stuclass='2'

)as tl where tl.row_number between pagesize*(pagenumber-1) and pagesize*pagenumber;

下边SQLServer三种分页方案默认页大小为10，开始位置：页大小*(页数-1)

top方案：

select top 10 * from table1

where id not in(select top 开始的位置 id from table1)

max方案:

select top 10 * from table1

where id>(select max(id)

from (select top 开始位置 id from table1order by id)tt)

row方案:

select *

from (

select row_number()over(order by tempcolumn)temprownumber,*

from (select top 开始位置+10 tempcolumn=0,* from table1)t

)tt

where temprownumber>开始位置

效率: top方案 < max方案 < row方案(max)

db2查询分页语句：

1:

SELECT * FROM (

Select 字段1,字段2,字段3,rownumber() over(ORDER BY 排序用的列名 ASC) AS rn from 表名

) AS a1 WHERE a1.rn BETWEEN 10 AND 20;

2:

select * from (

select rownumber() over(order by id asc

) as rowid from table where rowid <=endIndex

) where rowid > startIndex;
