分页SQl

一、DB2:

     ①.按行号并且按照指定字段降序，取前10条数据SQL

SELECT * FROM (Select 字段1,字段2,字段3,rownumber() over(ORDER BY 指定降序字段 DESC) AS rn from 表名) AS a WHERE a.rn BETWEEN 0 AND 10

      ②.不需降序取前10条数据SQL

SELECT * FROM (Select 字段1,字段2,字段3,rownumber() over() AS rn from 表名) AS a WHERE a.rn BETWEEN 0 AND 10

注：若查询数据含有重复数据则需用方式①，含有重复数据的字段名则为指定字段

二、Mysql:

select * from table limit 0,10

三、Oracle：

从第0行开始取十条记录数据

select * from (select rownum,name from table where rownum <=10) where rownum > 0

四、SQL SERVER

SELECT TOP 页大小 *

FROM Table

WHERE (ID >

(SELECT MAX(id)

FROM (SELECT TOP 页大小*页数 id

FROM 表

ORDER BY id) AS T))

ORDER BY ID
