一：Oracle
select * from (select rownum,name from table where rownum <=endIndex )
where rownum > startIndex
或
select * from table where rownum > startIndex and rownum <=endIndex (默认升序排列)
取查询结果中的startIndex 至 endIndex 的记录
二：DB2
DB2分页查询
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
以上表示提取第10到20的纪录
select * from (select rownumber() over(order by id asc ) as rowid from table where rowid <=endIndex )
where rowid > startIndex
三：MySQL
select * from table limit start, pageNum
pageNum：记录数
