常见数据库分页SQL语句

SQL Server
从数据库表中的第M条记录开始取N条记录，利用Top关键字：注意如果Select语句中既有top，又有order by，则是从排序好的结果集中选择：
SELECT *
FROM ( SELECT Top N *
FROM (SELECT Top (M + N - 1) * FROM 表名称 Order by 主键 desc) t1 ) t2
Order by 主键 asc

例如从表Sys_option（主键为sys_id)中从10条记录还是检索20条记录，语句如下：
SELECT *
FROM ( SELECT TOP 20 *
FROM (SELECT TOP 29 * FROM Sys_option order by sys_id desc) t1) t2
Order by sys_id asc




select * from (select top 20 * from (select top 29 * from m_info_jg)t1)t2 order by id asc



Oralce数据库
从数据库表中第M条记录开始检索N条记录
SELECT *
FROM (SELECT ROWNUM r,t1.* From 表名称 t1 where rownum < M + N) t2
where t2.r >= M
例如从表Sys_option（主键为sys_id)中从10条记录还是检索20条记录，语句如下：
SELECT *
FROM (SELECT ROWNUM R,t1.* From Sys_option where rownum < 30 ) t2
Where t2.R >= 10



minus差分页 select * from table where rownum<=10 minus select * from table where rownum<=5

rownum伪列select * from (select rownum tid,t.* from table t where rownum<=10) where tid<=10 and tid>=5

notin相反select * from table where id not in(select id from table where rownum<=5) and rownum<=5

前题是id排序的select * from table where id>(select max(id) from table where rownum<=5) and rownum<=5

My sql数据库
My sql数据库最简单，是利用mysql的LIMIT函数,LIMIT [offset,] rows从数据库表中M条记录开始检索N条记录的语句为：
SELECT * FROM 表名称 LIMIT M,N

例如从表Sys_option（主键为sys_id)中从10条记录还是检索20条记录，语句如下：
select * from sys_option limit 10,20
