1、oracle数据库:(注:tableName.id指的是tableName的主键)

select * from

(select tableName.*,rownum as con from tableName

where rownum <= m

order by tableName.id desc)

where con >= n;


2、SQLServer数据库:(注:tableName.id指的是tableName的主键)

实现原理解释:

1)先查出前m面条记录

2)再查出前n面条记录

3)最后通过条件过滤掉前m条记录

方法一:

select top n-m+1 * from tableName

where tableName.id not in

(select top m tableName.id from tableName order by desc tableName.id)

order by tableName.id

方法二:

select top n-m+1 * from tableName as a where not exists

(select * from

(select top m * from tableName order by id desc) b

where b.id = a.id)

order by id desc


3、MySQL数据库:

select * from tableName limit m, n;
