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;
