sql 分页查询

引用:http://space.itpub.net/26273/viewspace-704021

初始定义:

pageSize:每页显示大小

pageNum:第几页

Oracle分页:

minus差分页:

select * from table where rownum<=pageSize*pageNum minus select * from table where rownum<=(pageSize-1)*pageNum

例子:

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

 两个关联表的符合条件记录的交集,是于union作用相反.

:

 select  *  from  table  where  rownum<=20  

 minus    

 select  *from  table  where  rownum<=10

 

SQLServer分页:

select top pageSize*pageNum from table where id not in(select top (pageSize-1)*pageNum id from table );

例子

select top 5 * from table where id not in(select top 0 id from table);

 

MySQL分页:

select * from table limit (pageSize-1)*pageNum,pageSize*pageNum;

例子:

select * from table limit 0,5;
