分享一个union all SQL语句,怎么写分页存储过程?
select id,cpname from cp where cpname like"%22%" union all select id,cnname from cp2 where cpname like"%22%"
这个SQL语句怎么来写一个分页存储过程?数据库SQL2005有没有分页存储过程可以执行这个SQL语句.?求高手帮忙.

上面这些存储过程,我想执行select id,cpname from cp where cpname like"%22%" union all select id,cnname from cp2 where cpname like"%22%" 这个SQL语句,用ASP怎么调用?
必用我用第二个存储过程@Tables 是cp
后面的2个WHERE 语句怎么来放置?

呵呵,谢谢大家帮忙,不过,我那个SQL语句,可以用这些存储过程吗?我那个语句中有union all ,这个放在上面的分页存储过程里面.好像不行把.

select id,cpname from cp where cpname like"%22%" union all select id,cnname from cp2 where cpname like"%22%"
先把你的这个结果放到一张临时表中，然后分页，这样会比较简单一些
