sybase iq分组排序取前N名
营业部客户资产前5客户语句
Sql代码 www.2cto.com

from
(
select

from #ADO_TEMP
)t1 where exists
(
select count(1) from #ADO_TEMP t2 where t1.营业部=t2.营业部 and t1.总资产>t2.总资产
having count(1)<5
) order by t1.营业部,t1.总资产 desc

oracle可以用rank()函数，sybaseiq也有rank()，但是我那机器版本不支持
rank() over(partition by t2.org_full_name order by t1.总资产 desc) pm
