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.zzzyk.com  

select  

*  

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
