希望各位大虾帮下忙,写个sql语句
部门ID   员工ID   点数 
 000001   000001   3000 
 000001   000002   2000 
 000002   000001   1000 
 000002   000003   4000   
 运行完后结果应该是这个样子 
 员工ID   点数 
 000001   3000   --> 此员工取部门ID为最小的部门ID 
 000002   2000 
 000003   4000 
 ======   有多少个员工ID就显示多少个员工ID   
 谢谢各位大虾了。小弟谢过了。

 from 
  table a 
 where

     select 
       distinct b.员工ID 
     from 
       table b 
     where 
       b.部门ID = ( 
          select 
             min(c.部门ID) 
          from 
             table  c 
          where 
             c.员工ID = b.员工ID 
       ) 
       and b.员工ID = a.员工ID)
------解决方案--------------------create table mtest3 (deptId number(10),workUserId number(10),poit number(10));   
 select workuserid,poit 
 	   from( 
 	   select workuserid,poit 
 	   		  ,row_number()over(partition by workuserid order by deptId ) as rn 
 	   from mtest3 
 	   )

------解决方案--------------------select 员工ID,点数 from 
 table t, 
 ( 
 select 员工ID id,min(部门ID) dep_id from table 
 group by 员工ID 
 ) v 
 where t.部门ID=v.dep_id and t.员工ID=v.id
