我搞定了  
  like   this:  

      select   *   from   (select   rownum   as   m,a.*   from   scc_user   a)     where   m   between   3   and   8  

      Top

楼上的说的对,可这仍是单表查询啊。我自己搞定了。谢谢各位:)      

      select   *   from    

                                        (select   rownum   rid,user_id,user_name,user_dept,user_position,user_salary      

                                        from  
                            (select   info.user_name,salary.*    

                                      from   zdy_userinfo   info,   zdy_salary   salary    

                                                where   info.user_id=salary.user_id    

                                          order   by   info.user_id   )  

                                                )   where   rid   between   1   and   5;  

                  在二层查询中不可用表名,无效,只需用列原名即可。  
          二层查询中不该有info_id,否则外部的user_id成为未明确定义的列。

我程序中测试的。取前30条,主要oracle没有类似sql server的top
select * from  
(
  Select a.*, ROWNUM RN  From
  (SELECT c.customer_code,c.customer_character,c.customer_officer,c.customer_balance,c.customer_creditline,l.*
   from loan_fact_loans l left join loan_fact_customer c on l.customer_id = c.customer_id
   Order By loans_balance Desc,loans_date Desc ) a
)Where RN <= 30
