造周数据存储过程

造周数据存储过程
 
由于工作需要要求把天的数据转成周的,花了一点时间写了一个。
 
记录如下:  www.zzzyk.com  
[sql] 
create or replace procedure g_yearweek is  
i number :=1;  
CURSOR c_chn IS  
select distinct(n_chn_id) from auditplatform.sum_mchn_mtgt_day_n_fina;  
  
begin  
   
for chn_rec in c_chn  
  loop  
  dbms_output.put_line(chn_rec.n_chn_id);  
 for i in 158..321  
  loop  
        
  insert into sum_mchn_schn_yearweek (  
n_week_id,n_chn_id,  
n_pv,n_pv_user,n_sch)    
select i,chn_rec.n_chn_id,trunc(avg(d_n_pv)),trunc(avg(d_n_pv_user)),trunc(avg(d_n_sch))  
  from auditplatform.sum_mchn_mtgt_day_n_fina t, auditplatform.dim_sys_yearweek w  
 where to_date(vc_stat_date, 'yyyymmdd') <= w.dt_date_end  
   and to_date(vc_stat_date, 'yyyymmdd') >= w.dt_date_beg  
   and w.n_week_id = i and t.n_chn_id = chn_rec.n_chn_id;  
  
end loop;  
  
end loop;  
commit;  
  
end g_yearweek;

[sql] 
SQL> set serveroutput on;  
SQL> exec g_yearweek;
