在SQL Developer的循环

Question

同样存在悍然再用错误..

不是一个单一群组功能

我有一个空表mig_temp1，我想，以填补观察）） 这个选择有什么问题？

begin 
    for j in 1..7 loop 
    for t in 0..32 loop 
     insert into mig_temp1 (report_date, portfolio, bucket, Q) 
     select add_months(to_date('31.10.2014','DD.MM.YYYY'),-t), 
      cp.portfolio, j, count(*) 
     from proba_cft pr, credtoportfolio cp 
     where pr.credit_num = cp.credit and pr.dpd_47 between 30*(j-1)+1 and 30*j; 
    end loop; 
    end loop; 
end; 

Answer 1

应该通过cp.portfolio与一群工作：

begin 
    for j in 1..7 loop 
    for t in 0..32 loop 
     insert into mig_temp1 (report_date, portfolio, bucket, Q) 
     select add_months(to_date('31.10.2014','DD.MM.YYYY'),-t), 
      cp.portfolio, j, count(*) 
     from proba_cft pr, credtoportfolio cp 
     where pr.credit_num = cp.credit and pr.dpd_47 between 30*(j-1)+1 and 30*j 
     group by cp.portfolio; 
    end loop; 
    end loop; 
end;
