嵌套for ...循环在SAS

Question

我在SAS中是一个新手，并且在sql中有最新的代码，我已经被暂停了一段时间来在SAS平台上进行转换。我也尝试在SAS中做do..while循环，但它不起作用。

for c in (select * from risk.mv_closed_deals d) loop  
    for DatesToInsert in (select distinct(T1.ACTUAL_DATE) as ACTUAL_DATE from VINTAGE_MTD T1 where T1.Actual_Date>c.closed_date) loop 
    insert into VINTAGE_MTD (dealdate, actual_date, deal_month, mob, dealno, balance, loanamount, overduedays, status, server) 
    values (c.issue_date, DatesToInsert.Actual_Date, to_char(c.issue_date,'yyyy/mm'), 
    (to_char(DatesToInsert.actual_date,'yyyy')-to_char(c.issue_date,'yyyy'))*12 + to_char(DatesToInsert.actual_date,'mm') - to_char(c.issue_date,'mm') - 1, 
    c.dealno, 0, c.loanamount, 0, 0, 'B2'); 
    end loop; 
end loop; 

Answer 1

我会尝试这样的事：

proc sql; 

create table vintage_mdt_new as 
select c.issue_date as dealdate 
     ,DatesToInsert.Actual_Date as actual_date 
     ,put(c.issue_date, yymms.) as deal_month 
     ,intck('month', DatesToInsert.actual_date, c.issue_date) as mob 
     ,c.dealno as dealno 
     ,0 as balance 
     ,c.loanamount as loanamount 
     ,0 as overduedays 
     ,0 as status 
     ,'B2' as server 
from (select * from risk.mv_closed_deals) as c 
    ,(select distinct(T1.ACTUAL_DATE) as ACTUAL_DATE 
     from VINTAGE_MTD T1) as DatesToInsert 
where DatesToInsert.Actual_Date > c.closed_date; 

quit; 

proc append base=VINTAGE_MTD data=vintage_mdt_new; 

还没有尝试过，所以我不知道是否会工作。
