Combine different SQL into one table using SAS

问题:

I would like to know how to combine different SQL queries into one table.

The format should be

customer_no|TOTAL_DIFF_LASTPAYMENT_OPENED_dt|utilization trend| count_enquiry_recency_365|ratio_currbalance_creditlimit 

I have two files with data (see data sample). I want to create a new table that contains the output of these PROC's.

Data sample: https://www.dropbox.com/sh/k7qz6m8w0yqenn7/AAAgYcVhHxCRNhiX5ZvK0q5Aa?dl=0

/*  TOTAL_DIFF_LASTPAYMENT_OPENED_dt */

proc sql;  
  select customer_no, avg(TOTAL_DIFF_LASTPAYMENT_OPENED_dt)  
  from account_30_sort  
  group by  customer_no  ;  
quit;   

---

/*  utilization trend */  
proc sql;  
  select customer_no, sum (cur_balance_amt /creditlimit) / avg  
 (cur_balance_amt/(creditlimit+creditlimit))  
  from account_30_sort  
  group by  customer_no;  
quit;  

---

/*  count_enquiry_recency_365 */   
DATA  WORK.ENQUIRY_30;  
    SET ENQUIRY_30;  
    num_days= dt_opened -  enquiry_dt;      
RUN;   

proc sql;  
  select customer_no, sum(enq_amt)   
  from ENQUIRY_30  
  where num_days <=365  
   group by  customer_no;    
quit;

---

/*  ratio_currbalance_creditlimit */  
 proc sql;  
  select customer_no, sum( cur_balance_amt/ creditlimit)  
  from account_30  
  group by  customer_no  
  ;  
quit;

Are you trying to join the result on customer_no?

   proc sql;
    create table want as
    select t1.customer_no
          ,avg(t1.TOTAL_DIFF_LASTPAYMENT_OPENED_dt) as proc1
          ,sum(t1.cur_balance_amt /t1.creditlimit) / avg(t1.cur_balance_amt/(t1.creditlimit+t1.creditlimit)) as proc2
          ,sum(t2.enq_amt) as proc3
          ,sum(t3.cur_balance_amt/ t3.creditlimit) as proc4
    from account_30_sort t1
        ,enquiry_30(where=(dt_opened - enquiry_dt <= 365)) t2
        ,account_30 t3
    where t1.customer_no=t2.customer_no
      and t2.customer_no=t3.customer_no
    group by t1.customer_no
    ;
    quit;
