Combina diferentes SQL en una tabla usando SAS

Question

Me gustaría saber cómo combinar diferentes consultas SQL en una sola tabla.

El formato debe ser

customer_no|TOTAL_DIFF_LASTPAYMENT_OPENED_dt|utilization trend| count_enquiry_recency_365|ratio_currbalance_creditlimit 

Tengo dos archivos con datos (ver muestra de datos). Quiero crear una nueva tabla que contenga el resultado de estos PROC.

Ejemplo de datos: 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; 

Answer 1

¿Estás intentando unir el resultado en 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;
