Dear Experts,
I need to fetch the IDs from my dataset based on group by condition.
I'll share my sample data for your reference.
data have;
input ID Des1 Des2 Des3 Des4;
cards;
123 1 0 0 0
123 1 0 0 0
123 1 0 0 0
159 1 0 0 0
159 1 1 0 0
159 0 1 0 0
321 1 0 0 0
456 0 0 0 1
456 1 0 0 0
456 1 0 0 0
;
I expected output as IDs who are Deceased (Des1 =1) first and the rest of Des_ = 0. (Output - 123, 321)
Kindly let me know for any clarification.
Hi @Sathish_jammy ,
Like this:
data have;
input ID Des1 Des2 Des3 Des4;
cards;
123 1 0 0 0
123 1 0 0 0
123 1 0 0 0
159 1 0 0 0
159 1 1 0 0
159 0 1 0 0
321 1 0 0 0
456 0 0 0 1
456 1 0 0 0
456 1 0 0 0
;
run;
data want;
set have;
by id;
if first.id then elig = 1; retain elig;
cond = Des1=1 and sum(Des2, Des3, Des4) = 0 ;
elig = elig * cond;
if last.id and elig then output;
run;
?
All the best

Like this?
proc means noprint;
var Des1 Des2 Des3 Des4;
class id;
ways 1;
output out=have_stat (drop=_:) n= sum= /autoname;
run;
data have_flag;
set have_stat;
flag_des1 = 0;
if Des1_N = Des1_Sum then flag_des1=1; /* Identifies id 123 and 321 for example*/
/*you can compute the flag for Des2, ... also */
run;
proc sql;
create table want as
select a.*, b.flag_des1
from have as a inner join have_flag as b
on a.id=b.id
order by b.flag_des1 desc, a.id;
quit;
