Hi, am wondering if i could please get some help here...
I have a table with duplicate rows for ID. I wanted to loop through column ID, if there are multiple records for the same ID then sum the value.
ID Value
1 5
1 10
2 50
3 5
3 10
3 10
So the resulting table should look like below. I am not sure how to go about it. Can anyone help please?
ID Value
1 15
2 50
3 25
Many thanks in advance!
Michelle
Please try
data have;
input ID Value;
cards;
1 5
1 10
2 50
3 5
3 10
3 10
;
proc sql;
create table want as select id, sum(value) as value from have group by id;
quit;

create table want as select id, sum(value) as value from have group by id;
quit;
by data step
data want;
set have(rename=(value=_value));
retain value;
by id;
if first.id then value=_value;
else value+_value;
if last.id;
drop _value;
run;
Hello Jag, thanks very much! I’ve used your solution and it absolutely worked on my dataset. I thought I had learn about loops but this turns out to be much better.
Thanks again.
Michelle
A Proc Report would also be fine;
proc report data=have nowd out=want (drop=_break_ );
column ID_ value;
define ID_ / group;
run;
