i want to remove if the id has not duplicate, like as below. Thisis table example i have now
id desc i
15 W100786 1
15 03/21/1970 2
20 K64478 1
20 02/14/1968 2
21 M157842 1
22 W250143 1
22 02/15/2000 2
i need the table as below:
id desc i
15 W100786 1
15 03/21/1970 2
20 K64478 1
20 02/14/1968 2
22 W250143 1
22 02/15/2000 2
So i need to remove the id:21, because it doesn't have duplicate.
If you're data is already sorted by ID then a small data step would work:
data want; set have; by ID; if not(first.id and last.id); run;

Or, if your data isn't sorted, try SQL GROUP BY, with a HAVING count(*) =2.
Or NOUNIQUEKEY.
data have;
input id desc : $20. i;

run;
proc sort data=have out=want nouniquekey;
by id;
run;
