I have attached the two datasets I'm working with. I need to merge the staffmaster and staffchanges datasets but exclude the people found in the staff changes from the staffmaster dataset. How could I go about doing that? I've attached the two datasets.
Assuming EmpId is Unique :
data want;
merge staff.staffmaster(in=a) staff.staffchanges(in=b);
by empid;
if a and not b;
run;
Assuming EmpId is Unique :

Simply:
proc sql;
create table StaffCurrent as
select * from StaffMaster
where empId not in (select empId from StaffChanges);
quit;
data want;
if 0 then set staff.staffchanges;
if _N_ = 1 then do;
declare hash h(staff.staffchanges);
h.defineKey('empid');
h.defineData(all:"Y");
h.defineDone();
end;
set staff.staffmaster;
rc=h.check();
if rc ne 0;
run;
