I can do same in joins
proc sql;
create table l3 as select a.id,a.id2 from table1 as a right join table2 as b
on a.id=b.id2;
quit;
proc print;run;
OK. Easy.
Assuming your id2 in table2 has no replicated value.
data table1; input id id2; cards; 1 2 2 3 3 4 4 5 ; run; data table2; input id id2; cards; 2 3 ; run; data want; if _n_ eq 1 then do; if 0 then set table2; declare hash ha(dataset:'table2', hashexp:10); ha.definekey('id2'); ha.definedone(); end; set table1; if ha.check(key:id)=0 then output; run;
