Hi all,
When merging datasets, is there a proc sql equivalent to the 'if a and not b' statement in data steps?
Thank you,
Marco
Yep, there are a few ways. One could be:
proc sql;
create table want as
select A.ID
from WORK.A A
left join WORK.B B
on A.ID=B.ID
where B.ID is null;
quit;

You can also do it in SAS if it makes it easier for you.
Proc sort data= a;
by Id;
run;
Proc sort data= b;
by ID;
run;
data abc;
merge a(in=a) b;
by ID;
if a=1;
run;
