Hello!
I have two data sets I want to merge. One is application information, the second is registrations. There are some who registered but did not fill out an application.
Suppose we have:
Application:
ID Name ... (other variables)
1 Bob
2 Bill
3 Judy
4 John
Registration:
ID Name ... (other variables)
1 Bob
2 Bill
3 Judy
4 John
5 Jake
6 Jack
I know how to merge them as such:
data merge;
merge application (in=a) registration (in = b);
by ID;
if a and b;
run;
However. I would like SAS to also give me an output dataset of those who were not in both application and registration (i.e., ID's # 5 and 6 - Jake and Jack).
So I'd like code to give me two datasets:
Merge:
ID Name... (other variables from both datasets)
1 Bob
2 Bill
3 Judy
4 John
5 Jake
6 Jack
and remainder:
ID Name ...(other variables)
5 Jake
6 Jack
So it gives me the names of just those two where not in the application dataset as well
How can I do this? I've seen it before, but can't remember how to search it unfortunately.
Thanks!
Best,
Gina

Yes, thank you!!
Please also use the search bar, and look at the previous posts. This merging question was asked at least 3 or 4 time yesterday and the day before, and the day before that. Also, post test data in the form of a datastep! You can use the alias to output whre you want e.g.: (and I have not test data to check this on):
data inboth other; merge first (in=a) second (in=b); by keyvariable; if a and b then output inboth; else output other; run;
Thank you!! Yes, it was late at night and I tried but wasn't sure what keywords exactly to use 😞 Good advice re formatting w/ a data step. Will note.
