Merging Two data sets

[Kiko]

Hello, 

I have two datasets called A and  B- group B is a subset of group A (everyone in group B should be in group A), and group B is the people who had an event/outcome, and ultimately I'd like to have a master dataset w. people who had an event and who had not had an event. Then I would like to have a new variable (e.g. outcome) and assign values so that everyone from B should have 1 and the rest of the people have 0. What SAS procedures should I use? Any suggestion/examples would be greatly appreciated. 

Thank you.

This is pretty straighforward if you provide some sample data 🙂

This is data management, combing datasets, which is handled either in a data step or proc SQL. 

Data want;

set A B indsname=source;

source_dsn = source;

run;

Relevant reference, there's many examples here:

If B is a subset of A, you could use this approach:

proc sort data=a;

by id;

run;

proc sort data=b;

by id;

run;

data want;

merge a b (in=b);

by id;

outcome=b;

run;

You haven't told us the names of your variables, so I'm using ID here as the common variable to match on.
