Hello team,

Can someone tell me how to do joins (Left Outer Join, Inner Join) in SAS without using SQL?

Regards,

Hi:
  You will learn about SAS and the MERGE statement in the Programming 2 course. Are you in Programming 1 or Programming 2? The question you asked previously was in relation to the Programming 1 class. Are you working in Programming 1 in the Lesson on SQL? If so, what example are you asking about?

  If you're just curious, here are some resources you might find enlightening:

Hello Cynthia,
I needed it and somehow due to some curiosity.
I don't know if I can learn programming 2 for free. The e-learning used to
have 11 sessions.

Hi:
We revised Programming 1 and Programming 2 several years ago. The old version of Programming 1 with 11 chapters is no longer in sync with the certification exam. You should focus on the new version of Programming 1 and Programming 2. The old version of Programming 2 was also revised. Even if you can't take Programming 2 for free, you can get the Practice Exam for free and you can use the newest Prep Guide to prepare for the certification exam or study Programming 1 and Programming 2 concepts in a condensed form.
Also many countries have discounts for students. In the US, we have discounts for students and veterans and active military; in addition some companies have training discounts.
And, if none of that works out, you can look for papers on the topics covered in Programming 2 such as: functions, formats, do loops, merge, retain, SUM statement, BY Group processing, output control, such as described here: https://support.sas.com/edu/schedules.html?ctry=us&crs=PROG2#s1=3 .

Hope this helps,
Cynthia

Inner

data innerJoin;
merge table1 (in=A) table2 (in=B);
by ID:

if A & B;

run;

Outer Left Join

data outerLeft;
merge table1 (in=A) table2 (in=B);
by ID;

if A;
run;

Hello Reeza,

Thanks for the response!
What determines the left join or inner join?

if A & B?

I appreciate your response.

Yes. If you're studying for the certification exams, I highly recommend reading through this section of the documentation. It's a great overview on the various ways to 'combine' files.

Hello Reeza,

I already have a certificate. I have not used SAS in the job market. I am refreshing my knowledge.
