I wrote the following code :
proc sql;
create table new as
SELECT *
FROM A,B
where A.AID= B.BID ;
My output is almost as desired except the ones with missing values.
There are few observations in A where AID is missing and in final output
instead of getting the set of observations as it is, I am getting it repeated
n number of times. Could anybody please tell me the reason for the same.
Instead of entering zeros by hand, you could do
proc sql;
create table base_3 as
SELECT *
FROM A
LEFT JOIN B
ON coalesce(A.AID,0)= B.BID ;
quit;
(untested)

It's your join type that causes the issue, just doing a left join should help, though they'd be blank, not 0
