Hi, I'm trying to use proc sql to merge 2 tables.. I want the matches (between the 2 tables) to be sent to Table A and the non matches to table B. I'm sure this is extremely easy for some.
Thanks
Well, its easier in datastep (note id is just adhoc, change to your matching vars):
data both others;
merge have1 (in=a) have2 (in=b); /* assumes sorted */
by id;
if a and b then output both;
else output others;
run;
Alternatively in SQL (no need to sort):
proc sql;
create table BOTH as
select A.*,
B.*
from HAVE1 A
inner join HAVE2 B
on A.ID=B.ID;
create table OTHERS as
select A.*,
B.*
from HAVE1 A
full outer join HAVE2 B
on A.ID=B.ID;
quit;
Well, just typed that out from memory so may not be. Not actually tested it as no SAS at the moment, so take with a pinch of salt. Thanks for pointing out Haikuo.
When you use LEFT JOIN or RIGHT JOIN , make sure using WHERE not ON clause .
